当前,黄金矿山磨浮流程粗磨作业普遍采用格子型球磨机与螺旋分级机闭路配置使用。其优点是螺旋分级机构造简单,工作可靠,操作方便,在闭路磨矿中能与磨机自流连接。但它也有自身的缺点,即分级效率低,设备笨重,消耗备件费用高,占地面积大,因此在当今选厂设计中逐渐被水力旋流器所取代。水力旋流器的主要特点是结构简单,本身无 At present, the coarse grinding operation of the gold mines in the frothing and floating process is generally adopted by the lattice type ball mill and the spiral classifier closed-circuit configuration. The advantages of spiral grader structure is simple, reliable, easy to operate, in closed-circuit grinding mill with gravity connection. But it also has its own shortcomings, namely, the low efficiency of classification, bulky equipment, high cost of spare parts and large area, so it is gradually replaced by hydrocyclone in today’s plant design. The main feature of hydrocyclones is their simple structure, without themselves
