Ore Structure Of Ball Mill

What is a Rod Mill with picture Info Bloom

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action An ore charge is added to the drum and as it rotates friction between the tumbling rods breaks the ore down into finer particles Although similar in operation a rod mill is often more effective than a ball mill as it requires lower rotational
