The working principle of vacuum quantitative conveyor

The vacuum conveyor uses a vacuum pump to pump air, so that the inlet of the suction nozzle and the entire negative pressure state, the powder and granules are sucked into the nozzle along with the outside air, forming a tube to reach the hopper, and the gas and material are separated in the hopper. The separated material enters and discharges by continuously opening and closing the pneumatic reversing valve, and the pneumatic reversing valve is controlled by the control center. During this process, the materials are into this weighing hopper, and then weighs the whole. In the process of stably conveying the material by the quantitative screw doing below, the speed sensor and the load [...]
