Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …

And the motor realizes the operation of the ball mill through reducer. During the operation,the hollow shaft in the center of the ball mill drives the mill body to rotate under the driving of the power system. • Edge driving ball mill: the motor drives the gear on the edge of the cylinder through the reducer to drive the cylinder movement. 6.
We have a 11kV, GEC, 6.5MW motor which is connected via a gearbox and pinion to a ball mill. The motor is soft started by a LRS. About a year and a half ago, April and again now yesterday the mill has gone for a start and has sat there not turning. It has sat there pulling 1800A until the protection eventually triped.

Hello, I am looking to get into pyrotechnics and I was just wondering what type of motor I should get for my ball mill? What rpm for direct drive? Also, would I be able to wire the motor directly to my mains (230v AC)? I prefer to make things myself when possible, it's more fun that way so I was ...
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
