一、磨矿工段的操作目前,磨矿是與分级成闭路进行的,这时磨好的部分矿石,多半用分级机分离出来,在某些情况下,也使用筛分机,没有磨好的矿石,即叫做循环负荷(分级机的返砂和筛分机的筛上产品)返回到磨矿机中进行再磨矿。正确地选择循环负荷量,可以避免过磨碎,从而在下一步选矿时(浮选和摇床精选等等)有可能提高精矿质量,以及提高精矿中某种金属的採收率。
First, the operation of the grinding section At present, grinding and classification into closed-circuit, then grinding part of the ore, mostly separated by a grader, in some cases, the use of screening machines, there is no grinding of ore , Which is called a cyclic load (grader sand return and screening of screen product) is returned to the mill for refinishing. Correctly selecting the cyclic loading avoids over-grinding, which may improve the quality of the concentrate and increase the recovery of some metal in the concentrate during the next beneficiation (flotation and shaker selection, etc.).
