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.

Optimization of Grinding Parameters of Quicklime CaO at Different Mills
Ball load (35%), feed l oad (35%) and N c (70%) for conventi onal ball mill and ball load (50%), feed load (%) for vibrated ball mill were kept constant when grinding time experiments performed.
A simulation study of laboratory scale ball and vertical stirred mills ...
The sample below 3350µm (d80 = 2100µm) was ground in the laboratory scale stirred mill and ball mill. The d80 sizes of the products at the end of grinding periods of,, 1 and 4 min in the stirred mill were determined as 190, 102, 78 and 28µm, respectively. For this purpose, the stirred mill was used at a stirring speed of 360 rpm ...
Ball Mill RETSCH powerful grinding and homogenization
Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications. Cooling, heating cryogenic grinding.
A comparison of the Bond method for sizing wet tumbling ball mills with ...
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 ...
