2 — GEAR DISTRESS AND FAILURE MODES Distress or failure of gears may be classified into four categories: 1 – surface fatigue (pitting), 2 – wear, 3 – plastic flow 4 – breakage. The appearance of the various distress and failure modes can differ between gears that have through hardened teeth and those that have surface hardened teeth.
Few things can ruin a machinist''s day more easily than a broken, chipped, or prematurely worn down end mill. Besides requiring replacement, a compromised cutting tool can produce subpar results and scrapped parts. Stop killing your end mills and extend your tool .
The wear failure is the most important form of liner failure. Usually due to normal wear and failure, it consumes the largest metal materials. Ball mill liner wear process is very complex, affected systems to various factors, the wear characteristics of the grinding mechanism and the entire change in the parameters of the system leads to wear ...

May 23, 2012· Wet ball mill is the material being broken to smash the key feeding, discharging part, turning part, a transmission of the main widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and nonferrous metal processing and glass ceramic production industry, for all kinds of ores and other materials may be grinding of dry .
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

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.
