Abstract:

Aiming at the current situation of flotation, dosing completely rely on experience by hand in the coal preparation plant, to design a floatation automatic dosing expert system. The expert system can be realized that dosing completely done automatically by the controller PLC according to the real-time condition, at the same time via the touch screen and the host computer for real-time data monitoring and recording. After the running of the system to reduce drug consumption, reduce labor intensity, improve fine coal productivity .The system has overall effects.

Key words: Floatation automatic dosing, Expert system, PLC, The touch screen
