The Effect of Ball Size Diameter on Milling Performance

An investigation was conducted to determine the effect of the ball diameter sizes on milling operation. A laboratory size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 mono-sizes namely -8 mm +5.6 mm, -4 mm +2.8 mm and-2 mm +1.4 mm

The effect of ball size on breakage rate parameter in a

Jun 01, 2009 Ball size is a critical parameter influencing the performance of a ball mill, particularly for multi-compartment ball mills used in cement industry. Studies for selection of optimum ball size are reported in the literature (Tarjan, 1981; Duda, 1985). None of these studies is suitable to use in modelling and simulation studies.

Effect of ball size and powder loading on the milling

Dec 01, 2013 The effect of ball size on the particle size reduction has been investigated first for varying rotation speed of the container. Percent passing and size distributions of the milled Al 2 O 3 powder are shown in Fig. 1, Fig. 2, respectively, as a function of particle size for varying ball size.The average particle sizes (d 50) of the milled Al 2 O 3 powder are shown in Fig. 3 as a function of

Effect of ball and feed particle size distribution on the

Jun 01, 2018 Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used. If an objective function was to maximize the production of fines e.g. in the cement industry, the A.R shows that use of smaller ball sizes would give superior results.

How Ball Mill Ore Feed Size Affects Tonnage & Capacity

Jul 26, 2017 The effect of ball mill feed size and how it affects circuit throughput can be hard to estimate. Here we described a method of designing a crushing plant using power drawn and power rate to define reduction ratios in each stage of crushing. The plant power and power rates were computed from a Bond calculation as applied to the crushing plant

Variables in Ball Mill Operation Paul O. Abbe®

The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.

The effect of ball size on mill performance ScienceDirect

The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form
