铜录山矿选厂使用φ2700×3600球磨机的总重(包括钢球)120吨,只配备一台30/5吨吊车,满足不了大修的要求。以往检修轴瓦和更换大齿圈时,采用四台100吨的油压顶顶起,劳动强度大,工作效率低,顶起球磨机费时3天。经过三结合小组的研究,选用我矿库存备件,自行设计和制造了二台电动双螺旋顶。二年来使用效果很好,仅用4个小时便完成球磨机的升降,工作效率大大提高。
Tongluoshan ore processing plant using φ2700 × 3600 ball mill total weight (including ball) 120 tons, only equipped with a 30/5 ton crane, can not meet the overhaul requirements. In the past, when repairing the bearing bush and replacing the ring gear, four 100-ton hydraulic jacking jacks were used. Due to the labor intensity and low working efficiency, the jacking up of the ball mill took 3 days. After three combined groups of studies, the selection of mine spare parts inventory, to design and manufacture of two electric double helix roof. Two years to use a good effect, only 4 hours to complete the ball mill movements, work efficiency greatly improved.
