Fine Sand Grinding Rod Mill With Powder Discharging From Middle Of Ball Mill

Grinding Solutions are currently running extensive flotation trials on a base metal project, where the Rod Mill is running a rod charge rather than a ball charge. This is done in order to better simulate the particle size distribution of a ball mill in closed circuit with a hydrocyclone in a continuous plant scenario.

A rod mill consists of a hollow cylindrical shell that rotates about its axis, similar with ball mill. It is partially filled with balls that can be made in chrome steel, stainless steel, rubber or ceramic. The inner part of the shell is usually lined with an abrasion-resistant material such as manganese steel or rubber.

Rod mill Features

1 Rod mill can be used as the fine crushing equipment to replace short-type cone crusher when crushing soft ores. It has a simple configuration, less costs and low dust pollution, which can save a lot of investment in dust removal machines.

2 When the tungsten ore, tin ore or other rare metal ores are selected by gravity separation or magnetic separation, rod mill is often used to prevent over crushing.

3 In the two-stage grinding process, rod grinding machine is generally used as the first grinding equipment, which has the advantages of larger production capacity and higher efficiency.
