Control Philosophy For Ball Mill

Modelling and Control of Ball Mill Grinding

Feb 17, 2018First of all since the process model unavoidly changes with time, it must be estimated by adaptive methods such as it is in self-tuning controllers.

Process Control of Ball Mill Based on MPC-DO

Jul 26, 2021Furthermore, a compound control strategy for process control of the ball mill is proposed to describe the grinding process precisely where disturbances exist. It consists of two types of controllers—a feedback regulation component based on MPC and a feed-forward compensation component based on DO.

Control of ball mill grinding circuit using model

Apr 01, 2005the wide acceptance of these control schemes in the process industry can be traced to the following salient features of these schemes: (1) relatively easy to tune, (2) straightforward extension of predictive controllers for siso processes to mimo processes, (3) explicit use of non-linear models to design the controller, (4) ability to handle the

The Control philosophy controlled to a mill load set-point by automatically adjusting the ore feed rate, and the acoustic control controlled the mill speed. This is all a commissioning exercise and one of the things we wanted to do was incorporate an additional loop whereby mill speed is automatically adjusted to control mill weight/load.
