Locked Charge Starts And Your Grinding Mill

Sag and ball mills with grate discharge are not prone to locked charge events because of the high amount of rocks and balls compared to fine ore. the pulp dischargers of a sag mill continually pump the finer material out of the mill, lowering the total amount of residual fine ore and thus improving the situation in respect to locked charge.Sag milling extends itself to many applications due to the range of mill sizes available. they can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. sag mills are also an optimum solution for wet grinding since crushing and screening in these.
