steel ball consumption for sand milling

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

I know of a practice that uses 50 percent of the theoretical consumption calculated by the Bond formula for ball mills; for S Mills 65 percent of the theoretical consumption is used considering the S mill as a ball mill.The rotating paddle used in the Bond Ai test is made of SAE4325 steel hardened to 500 Brinell and therefore not necessarily equal to the hardness and abrasion resistance of ...

How to Reduce Steel Consumption in Grinding Mills

In the tumbling mills (autogenous, semi-autogenous, rod and ball) wear is generally expressed in terms of steel consumption per ton of ore ground or per kWh consumed by the mill. When comparing the wear rate of different ores in different types of mills, unit weight/kWh is considered a better measure. The steel wear or loss is a net result of the loss due to mechanical wear from impact ...

Ball Milling Material Milling, Jet Milling AVEKA

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by both impact and abrasion. In ball milling, the ...
