AMIT 135: Lesson 7 Ball Mills Circuits Mining .
Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns. The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges

Energy and temperature analysis in grinding
grinding energy compared with shallow grinding and creep grinding. The chips take away most of the heat generated in the grinding process. As in creep grinding bumout of the coolant causes a steep rise in contact temperature of the workpiece. 1 Introduction
