In wet grinding, the surrounding medium is liquid, as opposed to dry grinding. Wet grinding should be considered in cases where the material is prone to static charging, or when the material is toxic and dust containment is difficult. Also wet grinding can be used when the final product size is
The abrasives may be used also in powder form by charging the grinding surfaces with the abrasive in a premixed slurry or suspension. SiC particles, particularly with the finer size papers, embed easily when grinding soft metals, such as Pb, Sn, Cd and Bi see Figure 3.1.
Jul 01, 2003 Figure 3 depicts the effects of media size on grinding times. From this plot, it is shown that a target fineness of 80 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes.

The material charge is equally important in running an efficient milling operation. If too little material is loaded with the media, it will mostly stay in the voids between the media and the media will just grind against each other. Too little material will cause excessive wear on the media while grinding very inefficiently.

When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils thousandths of an inch.In the metric system, the micronone millionth of a meter is used.
