### ATTRITORS AND BALL MILLS HOW THEY WORK Robert E.

balls (media) in their random movement are spinning in different rotation and, therefore, exerting shearing forces on the adjacent slurry. As a result, both liquid shearing force and media impact force are present. Such combined 2. shearing and impact results in size reduction as well as good dispersion. The principle of Attritor dry grind processing is achieved by an expanded moving bed of

### Ball and Roller Bearings - NTN SNR

Rolling elements classify in two types: balls and rollers. Rollers come in four types: cylindrical, needle, tapered, and spherical. Balls geometrically contact with the raceway surfaces of the inner and outer rings at "points", while the contact surface of rollers is a "line" contact. Theoretically, rolling bearings are so constructed as to allow the rolling elements to rotate orbitally while
