Pneumatic control system is used to control the weighing doumen, discharge doors, valves and other devices. Pneumatic control system of running state, will directly affect the production of mixing equipment accuracy and performance.

Pneumatic control system consists of a gas source, control components, the implementation of components and auxiliary components consists of four parts.

Source: is access to compressed air energy device. Its principal components are air compressors, cold-drying machine, storage tank, etc.

Control elements: to change the compressed air flow, pressure and flow rate to perform the compulsory components. Such as: electromagnetic valves, quick exhaust valve.

Actuator: a compressed air as medium to produce mechanical motion and the pressure of the gas can be converted to mechanical energy conversion devices. In this device, actuator main cylinder and double acting cylinders.

Auxiliary components: a compressed air cleaning, lubrication, noise and some equipment for components connected between phone calls. Auxiliary components include various air treatment components, gas piping, fittings and so on.
