How to design a Ball Mill

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.

of the ball mill would be of great interest. Accordingly, the aim of this paper is to identify which dimen-sionless numbers must be kept constant in order to reproduce the results obtained in a laboratory ball mill at the industrial scale. Such scaling criteria are provided by an exhaustive dimensional analysis applied to the ball mill.

Ball Mill

The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.

Model-based procedure for scale-up of wet, overflow ball mills …

This method is incompatible with computer modelling and simulation techniques. It might not be applicable for the design of fine grinding ball mills and ball mills preceded by autogenous and semi-autogenous grinding mills. Model-based ball mill scale-up methods have not been validated using a wide range of full-scale circuit data.

Several mathematical models have been developed to predict the PSDs of particulate materials, including log-normal, logistic, Gates–Gaudin–Schuhmann (GGS), and Rosin–Rammler (RR) distributions, while truncated size distributions can also be used when a particle population would have every particle smaller than a definite top size [38, 39].In …

Grinding Ball Design

Ball Design Factors Size and Mass. Importance of size: Taggart (1927) stated "Size of balls should be proportional to the work to be done, i.e. the size of the particle that must be broken by impact, hence coarse feed and hard ores require larger balls than finer feeds and softer ores." The 9 to 10 m (30 to 33 ft) SAG mills now in …
