Amit Lesson Ball Mills Amp Circuits Mining Mill

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.application of value engineering techniques to grinding process modelling led to the identification of two basic functions of the ball mill-classifier circuit. In terms of a specified circuit product size which is used to differentiate between coarse or oversize material and fines or undersize material, these basic functions are breakage of the coarse material and removal
