Committed to helping customers improve material quality and production efficiency The vacuum conveyor generates negative pressure from the RF generator,so that the vacuum conveyor will suck the material into the silo from the storage tank through the suction pipe,and then separate the gas from material through the filter,and the feeding time is controlled. When the suction is completed,the pneumatic opening mechanism opens the door to place the material into the relevant equipment,the backflushing device removes the powder adsorbed back to the filter,and then closes the discharge door,and the next cycle begins. FINE SIEVING MACHINE 1.Suitable for many industries such as medicine,foodstuff, chemical industry,metallurgy and building material 2.Aiming at the confinement transportation of various powder 3.Improving the cleanliness of materials,which can meet the diversified transportation needs of different customers
