Abstract The theory of the calculation of the size distribution of the equilibrium mixture of balls in a ball mill is developed. The differential equation is solved for wear laws of the form wear rate per ball ∝ r2 + Δ where r is ball radius. Δ = 0 gives the Bond wear law and Δ = 1 gives the Davis wear law. Methods of determining Δ are illustrated. Experimental data are presented which.

A mathematical model able to predict the cooling rate of wire rods in an EDC conveyor, taking into account opera-tion parameters, cooling conditions and other inherent process parameters, has been developed. This model in combination with an austenitic and microstructural model will enable to produce important quality and productivity beneﬁts.

We model the dynamics inside the ball mill in dependence of the lling volumes of suspension and balls (cobalt) takes place in a so-called \ballmill . In this case it is a rotating cylinder at 150 cm length and 80 cm diameter shown in Figure 1.1, having The aim of this project is to nd a mathematical model for the movement of ball-.

In this paper, the milling parameters of high energy ball mill (Fritsch Pulverisette 7) like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method (DEM) provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.

During the mill’s maintenance stop of a crushing and grinding plant, the ball bed for two mills was unloaded with its 25 tons for unit 1 and 39 tons for unit 2 of alumina balls. The mill’s inner diameter D (usable diameter) is 242 cm and the mill’s inner length (usable length) is 650 cm. Fig. 1 shows.
