Cutting mills are suitable for the grinding of soft, medium-hard, elastic, fibrous, and heterogeneous mixes of products. The new cutting mill SM 200 is a powerful and easy-to-operate instrument for efficient primary and fine size reduction. Cleaning is made particularly easy.
The fine grinding characteristics of hard materials such as synthetic diamond and alumina were investigated by means of an attrition mill. The grinding kinetics approach was successfully applied to the analysis of product size distributions obtained under various process conditions.
The tests demonstrated attrition milling with an Ottawa sand medium to be a promising method of producing a high-surface-area silica catalyst. In both hexane cracking and ethanol dehydration, new silica surfaces created by attrition milling were more catalytically active than two commercially available amorphous silica catalysts.
