大冶铁矿有6台φ2100圆锥破碎机,每年均有1～2台机身需要大修。需修复的磨损面主要有上口的φ2700和φ3000内外锥面、φ1500mm球面轴承座的配合面和48个φ48mm的弹簧螺栓孔。 过去,我矿修理机身时,只对上口的两个锥面补焊或焊上一层钢板,这种方法很难使机身恢复原有的配合尺寸,不能使机身与支承套保持紧密的配合,使用寿命较短。较好的修理方法是在磨损面堆焊后,上机床切削加工至要求尽寸。由于机
Daye Iron Mine has 6 φ2100 cone crusher, each year there are 1 to 2 need to overhaul the fuselage. The wear surface to be repaired mainly has φ2700 and φ3000 inner and outer conical surfaces, φ1500mm spherical bearing surface and 48 φ48mm spring bolt holes. In the past, when I repaired the fuselage mine, only the upper two cone welding or welding a layer of steel, this method is difficult to make the fuselage to restore the original with the size, can not make the fuselage and support sleeve to maintain Close cooperation, short service life. A good method of repair is surfacing on the wear surface, the machine tool cutting to the required size. Thanks machine
