DRY GRINDING ATTRITORS
The Dry Grinding Process. The Attritor dry grinding process is achieved in a stationary tank by means of a rotating shaft and arms that agitate the media into a random state of motion of internal porosity called kinematic porosity. In this expanded condition, the media and particles are free to move, collide and impinge upon each other.

Grinding Parameters | SpringerLink
The basic process parameters in grinding processes are the cutting speed v c, the feed velocity v f, the depth of cut a e, and the width of cut a p (see Fig. 1, see also Denkena and Tönshoff 2011 ). The cutting speed is in general equal to the circumferential speed of the grinding wheel. The feed velocity is oriented in feed direction.

UNIT 2 GRINDING Grinding
Some straight wheels are shown in Figure 2.1 Types 1, 2 and 3. These are generally used for cylindrical, internal, centreless and surface grinding operations. These wheels vary in size, diameter and width of the face. All the parameters depend on the clays of work for which the wheel is used, size and power of grinding machine using the wheel.
