Mill Speed Control Using Programmable Logic Controllers

The paper handle a few topics from cement industry, such are: critical speed, mill speed control. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back. Therefore, this application conceived a PID controller for control the mill speed, using Programmable Logic Controllers.
