Rod Mill & Ball Mill Manufacturer & Supplier of Grinding Mills
rod mills 1/1800 ball mills, grate discharge 1/1200 ball mills, overflow type 1/1470 pebble mills 1/1200. W for rod and ball mills shall be taken as the weight of the rod or ball charge, i.e. the weight of the pulp is to be ignored. For pebble mills therefore W is to be calculated on the basis of the bulk weight of the pebbles.
Grate Discharge Advantage & Benefits
As secondary ball mills are usually fed a relatively (compared to SAG mills) fine F80 and have high re-circulating loads and produce product fineness of the P80 - 100 to 160 micron range, fitting a grate discharge needs to be carefully considered.
