Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and ...

THE OPTIMAL BALL DIAMETER IN A MILL

2010; 2011). For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both cases, the specific power consumption increases and the grinding capacity decreases (Concha et al. 1992; Katubilwa and Moys, 2009; Erdem and Ergun ...

01/09/2013  The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles. Therefore, it is a common practice in industry to use a mixture of balls rather than balls of a single-size to ensure the ...

Effect of ball size and powder loading on the milling ...

01/12/2013  The ball diameter of 5 mm is optimal at 50 rpm of rotation speed (the resultant average particle size of the milled powder is 2.3 μm), ball diameter of 3 mm is optimal at 100 rpm (1.4 μm), and 2 mm is optimal at 153 rpm (0.84 μm). From this result, it can be said that the optimal ball size for efficient milling decreases with the rotation speed of the mill.

at which optimum size reduction takes place, is determined in terms of the percentage of the critical speed of the mill [8]. The critical speed is the speed at which the mill load sticks to the walls of the mill during rotation. The aim of this project was to determine the effect of the ball diameter on the operating parameters of the mill, which included the energy efficiency, the power ...

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...
