1. Introduction. A ball mill (Figure 1) is the key piece of equipment for secondary grinding after crushing and is suitable for grinding all types of ores and other mill are used in the mining, cement, chemical and agricultural industries, particularly tumbling ball mills [1,2,3,4].The comminution process is dependent on the rotation of the mill to lift the grinding media for ...

Thus, the breakage rate of a fullscale mill is higher at the smaller sizes because there are more grinding media layers present in the bulk of the charge in fullscale mills . McIvor [25,26] pointed out that the material's size distribution going through the ball mill was much coarser at a high CLR than at a low CLR.

Fig. 2 shows the timewise evolution of the cumulative PSD experimentally obtained from the laboratory batch ball mill with different single ball sizes (, d B = 20, 30, and 40 mm) using steel balls and alumina balls. As milling progressed and finer particles were generated by breakage, the PSD shifted to the left monotonically even in the fine particle size domain (1100 μm).

The optimization of processing plants is one of the main concerns in the mining industry, since the comminution stage, a fundamental operation, accounts for up to 70% of total energy consumption. The aim of this study was to determine the effects that ball size and mill speed exert on the milling kinetics over a wide range of particle sizes. This was done through dry milling and batch grinding ...

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. Different materials are used as media, including ceramic balls, flint pebbles ...

A tracer pulse is injected at the mill inlet and the concentration of the tracer is measured at the mill outlet. Although the RTD data clearly indicate that finite axial backmixing takes places in many continuous opencircuit mills [18,2325], many researchers assumed idealized mixing regimes,, perfect mixing [2629] or plug flow [7,12,30,31], for the sake of simplicity in their ...
