摘　　要：回转式破碎机的破碎功能是通过偏心回转辊和固定凹面破碎板组成的破碎腔来实现的。破碎腔啮角呈静态和动态变化，且从大到小，使该机具有高频破碎、高密破碎、渐进破碎和强制排矿功能，从而破碎能量集中，效率高，能耗低，磨损小。破碎鹅卵石的工业试验结果表明，该机的生产能力比颚式破碎机提高近１倍，能耗约降低４０％，钢耗降低５０％以上，破碎产品的粒度分布更趋合理。Crushing functions of a rotary crusher are achieved by its crushing cavity con-sisting of an eccentric rotary roller arid a fixed notch crushing plate. Dynamic and static Vari-ations in its cavity' s nip angle can make it to have a number of functions,such as high fre-quency crushing,high density crushing,progressive crushing and forced discharge,resultingin concentratioii of crushing energy, high crushing efficiency,low energy consumption andless wear. The results obtained by industrial tests of crushing cobble stone show that com-pared with a jaw crusher the crusher's capacity is increased by a factor of abOut 2,energyconsumption decreased by 40%,steel consumption decreased by above 50% and more ratic-nal size distribution can be achieved.
