The schematic layout of a cement milling circuit is shown in Fig. 1. The mill is fed with raw material (feed). After grinding, the material is introduced in a high-efficiency classifier and separated into two classes. The tailings (refused part) are fed back into the mill while the finished product (accepted part) exits the milling circuit.
The first part of the paper describes how the structure of the fuzzy controller for a cement mill, an important part of the closed loop of the cement grinding circuit, is designed [1]. The second part presents the design of a control system by using PLC for clinker grinding circuit together with the application of a PLC program and its simulation.

Ball Mill Working Principle. To be chosen according to the grinding material, material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body, when the ball mill cylinder rotation time, grinding body due to inertia and centrifugal force, the effects of friction, making it attached to the cylinder liner on the cylinder body away, when taken to the height of a ...
Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to. maximise productivity and minimise operating costs.
Several intelligent controllers designed based on fuzzy logic [13] [14][15][16] for the cement ball mill grinding process were able to track the setpoint and reject the disturbance better than the ...

Grinding machines are powerful and designed to operate at high speeds. If a grinding wheel shatters while in use, the fragments can travel at more than 300 miles per hour. In addition, the wheels found on these machines (abrasive, polishing, wire, etc.) often rotate at several thousand revolutions per minute. The potential for
Cement raw material has been almost exclusively ground in roller mills (vertical air-swept grinding mills) since the sec-ond half of the 20th century.
