ZKS Series Vacuum ConveyorA vortex air pump is used to extract air, creating a certain negative pressure at the inlet of the suction nozzle and throughout the entire system. Powder and granular materials, along with external air, are drawn into the suction nozzle, forming a material-air flow. This flow passes through the suction pipe and reaches the hopper, where gas-material separation occurs. The separated material then enters the receiving equipment. The feeding and discharging processes are carried out through the continuous opening and closing of pneumatic directional valves, which are controlled by a control center. The vacuum conveyor is widely used in industries such as pharmaceuticals, food, and fine chemicals.
