motor selection for ball mill Forum for Electronics

Mar 09, 2016 Lets get back for the motor selection So induction motors should be the target here. I can get fan motor or water pump motor (2 poles) with 2900 RPM. should I use a pulley to reduce the speed by factor of 3 = 966 RPM ( triple the torque and quarter the speed) and then use the circuit in my previous post to fine tune the speed ?

Ball Mill Motor Power Draw Sizing and Design Formula

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.  Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers

Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
