TECHNICAL NOTES 8 GRINDING R P King

Overflow discharge Wet Figure 8 5 Effect of mill filling on power draft for ball mills The data is taken from Rexnord Process Machinery Reference Manual Rexnord Process Machinery Division Milwaukee 1976 The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 8 4

Wet overflow ball mill

The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery Materials are put in cylinder through the feed opening and then thoroughly grinded The falling course of iron balls and ores can produce huge falling impact and autogenous grinding It is a high technological enterprise that integrated research

What is a Rod Mill? (with picture)

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

Overflow Ball Mill Ball Milling Method Principle of Ball

Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable proportion Driven by the transmission device the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and
