Pebble mills are similar to ball mill except that the grinding media is closely sized suitably selected rocks or pebbles. The rotating drum causes friction and attrition between rock pebbles (say, quartz or quartzite pebbles) and ore particles. Pebble mill operates at low cost with respect to grinding media, power consumption and maintenance. It has wide application in gold mines.
The ball to charge ratio may be 5:1, 10:1, 15:1. This method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the discharge material is 4010 mm. The mill speed varies from 12 to 30 rpm. Planetary mill: High energy mill widely used for producing metal, alloy, and ...

Figure 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 The speed of rotation of the mill influences the power draft through two effects: the value of N and the shift in ...
In chapter 3 of this book I try to deliver basic information on material science, on the application of important figures and on the reliability of these figures. Chapter 4 of the book concentrates on rolls. Here we again have to consider the conditions of roll failures.
