EFFECT OF BALL SIZE DISTRIBUTION ON MILLING
Dec 24, 2012 Ball mill – Wikipedia, the free encyclopedia. A ball mill is a type of grinder used to grind materials Laboratory scale ball mill. There are many types of grinding media suitable for use in a ball mill, More detailed
In this research, the effect of ball size distribution on the mill power draw, charge motion regime and breakage mechanism in a laboratory ball mill was studied using the discrete element method (DEM) simulation. The mill shell and crushing balls were made of Plexiglas and compressed glass, respectively. Modeling was performed using Particle Flow Code 3D (PFC3D).

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
