The operating principle of theball millconsists of following steps. In a continuously operatingball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...

Working Principle &Operation. The apparent difference in capacities between grindingmills(listed as being the same size) is due to the fact that there is no uniform method of designating the size of amill, for example: a 5′ x 5′Ball Millhas a working diameter of 5′ inside the liners and has 20 per cent more capacity than all otherball millsdesignated as 5′ x 5′ where the ...

Ball Mill Operation.Ball millsride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive themillthrough 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.

1 Calculation ofball millcapacity. The production capacity of theball millis determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of theball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
