I assume you are referring to a ball mill, since cyclone discharge recycle normally goes back to ball mill feed. I am less versed in ball mill grinding. Ball mills break rock by compression fracture, while SAG mills predominantly break by shear. Some compression fracture does occur, but, it is not the major comminution mechanism.

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.
Seizing is one of the most common failure modes when bearings are first put into service. The lack of rolling element rotation results in a rapid and excessive rise in temperature. The surface hardness of the bearing races and rollers or balls is reduced, and the bearing is quickly rendered unsuitable for use. This is illustrated in Figure 11.
Flaking and pitting modes do not develop normally during grinding of ore in a ball mill because abrasive wear proceeds at a faster rate. Steel balls abrasion The abrasive wear of the steel balls determined from the pinon drum wear test ranged from to mm³/m.
CNC ballscrew inspection, warning signs for failure and ballscrew problems to look for to help determine the need for replacement. Ballscrew backlash, contamination and ball nut loss of preload are just some of the problems you will find causing problems when your machining. Learn how to analyze what is causing ballscrew failure.
Things break. No matter what you do, there is always a chance that products will fail. The same holds true for bearings, but that doesn''t mean that you can''t prevent many of the issues that result in costly downtime.. This article is a guide to the major factors that can lead to bearing failure as well as how you can prevent the issues from happening.
Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications.
