The MODSIM® ball mill model is an encapsulation of the scaleup procedure by Austin et al. (1984). It is used when the selection function and breakage function parameters have been determined from laboratory batch tests. In addition to this, the dimensions of the fullscale mill should be available. This is indeed the case in the present work.

RSG Inc supplies dry ball mills in the range of 5 HP (3 Kw) to 5500 HP (4200 Kw). Dry ball mills are effective grinding systems in the general range of 500 microns down to 5 microns. Continuous milling systems are generally used in closed circuit with an air classifier. These ball mills are normally used in closed circuit milling in conjunction ...

The Bond ball mill work index is an expression of the material's resistance to ground and a measure of the grinding efficiency. The test is a standardized methodology that ends when a circulating load of 250% is obtained. In this paper, a new method based on the Population Balance Model (PBM) is proposed and validated to estimate the results ...

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 ...

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).

Some larger industrialscale ball mills can process up to 50 tons of material per hour. However, it's important to note that the processing capacity will also depend on the specific design and features of the machine, as well as the skill and experience of the operator.

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 ...

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.
