Autogenous grinding mechanism is proposed in this paper to have a grinding where the grinding media is itself. In this process, the harder fraction of coal is not grinded and this will enhance the breakage through grain boundaries due to bond strength [22,23].Autogenous mills have other advantages like, output of a unit volume for autogenous mills is lower, and the energy expenditure for ...
