Mathematical model of ball wear in grinding mills I.

1986-3-1 · For the ball charge in a tumbling mill, we will consider only one internal co-ordinate, the ball size d, and will identify the volume V with the actual ball charge volume. We will assume no fracture of balls in the mill, that is, R = 0. Define the new variables.

Simulation of a ball mill operating with a low ball

Ball charge sampling. The ball charge of the industrial ball mill was sampled during one of the maintenance stops. The mass of balls required to consider the sample representative was too high and it was not possible to achieve the necessary mass. The sampling showed many balls with different shapes as shown in the Figure 1. Breakage function parameters

Exploring ball size distribution in coal grinding mills

2014-5-1 · The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the mill capacity and the milling efficiency. Small balls are effective in grinding fine particles in the load, whereas large balls are required to deal with large particles of coal or stone

Ball mill factors

Ball mill that works on the principle of impact is an efficient technique of size reduction through grinding. The size reduction is an important factor for many industrial applications as this process is carried out to increase the surface area, to intimate mixing and to improve dissolution rate, solubility, binding strength and dispersion properties.
