A drop weight tester was designed for the purpose of analyzing single particle impact breakage characteristics of different materials. Test results were evaluated through the breakage distributions of different size fractions at various impact energy levels. Breakage parameter t10 (Narayanan, 1986) is used to represent the degree of size reduction which is assumed to be represantative of the breakage product size distribution obtained from drop-weight tests. Relation between specific comminution energy level and breakage index number (t10) was established on the size fractional base so that the variation in impact breakage characteristics of different materials can be evaluated. It can be concluded that, drop-weight test method is a useful and practical way of evaluating the impact strengths of various materials on the size fractional base and results of which can be used in the mathematical modelling of autogenous and ball milling.
