Attrition Mill Grinding of Refractories - Union Process

UNION PROCESS INC. • 330.929.3333 • unionprocess 4 of 10 Media sizes for attrition grinding range from 2.0 up to 25.0mm. Smaller grinding media generally result in faster particle size reduction because for a given volume there will be more impact and surface contact. As media become smaller than 2.0mm; mass is significantly reduced

Nov 01, 1999  The interpretation of attrition as a comminution process makes sense because of the newly formed fine particles or size reduction of coarser fractions. For grinding kinetics, we can use known models. Similar to this interpretation is the interpretation of attrition as a process on the surface, similar to the wear of grinding beads during ...
