The extremely high centrifugal forces of planetary ball mills result in very high pulverization energy and therefore short grinding times The PM 400 is a robust floor model with 4 grinding stations You may also be interested in the High Energy Ball Mill Emax an entirely new type of mill for high energy input The unique combination of high
The grinding charge in a ball mill consist of cast or forged steel balls these balls are fed together with the feed and consequently ball mills can be in operation for months without stopping the ball size is often in the diameter range of 2075 mm the biggest size is chosen when the mill is used as a primary grinding mill More Details
Chromium alloy is the main composition of casting steel ball with diameter of 6 mm to 140 mm According to different chromium content the grinding ball can be divided into three kinds namely low medium and high chromium balls The hardness of relevant balls are HRC45 HRC50 and HRC58 respectively with diameter of 6 mm to 140 mm
Apr 11 2017 In the previous article we considered the method for determining the bulk weigh of new grinding media Determination the grinding balls bulk weigh directly operating in a ball mill becomes necessary on practice It is done in order to accurately definition the grinding ball mass during measuring in a ball mill and exclude the mill overloading with grinding balls possibility There are two
