Consumption of steel grinding media in mills – A review
Pintaude et al. (2001) have considered the effect of particle size on the abrasive wear of high-chromium white cast iron mill balls. They have concluded that the ratio of steel ball to particle size is the critical factor. The highest ball wear rates occurred during grinding of fine granite under dry (120 mg/cycle) and wet (129 mg/cycle) conditions
How to Choose the Right Types of Ball Mill for Your …
A ball mill is a cylindrical device that rotates around its axis, partially filled with the material to be ground plus the grinding medium (usually ceramic balls, flint pebbles, or stainless steel balls). As the mill rotates, the grinding media crushes and grinds the material against the inner surface of the mill chamber, creating a fine powder.
The cement mill
Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with different ...

The first attempt of applying ceramic balls in industrial tumbling mill
The ball motion in the mill was simulated via discrete element method (DEM). Our results show that steel balls achieved faster breakage of clinker into finer particles than alumina balls, which was explained by the higher total–mean energy dissipation rates of the steel balls. The PSD became finer as smaller balls were used.
