You can learn to operate cement bulk semi trialer one step by step here.
Cement bulkers are more and more popular in African and South-east Asia market now.As we all know that Bulk cement is usually delivered and transported in specially constructed vehicles to cement plant, cement warehouse, or large construction site. To serve this bulk transport purpose, we have designed the bulk cement tank semi trailer, which is now covered by the Chinese utility model patent.
So if you want to own your own cement bulkers,you should learn the items carefully which would help you to improve effiency.
How does cement bulker work?
The working principle of cement bulker is that the engine transmits power to the air compressor through the transmission device, compressed air enters the tank, and the powder material is fluidized through the fluidized bed.
When the pressure reaches 0.2Mpa, due to the pressure difference between the inside and outside of the tank, the powder materials are transported along with the air to the designated position outside the tank through the discharging pipe. Fast discharging and low residual ash rate are the advantages.
1. Open the pressure relief valve first and discharge the remaining compressed air in the tank.
2. Open the filling manhole cover and place the filter.
3. Start loading cement into the tank.
4. After loading, wipe off the cement on the sealing ring and then cover the manhole cover tightly.
5. Close the pressure relief valve, check the valves such as the discharging butterfly valve to prevent cement leakage during transportation.
How to discharge the cement trailer?
1. Connect with the discharge pipe, put the sealing ring when connecting with the discharge pipe. Open the front and rear air inlet valves. Close the pressure relief valve, external air source valve, secondary blowing valve, and discharging butterfly valve.
2. Start the engine smoothly, so that the air compressor can start smoothly at low speed. Then gradually increase the throttle to make the air compressor reach the rated speed and inflate the tank.
3. When the pressure rises to about 0.15MPa, open the secondary auxiliary blow valve to clear the discharging pipe, make sure that the discharging pipe is not blocked, and then close the secondary auxiliary blow valve.
4. When the pressure rises to 0.2MPa, open the discharging butterfly valve to start discharging.
5. When the pressure drops to about 0.02MPa and becomes stable, the cement in the tank is almost fully discharged and the warehouse is started to be cleaned.
6. Close the front air intake valve and just make the rear air intake valve work. Observe the pressure gauge. If the pressure rises, it indicates that there is still residual material at the rear of the tank. After the pressure rises and then falls back to and keeps about 0.02MPa, it indicates that the rear part is unloaded.
If the pressure does not rise again, the rear part has been discharged. After confirming that there is no material left at the rear of the tank, open the front intake valve, and close the rear valve to clean the remaining material at the front of the tank. Similarly, observe the pressure gauge.If the pressure value rises, it indicates that there is still material in the front of the tank. When the pressure rises and falls to and keeps at about 0.02MPa, it indicates that the front is cleaned. If the pressure does not increase, there is no material left in the front.
7. After confirming that there is no material left at the front or the rear of the tank, turn off the engine, stop the air compressor, open the pressure relief valve, close the discharging butterfly valve, remove the discharge quick connector, and return the discharge pipes to the vehicle. Finish unloading.
