Effects Of Grinding Media Shapes On Ball Mill Performance

Dec 27, 2021 The aim of this study is to evaluate the effect that the size of grinding media exerts on ferronickel slag milling efficiency and energy savings. A series of tests were performed in a laboratory ball mill using (i) three loads of single size media, i.e., 40, 25.4, and 12.7 mm and (ii) a mixed load of balls with varying sizes. In order to simulate the industrial ball milling

The ROM UG2 ore sample was crushed using a cone crusher, and screened to produce ball mill feed with 100% passing 1.7 mm. A 30.5cm 30.5 cm laboratory scale cylindrical ball mill was used for the grinding experiments. 4 kg ore was used for grinding and flotation tests. Grinding was performed in the

Abstract The effect of grinding media on milling kinetics has been generally studied using one media shape. However, very little work has been done on investigating mixtures of media shapes. Combining different grinding mechanisms in term of contacts, the volume of grinding zones can be efficiently increased when there is an optimal mixture of two or more grinding

absence of a performance parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change. • Population balance modelling

Lameck (2005) –The effects of grinding media shapes on ball mill performance (MSc thesis –University of Wits) Balls Worn Cylpebs balls Lameck’s work indicated that: • Higher torque (power draw) can be achieved with increased packing efficiency –particularly for worn ball media • At lower mill speeds, the cylpebs and new media draw

An increase of over 10% in mill throughput was achieved by removing the ball scats from a single-stage SAG mill. These scats are nonspherical ball fragments resulting from uneven wear of balls with included porosity. 30t of scats were removed from a total charge load of 70t. Surveying and modelling the mill revealed that the breakage rates had increased dramatically
