Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...
The chamber is vibrated at a frequency of between 1000 and 1500 times per minute (can be variable speed) by cams or unbalanced weights. The grinding action is efficient and thorough. Grinding media material and chamber lining can vary depending on application. Vibrating mills are usually batch mills and can grind hard or soft materials.

Long service life of wearing parts: the grinding roller and grinding ring are forged with special materials, which greatly improves the utilization. In the case of the same fineness of materials and finished products, the service life is 2-5 times longer than the wear parts of impact crushers and turbo crushers, generally up to more than one year.
Dressing. When the sharpness of grinding wheel becomes dull because of glazing and loading, dulled grains and chips are removed (crushed or fallen) with a proper dressing tool to make sharp cutting edges and simultaneously, make recesses for chips by properly extruding to grain cutting edges. Thus, these operations are for the dressing. Trueing.
