【Abstract】 In this paper,a now bath of rock pulverizing,namely,pre-damage-bail milling is deaigned,the mechanism of pre-damage of rock is analysed and the pulverizing results in this flow path under different preliminary pressures are studied.It shows from theoretical analysis and experimental study that pre-damage represents an important orientation for energy-saving in rock pulverizing.更多还原
