圆锥破碎机是矿山选矿厂的关键设备之一,其高效运转对保障选矿厂连续平稳地运行有着至关重要的影响。目前各种规格的弹簧式圆锥破碎机在国内大量地生产和使用,德兴铜矿泗洲选矿厂有13台φ2.2 m国产弹簧式圆锥破碎机,在使用过程中时常发生主轴锁紧螺母松动,螺纹主轴头从螺纹根部断裂,直接导致破碎壁松动,急剧缩短破碎壁的使用寿命,加速了动锥驱体的磨损,备件消耗大幅度增加,严重影 Cone crusher is one of the key equipments in the ore dressing plant. Its efficient operation has a crucial impact on the continuous and stable operation of the concentrator. At present, a variety of spring cone crusher production and use in large quantities in China, Dexing Copper Mine Sizhou beneficiation plant 13 φ2.2 m domestically produced spring cone crusher, the spindle lock nut often occurs during use Loose, threaded spindle head rupture from the root of the screw, a direct result of the broken wall loose, sharply shorten the service life of the broken wall, accelerating the dynamic cone drive wear and tear, spare parts consumption increased dramatically, severe shadow
