提高选矿设备备品备件的质量,或改进其结构延长使用寿命,降低备品备件消耗量带来的效果是直接的。例如一台2.7×3.6米磨机一年少耗0.5套衬板,则以几万元计。有的备品备件,例如磨机勺头,节省一个、两个,本身的价值不大,但其效果反映在提高作业率所带来的增产额,却是较大的。 Improve the quality of spare parts of mineral processing equipment, or improve its structure to extend the service life, reducing the consumption of spare parts caused by the effect is direct. For example, a 2.7 × 3.6 m mill consumes less than 0.5 liner a year, then tens of thousands of dollars. Some spare parts, such as mill spoon, save one, two, in itself, the value is not, but the effect is reflected in the increase in operating rates brought about by the yield, but it is larger.
