目前,国内外自磨试验一般分为两步:第一步为介质适应性试验;第二步是半工业试验。介质适应性试验的目的是评价在待磨矿下物料中可以充当磨矿介质的矿石数量有多少。如果在给矿中没有足够的具有介质粒度的矿石,或者具有介质粒度的矿石,但在自磨机中不起介质的作用,这种情况下,自磨是不可能的。 At present, the self-grinding test at home and abroad is generally divided into two steps: the first step is the medium suitability test; the second step is the semi-industrial test. The purpose of the media suitability test is to evaluate how much of the ore can be used as grinding media in the material to be milled. If there is not enough ore with medium size in the ore or an ore with medium size, it does not function as a medium in the self-grinding machine. In this case, self-abrasion is impossible.
