What S The Difference Between Sag Mill And Ball Mill

nov 26, 2019 the working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize. sometimes, in order to improve the processing capacity of planetary ball mill working principle. planetary ball mills consist of several cylindrical grinding jars which are filled with loose grinding balls. two superimposed rotational movements move the grinding jars: like in a planetary system the grinding jar rotates on a orbit around the centre.planetary ball mills are used wherever the highest degree of fineness is required.in addition to well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying.the extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and mar 10, 2021 wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of dry ball mill. the grinding particle size is fine and uniform, and the wet ball milling can not only grind agglomerate into fine particles, but also mix the lean material and the plastic material well.
