Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance.
Ball Mill and Grinding Circuit Preparation for StartUP The following items must be checked before the equipment in the Grinding Circuit is started. Check the ore slot feeder for obstruction or hang—ups. Check the ball mill belt feeder for undue buildup of material. Check oil level in ball mill lube oil tanks. Also, check grease level in the mill ring gear spray lube drum.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Ball milling is one of the few unit operation that improves with increasing mill diameter. If acceptable results can be obtained with a 12" jar mil, then good result will certainly be obtained with a 72" diameter mill. Of course there is the possibility of over milling, obtaining a different particle size distribution or a need to change ...
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.
