Kelsall et al (1959) were among the earliest to conduct experiments in the perfectly controlled environment provided by a computerized ball mill circuit simulator. They tested the general effect of various circuit design and operating variables, including circulating load ratio.

This paper presents a dynamic simulator of the electromechanical coupling start-up of a ball mill. The electromechanical coupling model based on the dynamic model of the ball mill, the characteristic equation of the clutch, and the dynamic model of the induction motor is established. Comparison between the simulation results of angular speed, load torque and current …

Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ...

This means that in operation, the pebble crusher remains in an intermittent operating state. The size of the ball mill is slightly undersized, which could explain why the circuit is unable to reach the designed product size (115 µm). Furthermore, the operating capacity of the ball mill has reached 90% capacity, running at near full load.

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
