银山铅锌矿选矿厂是60年代初建成的。目前,该厂生产能力为1600t/d左右,有8台球磨机,其中5台是φ1.5m×2.95m的湿式格子型球磨机。这类球磨机是30年代的产品,其传动结构为二级减速传动,第一级为皮带传动,第二级为大小直齿轮传动。该传动存在的主要问题是传动不平稳,不准确,3个滑动轴承座易产生受力不均使轴瓦烧坏或使传动小齿轮轴易扭弯断裂。为此,1990年,笔者对5号球磨机进行设计改进,将第一级的皮带传动
Yinshan lead-zinc ore dressing plant was built in the early 60s. At present, the plant production capacity of 1600t / d or so, there are eight ball mill, of which five are φ1.5m × 2.95m wet lattice ball mill. This type of ball mill is a product of the 30’s, the transmission structure for the two deceleration drive, the first stage for the belt drive, the second level for the size of the spur gear transmission. The main problem of the transmission is the transmission is not smooth, inaccurate, easy to produce three sliding bearing blocks are uneven bearing pads so that the shaft or gear shaft easy to twist fracture. To this end, in 1990, the author of the 5th ball mill design improvements, the first level of the belt drive
