Feb 17, 2018· Modelling and Control of Ball Mill Grinding. Dynamic experiments were performed in a continuous open-circuit 40×40 cm ball mill using a pseudo-random binary sequence of the feed rate and measuring the variations of the discharge particle-size distribution. The impulse response is calculated by a cross- correlation technique.

Feb 13, 2017· CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
Aug 02, 2010· Aug 02, 2010· A fuzzy controller was designed for the control flow rate inside the ball mill to avoid overfilling or emptying the mill [34]. The fuzzy system was used to optimize the ball milling circuit [35] .
The ball mill grinding device control system in accordance with the teachings of the present invention prevents overloading of the ball mill because the recycle rate is not allowed to become greater than desired, such that the ball mill is not permitted to choke and in effect it permits the ball mill circuit to operate much closer to its ...

Ball Mill Control (3 replies and 2 comments) I think, you must continuously check the draw point of ball mill and set this to the set point by changing the feed rate and Keeping the feed pulp 70% percent solid. Electicial power، set this as set point to 80%-85% nominal power of electromotor.
Apr 25, 2016· The two types of ball mill in general use are the grate mill and the open-end mill. Most manufacturers make both kinds; the difference between them is that the grate mill has a steel grid clear across the discharge end, but the open-end mill has only an open trunnion at the discharge end, through which pulp flows freely.
