23/9/2009· the ball mass and between th e ball ma ss an d the mill liners. The si ze reduction depends mainly on the surface are as of the media in interaction (Hukki, 19 54).
1/1/2016· A Bond ball mill work index is then performed on the mill product for the design of SAG-ball mill circuits. This is important because it was found that there was a 1–1.5 kWh/t higher ball mill work index if the –3.35 mm ball mill test feed size is obtained by SAG mill grinding compared with crushing.
Cylinder contains balls occupying 30–50 % of mill volume. Weight of ball is constant; Size depends on the feed quantity and diameter of mill. Working: At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce
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 for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted. It was
29/9/2015· Milling is a widely used industrial operation common for cases where size reduction of particles is required (Reid et al., 2008).It can also be known as grinding and involves the size reduction of particles smaller than 10 mm.There is a vast range of mill types available commercially and the choice of mill is based on a variety of factors, such as properties of the
One method of size reduction is the ball mill. The ball mill is a type of grinder that grinds materials into fine powder. When heavy balls of material fall on and crush the material being milled, grinding occurs. The raw material's particle size decreases as a result of continuous collision. The size and weight of the ball, as well as the
