Measurement and statistics of single pellet mechanical

Mechanical-strength measurement methods for differently shaped solid catalysts such as crushing knife-edge cutting and three-point bending have been discussed The strength data were correlated by Weibull distribution Experimental results show that except for the crushing strength test on extruded catalysts all strength tests have a single fracture mode and the strength failures are due

Automated Crush Strength of Spherical Catalysts

This method is for determining the crush strength of spherical catalysts using a Chatillon motorized sample stand and force gauge or tablet hardness tester The method applies only to spherical particles having a nominal diameter of 1 6-mm (1/16-inch) or larger The measurement range is from 250 Newtons (N) (56 lbf) down to 1 N (0 22 lbf) Test apparatus other than the Chatillon may be used

A Model for the Bulk Crushing Strength of Spherical

Statistics and experiments reveal that the mechanical failure of a spherical catalyst under single-particle crushing strength and bulk crushing strength tests are both brittle fracture and the fact that the single particle strength data follow a Weibull distribution A model is proposed for the packing of spherical particles which assumes tetrahedral contact and force transmission between the
