Aug 21 2003 [0080] A preferred method for testing the existence of residual internal stress of a composite mill blank is the Thermal Shock Test involving the use of liquid Nitrogen Residual internal stress is undesirable because it adversely affects the structural integrity of the blank and increases the likelihood of later catastrophic failure of the

However for a few nonparametric {K} tests this is not the case Examples are ASTM Test Method for Scaling Resistance of Concrete Surfaces Exposed to Deicing Chemicals (C 672) that uses an ordinal scale of measurement and ASTM Test Method for Organic Impurities in Fine Aggregates for Concrete (C 40) that uses a nominal or classification scale

Aug 01 2013 As an example by use of high speed photography Kumar et al (1989) have observed that at 70 rpm in a 2D mill setup used to wet grind quartz all the balls in the mill interact with each other and with the ore through mutual sliding rolling and colliding At 86 rpm approximately 50 of the balls went out of circulation reducing the probable number of interactions in one revolution of the mill

Aug 01 2013 A wide range of materials is used to resist wear in comminution processes (Durman 1988 Moema et al 2009) The abrasiveness of the material being processed is of prime importance in determining the absolute wear rate of the grinding media but conflicting characteristics of high hardness for maximum wear resistance and adequate ductility to avoid catastrophic brittle failure in application
