Sep 24, 2010· One of the model in which pavement material can fail is by crushing under compressive stress A test is standardized by IS:2386 part-IV and used to determine the crushing strength of aggregat The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.
work index covering grinding of fine particles is labelled M ib (Morrell, 2008) M ia values are provided as a standard output from a SMC Test® (Morrell, 2004a) whilst M ib values can be determined using the data generated by a conventional Bond ball mill work index test (M ib is NOT the Bond ball work index) M ic and M ih values are also.

the SMC Test® can be re-used for Bond ball work index testing, the SMC Test® being effectively used as a feed preparation step for the Bond ball work index test As a general rule Bond ball work index tests are recommended when SMC Tests® are carried out as this provides valuable additional information on the way that much finer particles break.
It was obvious that d80 was decreased with increasing grinding time and decreasing work index, but the effect of grinding time on d80 was more at lower values of work index rather than higher valu Also, the feed size of ore had no effect on the interaction effect of grinding time and work index at.
