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.

Maintenance Matters for JS Series Concrete Mixer

1.Check if the seal chamber of shaft, import and export of distributor and the seal pipe are smooth, and check whether there is enough lubricant oil in every lubricating point and the gear box or not.
2.Check whether the oil in electric lubricating pump is used up or not. If it is going to be empty, add oil to lubricating pump timely. Do not operate the twin shaft concrete mixer without lubrication.
3.Clean the mixing drum completely. Besides, the materials in discharging door must be cleaned in time. And the remaining materials that can not be cleaned by water must be chipped away regularly.
4.The mixing blades of twin shaft concrete mixer must be adjusted weekly to prevent accidents.

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.

How to Maintenance the key parts of small concrete pump truck

Small concrete pump as the primary machinery of its construction machinery and equipment efficiently popular market, in the size of the project site can be seen in its presence. But for the construction work of high intensity, small truck with the increased use of time prone to various losses and failures, so weekdays maintenance is critical, especially the core components, critical parts of the maintenance is particularly important!
Small concrete pump truck as the current much welcomes the concrete construction machinery and equipment, which several key parts of the pump accessories should particularly pay attention to, such as manual grease pumps, lubricating oil cup, concrete pistons, arm, leg and so on weekdays to pay more maintenance. Now for several key parts of the maintenance work, each row of concrete were introduced:
Manual grease pump
After pumping before the end of each boot and you want to clean the vehicle, and then check and maintain grease filled manual grease pump storage tanks inside, pulling the grease pump handle, observe stirred bearing, S tube size spindle head place, if you can have a clean, grease overflows. In the course of their work should be pulled manually every hour on the grease pump handle 10 times. While maintaining a clean lubrication system to prevent dust and other contaminants from entering, do not contact with acid substances while working 500 hours each time cleaning the system.
cups oil lubrication
Two swing seat valve cylinders, each with a lubricating cup. Before pumping begins, it must fill up the grease into the oil cup and capping grease lubrication. Operation, should cap Lubricate every four hours, so that the spherical friction surface in good lubrication condition.
arm, leg and table maintenance
At the hinge point of the concrete pump truck boom sections, the four legs of the connecting shaft and bearing and turntable designed several positions butter mouth, usually required every 60 working hours to lubrication points (grease fittings) oil . It should normally be fully lubricated with grease until oil overflows.

How to dismantl of small concrete pump boom system

After any mechanical device used for some time, there will be some natural wear and tear, or inexplicable failures. This time if the following situations, you may need dismantling of small concrete pump truck boom system.
1, small truck boom maintenance is not good, the pin and the copper liner wear serious, we need to replace the pin or jib boring;
2, connecting rod or pin transformation;
3, the replacement of a new boom.
The first step: a small concrete pump can not work unless it is, on the contrary are otherwise removed from the beginning of the last boom, when installed in order. The final forearm flat on the ground, and with good wood pad, penultimate section arm and arm into the required angle of 5-10 degrees, in order to avoid arm cylinder in extended or retracted extreme position.
1.a small pump this last boom cylinder on the compression balancing valve is opened to relieve pressure. Because it is high-pressure oil, so the relief time to pay attention:
Loosen the balancing valve pressure regulator, the attention to the original position be marked, or write down Loosen laps. If you need to remove the balancing valve shall be installed with a cloth face balancing valve and the cylinder block, to prevent high pressure oil discharged wounding.Use a hammer to the boom cylinder and linkage pin knocked out, hanging under the fuel tank. If the pressure relief valve has been removed, be careful not to spill.
2.the arm and the link pin to knock them out, slightly lift the penultimate section of the boom, the last section of the boom for demolition is completed.
3.Remove the copper sleeve, copper sleeve and the pin to be checked, if you need to replace worn.
4.Install boom and cylinders, pay attention to the pin direction.
5.If you previously removed a balancing valve, now need to install and adjust the dynamic balance valve pressure balance valve on the fuel tank, the pressure to return to the previous setting.
6.Start and begin operating the boom, boom see whether the firm or have no oil spill situation. Note: When operating the boom, the smallest possible margin, no person shall close the boom range of motion.
After these few steps, you can successfully dismantling of small concrete pump truck boom system.
