Procedure On Grinding Mill Sizing

Jan 08 2021 The transfer size will be 500 microns using a 12mm opening trommel. This can be true under special conditions of operation when treating fine ore at high mill density but in general the transfer size for such a trommel will lie in the range of 2 to 6 mm. Fine grinding in a SAG mill is less efficient than in a ball mill.

The ball mill rolls grinding media together with the ore as the ore grinds these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions with about 70 solid mixture in water. This procedure maximizes ore production and minimizes power consumption.
