A Study of Charge Motion in Rotary Mills, with Particular ...

grinding does not take place by rotary nipping of the ore between the balls. The balls spiral in and out of the charge in a way that implies good mixing of the charge. The actual centre of mass of the charge was determined, and was found to provide the correct form of the torque curve when the simple torque-arm method of calculation was used.
