The Rod Mill is a grinding mill used for coarse grinding or fine grinding, which offers the following types and uses. 1) Peripheral Discharge Type. 1. Wet grinding type ( type and type) This type of mills is used to produce products of relatively coarse particles such as fine aggregate for concrete ( sand making).
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Apr 09, 2015· Generally for harder materials, specialized and expensive type of grinding mills are used. In addition if a particular mill can be used over a range of hardness scales, the harder the material the lower the throughput for a given size requirement. ... or through the far end of the mill (trunnion discharge).
The CIW is a Small Ball Mill that''s belt driven, rigid bearing, wet grinding, trunnion or grate discharge type mill with friction clutch pulley and welded steel shell. The 7 and 8 foot diameter mills are of flange ring construction with cut gears while all other sizes have cast tooth gears.
Outotec® MH Series Grinding Mills offer a costeffective, and easy to operate and maintain grinding solution across the mill lifecycle.

The first step in slag processing is size reduction to liberate metallic iron and ironbearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80% Fe (Shen and Forssberg, 2003).
