1999-11-1  X c is a characteristic size (size modulus) and γ c is a constant which defines the relative width of the distribution (distribution modulus). In accordance with the definitions of fracture and attrition, values of X c are fairly close to the size y of the particle being broken for fracture, and very much less than y for attrition. Some examples of these distributions are given in Fig. 2.

2008-4-1  The size reduction of silica was intensive as the jet mill is energy intensive. Abrasive and destructive breakage mechanisms took place varying according to the operating conditions of the jet mill. The minimum particle size obtained was 3.15 μm with a span value of 1.30. The circularity value of the ground silica ranged from 1.29 to 2.02.
