 · The number of turns will have a direct effect on the coil's d.c. resistance. A large resistance will decrease the current if the power supply is not changed. But if you build the coil first, and choose the voltage of the power supply second, then you can achieve any current you want. So I don't see a problem with resistance; just concentrate on ...

 · Ball mill is a common grinding equipment in concentrator, the main role is to provide qualified grinding products for the subsequent dressing process. The ball grinding process is a process in which the steel ball rotates in the cylinder at a certain speed and rises with the wall of the cylinder. After rising to a certain height, it will hit ...

Jan 01, 2017 In real milling operations, the number of ball mill turns is usually limited by an upper-bound value i.e. 88% of the critical turns. Usually, significantly fewer turns are …

Commonly 1:10 (material:wt. of ball) ratio is used. More rpm means lesser milling time but you have to check rpm limitation of your milling machine.

For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so …
