Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right). Both wheels rotate in the same direction, but at much different speeds. The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality.
This material is the feed for the grinding mill. Grinding. In this process stage, the crushed material can be further disintegrated in a cylinder mill, which is a cylindrical container built to varying lengthtodiameter ratios, mounted with the axis substantially horizontal, and partially filled with grinding bodies (, flint stones, iron ...
