目前，普遍认为“多碎少磨”是降低碎磨作业能量消耗的有效途径之一，实践也证明了这一设想。本文拟从定量的角度探讨一下“多碎少磨”的节能效果。为定量探讨‘哆碎少磨”的节能效果，现作如下假定。当然，这些假定条件应该是与实际碎磨作业条件相一致。1．总的碎磨比不变对于 At present, it is generally accepted that “more crushing and less grinding” is an effective way to reduce the energy consumption of crushing operation, which is proved by practice. This article intends to explore from a quantitative point of view, “more broken and less grinding,” the energy-saving effect. In order to quantitatively discuss the energy saving effect of ’Dao Shao Shaowu’, the following assumptions are made, of course, these assumptions should be consistent with the actual crushing operation conditions.1 The total crushing ratio unchanged For
