Abstract: Based on the research on the grinding media motion in the ball mill, the discrete equation of grinding media motion about ball mill is established and the motion regimes of grinding media is simulated using the discrete element method (DEM) with simplifying the contact model of grinding media and rock material.
This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate. A variation in total ball angle can be detected and linked to grinding efficiency and charge expansion. This could help the operator to make the right decision and keep the mill
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and 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.
The ball mill abrasion test (BMAT) promises to offer accurate prediction of relative service lives of wearresistant alloys for liners and grinding media in mineral grinding environments.
