ii Mechanism of Crushing of Rocks under Dynamic Loading Sheng Huang Doctor of Philosophy Department of Civil Engineering University of Toronto 2016 Abstract In the mining and quarrying operation, rock crushing process consumes a large amount of energy.
Mathematical models of crushing processes are based, as a rule, on mass preservation laws and their parameters determination needs some assumptions. The basic assumption is an independence of crushing various components of feed. The theory of finite mixture distributions of random variables (the method of moments and the method of maximum likelihood) was used in the work in order to check …
