### Effect of Grinding Media on Milling

The size distribution of the balls in the mill charge appears to have no significant effect upon the size distribution of the product, nor upon the rate of grinding, provided that the size distribution of the balls is not too unreasonably chosen.

### Grinding Media - 911Metallurgist

Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill.

### EFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL …

2.3.2 Media size. The efficiency of grinding depends on the surface area of the grinding medium. Grinding in a ball mill is effected by contacts between ball and ore particles. The angle of nip is important and ball sizes must be carefully chosen in relation to the largest and hardest particles in …

### THE OPTIMAL BALL DIAMETER IN A MILL

The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both cases, the specific power consumption increases and the grinding capacity decreases (Concha et al. 1992; …

### 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.

### Comparison of grinding media—Cylpebs versus balls

The two grinding media have diﬀerent surface area, bulk density and contact mechanisms in grinding action. Comparative tests were conducted using the two types of grinding media in a laboratory Bond ball mill at various conditions of equality such as media mass, size distribution, surface area and input speciﬁc energy.
