How to Use Small Concrete Batching plant

After you start a small concrete batching plant, you should ensure the rotation speed of mixing drum is normal. Before you adding new materials, you should discharge the finished concrete. The machine can not work overload. During operation, you must make it sure that the sand and stone would not drop into devices and components. If there is something wrong, you should cut off the power firstly.
When you begin using a small concrete mixing plant, you should check all the units and systems in it, and put it in use according to the operation instruction. Then, you should check there is no materials in mixing drum before starting it. Besides, you should make it sure that the drum and mixing blades are in normal situation. You should also check all the devices of small concrete batching plant are normal.

What Are the Models of Concrete Batch Plant

Today,Haomei will introduce the using scope of concrete batching plant’s model and we hope it can help you.
Concrete batching plant has single concrete mixer plant and double concrete mixers plant, by definition, every single concrete mixer plant has one mixing console, double concrete mixers plant with two mixing consoles, each concrete mixer corresponding to a mixing discharging port, so double concrete mixers plant is a stand-alone plant 2 times of production capacity.
The concrete mixing plant is named as the production capacity per hour, at present, the models in our country are:HZS60, HZS75,HZS120, HZS150, HZS180, etc. Haomei commercial concrete batch plant has good mixing performance ad adopts screw twin shaft concrete mixer as the main host which not only has strong mixing performance, but also can mix dry hard concrete, plastic concrete and various proportion concrete.

Four Features Introduction of HZS concrete batching plant

Haomei will introduce four characteristics of HZS concrete batching plant for you:
The application of engineering concrete mixing plant is more popular than the ordinary concrete batching plant. Wide application field. one concrete batching plant can produce different kinds of concrete.
Cheap. As the configuration is quite simple, the price, of course, is very cheap. The price of Engineering concrete mixing plant.
Low configuration and easy to operate. The concrete produced by the concrete batching plant is for their own use. As the number of the cement silos of the HZS concrete batching plant and the additives is small the batching materials in the controlling system is mixed according to the proportion of their own needs, it relatively saves capital and is easy to control.
On the other hand,Small size configuration and convenient to arrange. Compared to the commercial concrete batching plant, the number of cement silos and additives, and the covering area are smaller. In the construction sites, there are more choices to place the engineering concrete batching plant.

Maintain the concrete Batch Plant as Requirements

1.After starting for the first time and removing failures of electric system, check the rotation direction of mixing arms before start your machine. The half dry concrete will stick on the mixing shaft and increase the mixing shaft diameter which will reduce the mixing efficiency and loose power. So, users should keep the mixing shaft clean.
2.Continuous concrete batching plant.We suggest our customer clean the machine after one working period or before the initial setting time of mixture concrete in any production interruption time. Adjust the mixing blade in time in order to ensure the clearance is 3.5mm. The new machine should be checked every day, after using one week, you can check it every week. After starting concrete mixing plant for everyday, make it run in empty for a period of time. Listen whether there is grating between mixing shaft and mixing drum.
When we taking regular maintenance work for mixing device of concrete batch and mixing plant, the working efficiency will be increased continuously and the failure rate will reduce.

Different Concrete Mixer has Different Mixing Effect

now ,we will introduce the mixing effect differences between single shaft concrete mixer and double shaft concrete mixer.
Double shaft concrete mixer rotates in radial direction and axial direction at the same time during the mixing process. Its primary mixing zone is in the circumferential direction of the agitator. The mixer takes full advantage of the mixing space to mix the aggregate, cement and water. As a result, the mixer can achieve the most optimal mixing mode and obtain the best mixing effect.
Single shaft concrete mixer can mix plasticity concrete, rigid concrete, light aggregate, mortar, etc. It has the advantages of wide application range, good mixing quality, high production efficiency and low energy consumption. Therefore, it is an ideal choice for construction sites as well as small and medium sized concrete batching plants.
The mixing principle of single horizontal shaft is basically similar with self-falling concrete mixer . The function of its shafts and blades is to raise the aggregates to a certain height, and then make them fall freely. Therefore, in operating process, the effective working volume of single shaft concrete mixer is larger than theoretical designed volume. The overall height of single horizontal concrete mixer is bigger than double shaft concrete mixer.

Operate Batch Plant According to Right Steps

Except for the quality of the machine will cause failures, the right and normal operation of the equipment also will cause failures. Here, Haomei will introduce five steps to tell you how to operate concrete batching plant correctly.
Check every indictor of concrete batching plant timely, and regularly check whether the clutch, brake and lifter are flexible and reliable or not. The machine can not work until all the parts have reached normal standard.
Check the internal and external circuits of mixing building, and make the insulation of every circuit be kept good. The exposed rotating parts of the machine should be set up with protection device.
The big stone and other iron products must not be put into the storage, and anyone can not stand under the lifting hopper and close to conveyor belt.
The operation and observation place of mixing building should be set up with work platform and safety rails. The operator can not check the mixing building in the process of operation.
Anyone can not enter into the mixing bin, and he can not put the sundries into the bin. The operator should check the mixing bin before operating the machine, and make sure the escalator of mixing bin is safe and reliable.

Small concrete pump truck FAQ

Now, in construction on the pump is an irreplaceable role in the. Here is truck driver in the operation often encounter a variety of problems, here HAOMEI Machinery equipment Co., Ltd. Star-ming will provide you with answers to frequently asked questions:
1, pump arm fast how slow the point?
You can adjust the parity above multi-way valve orifice screw, thereby regulating the flow sheet valve, to regulate the speed of the purpose of the boom. Manufacturers do not recommend you to adjust the relevant buttons.
2. Pump Truck shaking too much how to deal with?
Inside the cabinet to turn off the boom cushioning effect but little more, or adjust the boom position and then put a small displacement or more, as the legs firmly support some, the problem itself steel boom.
3, how to lift GPS lock boom pump?
If you do not pay the car models are recommended on schedule or not lifted, manufacturers know very troublesome. If you have already paid the car models it can only be modified electronic control of the whole, not computer controlled.
4, concrete pump truck pumped back why not?
Concrete pump can not be pumped to the car, although the turntable can take 365-degree rotation of the boom can be turned back, but the center of gravity in the truck behind the car, back after pumping more rearward center of gravity mobile, the risk of rollover-prone, it is not pumped back! This situation can be put down to drive around a little on it.
5, the general construction of concrete pump require much space?
Almost to a diameter of 12 meters of space to be conducive to the smooth terrain it additional pump, next have to have a space for a U-turn mixer. But in general depends on the width of the front legs and rear legs, pumping the length of the pump is not the same. Secondly Also note that there is no space above obstacles such as wires, finally, to ensure the normal and depart into the concrete mixer, preferably have two venues car the car will meet the above requirements on it.

The reason of small concrete pump truck oil temperature too high

We use a small concrete pump to work when sometimes encounter the oil temperature rise quickly, very high, and it was found unable to pump commutation failure to solve this problem we must first analyze its reasons, experienced drivers master should be aware that this situation is mostly caused by the hydraulic system leak. Well, we are going to talk about it on the specific troubleshooting methods:
We can check the hydraulic pressure of the oil outlet for this failure, if pressure is normal on the import and export and then measuring the accumulator pressure, if the pressure is low, then the accumulator air bag has been broken, replace the accumulator If the test machine fault still exists, you can check the oil between the pump and the accumulator, since between the pump and the accumulator is not compromised,Therefore only possible within the one-way valve between the pump and the accumulator vent lead to temperature rise, reversing weakness. Just down within a period of time, be able to hear the pressure oil unloading "hissing" sound, you can open a one-way valve, you will find the sealing surface of the valve is badly worn, and the hydraulic oil cloudy, with a slight emulsification. You can now replace the check valve and hydraulic oil after the test machine, you can find Tuobeng return to normal.
The current small pump products, most with a 1-2 or hydraulic oil table, a whole oil, a branch table. Then with the oil temperature table, when found in the mailbox of the hydraulic oil increases, often need to determine the cause of the failure to use the above exclusion, despite the exclusion of time required is also not a lot. But at the construction site, as early as one minute if you can solve the problem, the construction unit, is to reduce the losses and increase the benefits.

Development of mobile concrete mixer

Concrete mixer firstly appeared in the form of self-falling concrete mixer. With the constantly increasing requirements of concrete, the compulsory concrete mixer came into being. Compulsory concrete mixer can be classified into vertical shaft type and horizontal shaft type. The two kinds of concrete mixers almost occupy the domestic market.
The self-falling concrete mixer can date back to 20th century and the drum concrete mixer driven by steam engines has started to emerge. In the following 50 years, the reverse discharging and tilting discharging of double cone concrete mixer and the drum concrete mixer were born in succession.
self loading concrete mixer
in the early 1950s, compulsory concrete mixer has developed and promoted rapidly. It is composed of turbo-prop concrete mixer and planetary concrete mixer. After 1970s, with the application of light-weight aggregate, the circular groove horizontal shaft compulsory concrete mixer which is also horizontal shaft concrete mixer appeared. It can be divided into two types: single shaft and twin-shaft, which has features of self-falling mixing and compulsory mixing.Compulsory concrete mixer is developed successfully in the early 1980s. But it develops quickly and has far surpassed many other models in the product specification and product quantity. The mixer is the core of compulsory concrete mixer and it is closely connected with mixing quality, production efficiency and using and maintenance costs. It is composed of double circular groove drum which is placed horizontally, two mixing shafts which rotate in the opposite direction and mixing blades.

How to Distinguish the Quality of Concrete batching Plant

Though concrete mixing plant is commonly used in the infrastructure construction, most customers only know about the application of Concrete batching Plant and know little about how to distinguish the quality of concrete mixing plant, let alone to check the quality of Concrete batching Plant they buy. Today, Haomei machinery gives customers some advices about ways of distinguishing the quality of concrete mixing plant.
The operation of transmission system should be flexible and there must be no strange sound in it.The installation of matched circuit should be reasonable and the equipment installation should be correct. If the concrete mixer is self falling mixing drum, the jumpiness range of discharging mouth should not exceed 1% of the diameter of the charging mouth. Check the steel quality of the screen mesh of vibrating screen on the concrete mixer, the reasonable size of screen mesh and sieve pore, and the installation accuracy of screen mesh.The belt conveyor, hopper lifter, cantilever dragline and so on should transmit smoothly, operate flexibly, brake reliably and have no abnormal noise and chain blocking.The quality of cement silo should be qualified.The safety valve should have no air leakage phenomenon.The inlet and outlet of measuring hopper should smooth and there should be no accumulated material and spilth phenomenon.The examination of measuring system also attaches great importance and users should check the sensitivity and accuracy of measuring system.Pay attention to the increasing temperature of reducer and it should conform to the temperature on the instruction book.

How to the Classify Commonly Used Concrete Mixer

According to mixing principle, commonly used concrete mixer can be classified into self-falling concrete mixer and compulsory concrete mixer.
Structure of self falling concrete mixer: the mixing drum of self falling concrete mixer is placed according to the principle of vertical mixing. With the rotation of mixing drum, the concrete mixture is turned and mixed in the mixing drum through free falling, which can realize the aim of mixing. Self falling concrete mixer is mainly used to mix plastic concrete and low fluidity concrete. The barrel and mixing blades wear less and are easy to clean, but they consume more power and have low efficiency. Generally, the mixing time of self falling concrete mixer is 90-120s/dish. Because the self falling concrete mixer has great abrasion to concrete aggregate and can affect the quality of concrete, it is gradually replaced by compulsory concrete mixer day by day.
Structure of compulsory concrete mixer: there are several groups of mixing blades in the mixing drum and mixing blades rotate around vertical shaft and horizontal shaft to mix materials compulsorily until the materials are mixed evenly. This kind of concrete mixer has strong mixing effect, which is suitable for mixing dry hard concrete and light aggregate concrete, and also it can be used to mix low fluidity concrete. Compulsory concrete mixer has advantages of good mixing quality, quick mixing speed, safe and simple operation, etc. However, the machine parts wear quickly and compulsory concrete mixer is often used the high strength alloy steel or other wear resistance materials as lining, which is mainly applied to concrete batching plant or precast factories.

Operating Procedure of Haomei Twin Shaft Concrete Mixer

Before starting the twin shaft concrete mixer, check whether there is bruised phenomenon between the rotating pars and the mixing drum firstly. If so, adjust it in time.
Clean the sundries in the mixing drum.After the mixing drum is limited, operators can start the concrete mixer.The rotating direction of mixing shaft should be consistent with the mark of cylinder face.Eliminate the metal and other sundries in the stored materials.
Adjust the timing of concrete mixer according to mixing time and the adjustment should be done when cutting down power supply.Press the rising button and the mixing spade will rotate which is driven by main shaft.Shut down the concrete mixer automatically when it arrives the setting time.
When discharging materials, shut down the concrete mixer firstly. Open the pin, move the handle to make the charging barrel rotate to a certain place, lock the pin to locate the rotating main shaft and discharge the mixture out of the charging barrel.
After discharging mixture, reset the barrel manually and locate the pin of the mixing drum.When cleaning the mixing drum, pour water into mixing drum and clean it by the rotation of main shaft. Or clean the mixing drum with dry sand.

How to Reduce the Power Consumption of Concrete Mixer

First,we neeed Reduce the frictional resistance of every component. Carry out the mechanical technique maintenance regulations strictly and lubricate it according to rules, which can reduce the resistance loss of operating mechanism, such as the frictional resistance between drum tyres and the surface of running pulley, the frictional resistance between the supporting axle of running pulley and shaft sleeve and the resistance of hoisting hopper. In this way, the mechanical efficiency improves.
second,Reduce the mechanical invalid load. The reduction of mechanical invalid load can be realized by taking measures from the processes of charging materials, mixing and discharging materials: put down the charging hopper timely after discharging, which can reduce the energy consumption of vibration. Master the mixing time correctly and discharge materials at the right moment under the condition of ensuring the concrete quality, which can reduce the power consumption. Discharge materials thoroughly. If sticky materials in the mixing drum are too many, eliminate them. The excessive remaining materials not only affect the productivity, but also increase the power consumption.
in the end,Shorten the time of mechanical test run. Except for starting the machine according to operating procedures and the test run time of routine maintenance, in the process of construction, shorten the time of mechanical test run as mush as possible. As for the electric concrete mixer, if the test run time exceeds 1 minute which is caused by untimely feeding, and the concrete transporting and pouring, shut down the machine without load.

The Electric System of Concrete batching Plant

When the concrete baching plant is operating, it is necessary to ensure that the electric system can catchup with the working process, so concrete baching plant has high requirement of the performance of electric system. What are these requirements of electric system in detail?
First,The electric system should realize easy input, convenient operation and the accurate adjustment and modification of the setting point of every kind of material. Electric system must possess perfect self-locking and interlock function, which can the reliable and accurate operation of the electric system. As for the commonly seen faults, electric system should be provided with faults detection and alarming function.
Sometimes, concrete mixing plant should be operated in night, so there must be a headlamp. Because the headlamp is a necessary part of electric system, the electric system should ensure that the headlamp should be controlled flexibly.When the weighing system of concrete mixing plant sets the zero output, the electric system can remove the tare and amend the gap. As for the single measurement of the single king of material, electric system should have a function of deduction and supplement, which can effectively control the measuring precision. Besides, the electric system should have lighting alarming device.

The Cement Quality of Concrete batching Plant

The cement quality directly affects the quality of architecture and the durability. And what’s more, it is the key link of the quality control of concrete batching plant. Clinker. As for the standard requirements, calcium metasilicate mineral accounts for no less than 66%, the quality ratio between the calcium oxide and silicon oxide is nor smaller than 2.0. But many cement factories only do the strength experiment frequently.Clinker content in the cement. In the standard requirements, the total content of ordinary silicate cement clinker and plaster should be not smaller than 80% and be smaller than 95%. But now, many large cement factories produce cement which contains only 65%-70% clinker, not alone many small cement factories all over our country. Generally, the cement in the small cement factories only contains 50% clinker. The small cement can not be called cement and it only can be called mixture.
Testing methods. Cement is in the supervision and administration of the Technical Supervision Bureau and the spot check is done every year, which can not restrain the production of cement factories. The necessary check items of national testing standard is only strength, setting time and safety, along with some chemical index, which is far from enough. What’s worse, some kinds of cement which have been taken some measures can satisfy these requirements easily.

This fine stone concrete pump has characteristics of reliable system, low failure rate, easy to maintain and is the ideal concrete delivery equipment for fine stone.
This type of electric trailer concrete pump is especially applied to floor heating engineering which has large construction area and high efficiency.The reversing control is electric-hydraulic type. The electric part is controlled by PLC, which is reliable, more accurate with small impact. The main oil pump is under the famous brand of Kawasaki from Japan.Main electric elements are imported original Schneider, OMRON, Siemens, LG, etc. HAOMEI will briefly introduce some maintenance methods: ensure the machine temperature; reasonably control the pumping time and do not let concrete stay in the pipe too long; eliminate the concrete in the pump when moving it; clean the electric trailer concrete pump by hot water; take insulation measure for the pipe line of concrete pump if necessary.

The Structure Introduction of Haomei Concrete Pump

The important structure of concrete delivery pump is hydraulic pump. It can be divided into domestic hydraulic pump and imported hydraulic pump according to different origin. According to the different structure forms, hydraulic pump is composed of gear pump, vane pump and pillar-plug pump. Different forms of hydraulic pump can be used in different pressure grades.
Because of low cost and strong adaptability, gear pump is widely used in the trailer concrete pump manufacturers in the early time. However, because of the smaller pressure bearing and bigger impulse resistance, gear pump is often installed on the low pressure pump or used in the auxiliary oil passage system of medium and high pressure pump.Pillar-plug pump can be classified into oblique tray pillar-plug pump and oblique axle pillar-plug pump. It is very popular because of the wider adaptive pressure rang.
The main hydraulic pump of some low pressure concrete pumps adopts oblique tray pillar-plug pump, which improves the quality of the concrete pump for the high grade component configuration. The imported hydraulic pump is also oblique tray pillar-plug pump, which is world-class product. The domestic oblique axle pillar-plug pump is also high in quality. In fact, users can judge the quality of concrete pump performance from the grade of hydraulic pump.

Operating Procedures of Concrete Pump

Operating of Concrete Pump ,some matters needing attention in the pumping and maintenance of concrete pump.Operators can not maintain and repair the concrete pump until operators tuck the cantilever crane, cantilever crane has reliable supporting, the engine is shut down and outrigger legs are fixed.Before maintaining concrete pump, shut down the machine and release the pressure in the energy accumulator.If operators open the hydraulic lock of cantilever crane before fixing the relevant cantilever crane, it will produce some dangers of hurting people which are caused by the dropping of cantilever crane.Do not maintain and repair the concrete pump until the concrete pump is placed on the flat ground well and operators make sure that there is no unexpected move. When the pipeline of concrete pump is blocked, operators must release the pressure in the concrete delivery pipeline by anti-pumping and then they can disassembly disassemble the concrete delivery pipeline.In the operation process of HBT80 trailer concrete pump, do not open the hopper mesh, cover plate of water tank and other safety protection facilities. It is prohibited to put your hands into the hopper and the water tank, or use hands to grasp other moving components.When pumping concrete, operators must make sure that the concrete in the hopper is on the pedal shaft in order to avoid the concrete jetting which is caused by inhaling gases.

About Concrete Pump Some Matters in Special Weather

1. In the cold season, users had better wrap the concrete delivery pipeline with thermal insulation materials, which can prevent the concrete in the delivery pipe from freezing and ensure the temperature of casting concrete.
2. If the concrete pump should be operated in the hot season, it is necessary for users to cover the delivery pipe of concrete pump with wet cover and wet straw bag to avoid sun exposure.
3. When the horizontal delivery distance of electric and diesel concrete pump exceeds 200m, the vertical delivery distance of concrete pump is over 40m, the delivery pipe is vertically downward or the horizontal delivery pipe is placed before inclined pipe, and the unit cement dosage of concrete mixture is under 300kg/m3, operators must choose the reasonable piping method and pumping technology. It is appropriate to use the delivery pipe of larger diameter and longer conical tube, and use less elbow and hose.
4. When the concrete delivery height of concrete pump exceeds the biggest delivery distance, it is all right to use relay pump to pump concrete.
5. Check the abrasion condition of delivery pipe at regular interval to avoid the tube bursting, especially the elbow.

How to Solve Blockage of Concrete Pump

Concrete pump is usually applied to the concrete transportation work of tall buildings, highways, overpasses and other large concrete projects. Concrete pump consists of pumping machine and delivery pipe. It can be divided into piston, squeeze and pressure diaphragm type. The pumping machine is installed on the chassis and then equipped with placing boom, and then the concrete pump is equipped. Many users will have blockage troubles when using concrete pump, so how we can prevent blockage of concrete pump?
1:when installing and designing pipeline, we try best to avoid 90°and S-shaped curved which can reduce the resistance of pumping concrete and then prevent blockage phenomenon. The operation interval time of concrete pump is not too long, if the interval time is longer for some reason, it had better start the concrete pump or take anti-pumping and pumping several times for 5-10 minutes to prevent blockage phenomenon.2: the mix proportion of mini concrete pump should according to the requirements . Aggregate size must be selected to meet the requirements. Generally, it should not be greater than the diameter of 1/4 of the delivery.3:lubricate the pipeline with water before pumping concrete. Pump mortar firstly, and then is concrete which can avoid blocking.

About Opportunities for Rural Commercial Concrete mixer Market

Although commercial concrete develops rapidly in the city, After the farmers getting richer, the first thing is improving living condition and building new houses. Obviously, house building, town construction in rural area, new rural construction, roads and bridges need small concrete mixer.

In the past, the concrete is mixed on site .the operator takes it manually to the construction places. This on-site concrete proportion is difficult to control, the quality is no guarantee and there will have leakage accidents.

mini concrete mixer
Concrete mixer has many kinds and types, so it is difficult to find a suitable one.First of all, we must understand one point when choosing concrete mixer: good concrete mixer does not mean good quality and expensive price. As an old saying goes, the one that fits you is the best for you. Therefore, when choosing concrete mixer, we should confirm the different materials firstly. Some materials are dry powders, some are liquids, and some are hybrids. When you determine the material you need, you can narrow the scope. Secondly, we should have a good knowledge about mixing speed of concrete mixer. Certainly, the faster the mixing speed is, the higher its productivity is. Otherwise, the lower productivity will has bad effect on the project’s schedule.
