Tube mill. Tube mills consist of revolving cylinders, with a number of hard balls which act as the grinding media. Tube mills differ from ball mills essentially in having an inlet for material feed and an outlet for the ground material. Hence, tube mills have larger length to diameter ratio 31 as compared to ball mills

Attrition Mills Powder Metallurgy Beyond Discovery

Attrition Mills Powder Metallurgy Beyond Discovery

Jul 09, 2021 Milling in an attrition mill Fig. 24 is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills..

Cast Iron Metallurgy for Dummies

Cast Iron Metallurgy For Dummies

Cast iron is derived from pig iron, and while it usually refers to gray iron, it also identifies a large group of ferrous alloys which solidify with a eutectic. The colour of a fractured surface can be used to identify an alloy. White cast iron is named after its white surface when fractured, due to its carbide impurities which allow cracks to pass straight through.
