In the light of the conditions and a series of cement manufacture, design a kind of cement automatic batching system based on PLC. The system by Siemens S7200 models of PLC as measurement and control core, Siemens SM420 inverter as speed regulating device, constant feeder is adopted as a weighing device, rotary encoder as speed measuring device, etc. Adopting fixed time gathering weight and speed, and the PID adjustment, cement production can be implemented online dynamic weighing and adjustment, to enhance the antiinterference.
