Selection and Design of Mill Liners. In Advances in Comminution, Ed. S.K. Kawatra. ISBN-13: 978- ... High–low double wave ball mill liners – These are a refinement of the wave liner, Figure 5. This was applied to Cadia Hill Gold Mine through evaluation of their existing wear profile and wear rate, and provided a more consistent wear profile ...
mesh (1.7 mm) ensuring that the ball mill will work efficiently. Coarser screens than 10 mm will cause serious losses in ball mill efficiency. Ball mill feed must never exceed 80% passing 3 mm if reasonable ball mill efficiency is expected. The practice of using ½ inch screens (trommels) is an encroachment on this limit and is perhaps the most
gear transmission. The gearless ball mill has emerged. Because of its massive volume, the gearless ball mill is difficultto manufacture and maintain. Therefore, a novel module com-bined permanent magnet motor with wrapped type for mine ball mill (MBMWT‐MCPMM) is proposed, eliminating the gear and reduction box in the traditional drive mode and

Therefore, this work proposes a module combined permanent magnet motor with wrapped type for mine ball mill (MBMWT-MCPMM). Based on the principle of removing coils, the stator is modularized. Each module can be regarded as a small rotary motor, which improves the reliability and fault tolerance of the motor. ... In this work, the …
Referring to Table VI the L/D can be between 1.75 and 2.0 or even greater. Referring to Table VII a 3.05 meter (10 foot) by 3.05 meter (10 foot) overflow ball mill with a 40 percent by mill volume ball charge, new liners and 50 mm (2″) balls draws 491 HP. Using equation 5 there will be a loss of 0.55 Kw (0.74 Hp) per metric tonnes of balls.
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill.
