Converting A Ball Mill From Overflow To Grate Discharge
Jun 23, 2020 Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until ...
Axial Transport In Dry Ball Mills Core
The simplest way to simulate a discharge grate in a at ended mill is to make this permeable to particles below a certain grate opening size G. Such a grate is 100 ecient in that all nes that reach the grate imme-diately exit the mill. This is, of course, not the case for real mills, but it is a reasonable starting point for study-
