coarse material back to the grinding mill for further comminution The Overflow Discharge mill is best suited for fine grinding to 75 106 microns The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns
MOYSM The grind size varies according to mineral type and orebody but would typically be down to a P80 of 45-20 micron i e finer than that for conventional ball milling but slightly coarser than ultra-fine grinding
I am working in a plant with single stage grinding using a ball mill we operate the mill power at around 1400KW& the feed size is 20mm The measurement used are: the mill filling volumethe discharge rate of the millthe discharge density of the milland the first time derivative of the discharge density
