A storage equipment of concrete batching plant-Cement silo

Cement silo is used for storage of bulk materials, however, concrete mixing plant is the equipment for producing concrete. People may think cement silo has nothing to do with concrete batching plant, however bulk cement silo and concrete mixing plant have great relevance, that is the bulk cement silo is one of the main equipments of concrete mixing plant.
The application of cement silo is not only in fully automatic concrete batching plant, it may be also used in cement manufacturing plant. The concrete batching plant for storing cement usually employs cement silo for cement silo, bin is currently the most suitable for concrete mixing station as the storage device, it has a good moisture-proof feature. Generally, small concrete mixing plant will equipped with cement silo of 50 tons or 60 tons. It is according to your specific construction, and there are cement silos ranging for 80 tons to 200 tons.

How to judge the qualification of commercial concrete batching plant

1.If the mixer of stationary type concrete mixing plant is self loading type, its radial runout of discharging buckle ring can’t exceed 1% of the diameter of the feeding port. What’s more, you should check the vibration sieve screen quality and the reasonable size of the screen mesh and sieve pore, and check the installation precision of screen mesh;
2.The transmission system operation of mini mobile concrete batching plant should be flexible, and there isn’t any abnormal noise;
3.The transmission of the belt conveyor, bucket elevator and cantilever dragline in concrete batching plant equipment should be stable and the operation should be flexible, the brake can be high, there isn’t abnormal noise and chain holder ;
4. The inspection of measurement system is also very important, you should check the sensitivity and accuracy of measurement system;
The feeding and discharging of measuring hopper should be smooth, and can’t appear phenomenon of accumulating material or overflow ;
6. The safety valve of stationary mini mix concrete batching plant can’t appear air leakage phenomenon; the quality of cement tank should be qualified; the matched line installation should be reasonable, and the installation of equipment should be right.

The mositure volume impact for concrete batching plant

We know that a certain proportion of concrete is made by mixing sand, cement, additives and water through a single large sand and gravel aggregate moisture or rain weather is higher, will be on the ready-mixed concrete batching plant to produce mixed concrete great impact, let’s look at the concrete mixing sand and gravel aggregate excessive moisture impact on what?
First, the impact is expected on the part of aggregate will cause the belt sticky material phenomenon, reducing the ratio of the amount of concrete aggregate, affect the quality of concrete.Second, the most vulnerable to the impact of sand moisture content of water is added to C30 concrete cementitious material per cubic amount of 400kg, water 180kg, 1800kg count the amount of sand, gravel moisture decrease 1-18kg, water-cement ratio will decrease about 10.By measuring the amount of water we should take some of the ways to reduce the moisture content of sand, we need the following:the stability of gravel sources;sand particle size distribution issue, different gradation, grain shape different moisture content;by strengthening the detection of the workability of concrete slump to reverse the deduction for moisture detection accuracy;for a known mixture ratio, if the machine and the test results in line with the case that the water content of the sand to be accurate;
through the sand and gravel processing and re-mixed, mixed with a lot of powder, to control the moisture content for concrete.The professionalism and technical personnel and operational personnel, appropriate adjustments based on experience.Any more about pan mixer concrete batching plant, pleae feel free to contact us.

the way to connect screw and cement silo

We all know that in the ready-mixed concrete batching plant equipment, cement is usually stored in a cement silo by screw conveyor transported to the mixer, in order to prevent leakage of cement, transport volume accurately, we must be prepared to understand and correct link screw and cement warehouse.
According to the division in terms of conveying the material displacement direction: screw conveyor is divided into horizontal and vertical screw conveyor screw conveyor two types.By the conveyor screw body, expected out and drive three major components, screw conveyor inlet and outlet connections cement silo into: ball joint flange rigid connection and hanging tarpaulins soft connection plus two forms. Visual equipment disassembly decide how often the interface forms.
cement tower mixing plant spiral with cement silo / cement concrete tank connection, before mounting body specially designed to enable normal operation within the helical axis force to pull, pull it from the front seat shoulder thrust bearings within the gear unit and in preventing hanging shaft seat pressure, to avoid the phenomenon of the bolt shaft by the sweep chamber pressure generated. After the installation is complete, to open each loop power switch, check whether it is normal, under normal conditions, the device does not work, conveyor running lights are not bright, inverter and other lights. Also note that all personnel not touch the screw conveyor moving parts, non-professionals are not free to contact the electrical components and control buttons.

Five gas path systems faults of mini mix concrete batching plant

In the actual operation process, The mini mix concrete batching plant will also have a variety of abnormal conditions. Only the correct use and maintenance of the system, the high efficiency and good economy of the production can be ensured.The common main five faults are as follows:
1. Air failure
The common fault of the air compressor is non-return valve damage, piston ring wear serious, air inlet valve damage and air filter is clogged.The pressure relief valve failure. Pressure is not high, the failure always is the pressure regulating spring breakage or rupture of diaphragm, and it must be updated.
2. Cylinder trouble
The buffering effect of the cylinder is bad, generally due to the buffer ring wear or the adjusting screw is damaged, you should replace the sealing ring and adjust the screw..The piston rod and the cylinder head damage, usually due to the eccentric rod installation or buffer mechanism does not work, you should adjust the center position of the piston rod in time, when necessary, you should also replace the buffer ring or adjust the screw.
3. The reversing valve fault
The reversing valve can not change or change slowly. You should check whether the oil mist device is working properly and whether the lubricating oil viscosity is appropriate.
4. Pneumatic auxiliary element failure
The adjusting amount of the mist device adjusting needle is too small, oil plug and pipeline leak can make the liquid droplets of oil can't be atomized, you should promptly dealt with the blockage and leakage, adjust the amount of oil drops make it achieves about 5 drops /min. In normal use, the oil surface in the oil cup should maintain in the lower range. The sediment water on the bottom of cup should be excluded in time.
5. Mechanical failure
In the powder metering hopper discharge mouth often appear that the material shaft droved by the air cylinder is stuck; the turning plate butterfly valve driven by the rack cylinder is stuck. This will make the close and open is not in place or not open. So you should often clear the powder agglomeration plate on the inner wall of the butterfly valve.
