Attrition Grinding Mill Design

The studies, which used Ottawa sand as the grinding medium, provided data on such ceramic powders as barium ferrite, calcite, dolomite, fluorspar, silica, and zirconia. These tests for the most part verified earlier data in demonstrating that the attrition milling process was much more efficient than other fine-grinding processes.

Machining of ceramics [SubsTech]

Ultrasonic machining (UM) of ceramics is the machining method using the action of a slurry containing abrasive particles flowing between the workpiece and a tool vibrating at an ultrasonic frequency. The vibration frequency is 19 ~ 25 kHz. The amplitude of vibration 0.0005 - 0.002" (13 – 50 μm). During the operation the tool is pressed to the workpiece at a constant load.
