# Tumbling Ball Pebble Rod Mills :

### Selection Of Rod Mills, Ball Mills, Pebble Mills And ...

Grinding media can be the ore itself (autogenous grinding -- primary and secondary), natural or manufactured non-metallic media (pebble milling) or manufactured metallic media -- steel rods, steel or iron balls. This chapter will discuss general mill design and the specific design and application of the following types of tumbling grinding mills.

2016-10-19 The most common types of tumbling mills are the rod-, ball- and autogenous mills. Depending on the type of ore, there are different charge media to be used. In rod and ball mills, the different charge media are usually made of steel and added to the mill. In autogenous mills, the ore itself is used as charge medium.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

This report presents the results of an investigation of comminution in tumbling mills. Five topics involved with ball- and rod-mill grinding kinetics were studied, and the results were analyzed in terms of phenomenological size reduction and transport models. Continuous rod-mill grinding was found to be characterized by high peclet numbers that permit simulation to be carried out by several metho
