Pneumatic feeding system package conveying control, weighing batching, material mixing control, packaging and other equipment automation control, to provide a complete control scheme, integrated touch display, production management, weighing sensor collection and processing, loading and unloading, alarm output and other functions, one weighing instrument can meet the user control production requirements, high integration; The dosing module provides all functions except touch display and production management, and completes control with man-machine interface; The weighing sensor mainly collects the weight signal of the packaging scale, and transmits the output to the PLC after internal filtering processing, and the PLC completes the other control parts.

The design principle of the pneumatic conveying system is to use the dynamic and static pressure of the air to make the material particles suspended in the air flow or transported along the pipeline. The material and air enter the spiral pneumatic separator in the form of gas-solid two-phase flow. In the separator, the material is separated from the air flow, and the material falls into the bottom Feeder through the air closing device, and the air flow enters the fan through the suction port. Then using the air flow with a certain pressure and speed generated by the fan at the air outlet, the material and air form a gas-solid two-phase flow at the bottom feeder again, and are transported by the pipeline to the discharge device for output.
