THE EFFECTS OF BALL SIZE ON THE DETERMINATION OF

高达10%返现  Apr 01, 2021  Austin, Klimpel, and Luckie (1984, 93–94), stated the effect of ball diameter on rate of breakage as “considering a representative unit volume of mill, the rate of ball-on-ball contacts per unit time will increase as ball diameter decreases because the number of balls in the mill increases as \(1/d^{3}\). Thus the rates of breakage of ...

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
