近年来,沈阳电力机械厂引进国外先进技术生产的环式碎煤机已经在不少燃煤电厂得到应用,对大块煤的破碎效果良好。大块煤在环式碎煤机中受四排交错安装在转子上的锤环的剪切、挤压、滚碾、研磨,破碎后的煤经格栅落入下层落煤管。同时,带齿锤环将不易破碎的铁块、木棒等杂物拨入碎煤机前设置的除铁室内,每次停止运行后,打开除铁室门,可及时把杂物清理干净。近两年来,开封火电厂对本厂的两台 In recent years, Shenyang Electric Power Machinery Factory to introduce advanced foreign technology ring crusher has been applied in many coal-fired power plants, the crushing effect of large coal good. Large lump coal in the ring crusher by four rows alternately staggered mounted on the rotor hammer ring shear, extrusion, rolling, grinding, crushed coal falls into the lower coal through the grid. At the same time, with a toothed hammer ring will not be easy to break the iron, sticks and other debris dial into the crusher before the set of iron room, each stop running, open the iron room door, the debris can be cleaned up in a timely manner. In the past two years, Kaifeng Thermal Power Plant of the factory two
