Nov 18, 2008· Fig.1 Manhole of batch ball mill • Batch ball mill : The balls as will as the feed are charged through an opening in the lateral wall and discharge is through an opening just opposite to the charging manhole. In case of wet grinding the discharge opening is fitted with a …
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
wet screen analysis and a certain quantity, usually 0.5 - 1.0 kg, is used at each grinding test. The grinding prod- ucts are also wet screened for their size distribution. 2.1. Ring Mill Batch Tests . The procedure is similar to the previous batch tests the difference been the mill …

Attritors, wet grind Attritors, regular speed Attritors, and high speed Attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm.
Diameter – depending on the material, ranging from 0.05 mm to 2 mm for small media mills, up to 1/8" to 1" for traditional Attritors and up to ½" to 2" for ball mills Composition – metallic grinding media like carbon steel, forged steel, stainless steel or chrome steel grinding …

Sep 01, 2013· A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters.
