Ball Mill Tight Gear

Industrial gear unit drive solution for ball mills SEW

A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls. The drive system can either consist of a central drive (central gear unit: helical gear unit or planetary gear unit) or

TECHNICAL How to Spec a Mill Gear Power & Transmission

Ball mills are smaller still and use a larger percentage of balls to perform most of the work. Large-di-ameter mills allow for use of gear ratios not normally thought possible in sin-gle-reduction applications — namely, 8:1 to 20:1. If the gear is to replace an existing gear, then manufacturing drawings or installation drawings complete with gear attributes, center distance and dimensions
