Dec 12, 2019 how to choose a liner and ball for a ball mill. for a long time, a less accurate statement has spread widely, that is, the hardness of the grinding ball is higher than the liner by hrc 3 ~ 5. asked why, but nowhere to verify. there is no doubt that the liner and the grinding ball are in a cooperative relationship. they and the material together form a three-body abrasive.
Dec 15, 2020 method of balls rolling on ball- rolling mills is one of the most modern production methods. transversal rolling of balls from the round billet is economical. it differs from other methods due to the possibility to produce grinding balls on the uninterrupted automated aggregates, which allows 2 to 8 times to increase the output and 10-15% to.
Especially in wet grinding process of mine mills,there is large demand for forging balls. according to the material, forged steel balls can be divided into: c45 steel balls, 60mn forged steel balls, 65mn forged balls, 40cr forged grinding balls, 42crmo forged ball s and so on.the obvious advantage of forging steel balls is smooth surface, high.
Feb 01, 2004 there is considerable refinement of the carbide structure when the as-cast balls are heat-treated (fig. 3b). the amount of retained austenite following heat treatment appears somewhat reduced. the volume fraction of the carbides was estimated by image analysis to be 28% and 31% in the as cast and heat-treated medium chromium balls,.
