前言碎样在岩矿鉴定和地质分析工作中占有重要地位。当前,大多数是采用机械破碎和人工手碎等方法。但是这些方法往往损耗大,矿物受热变质,劳动强度大,效率低。为了改善这种状况,受中国地质科学院的委托,在沈阳地质矿产研究所研究的磁力锤基础上,对原有控制线路和机械结构进行了改进,重新设计并试制成功了 Preface The broken sample occupies an important position in rock and mine identification and geological analysis work. At present, most of them adopt methods such as mechanical crushing and manual hand crushing. However, these methods are often lossy, mineral heat deterioration, labor intensity, low efficiency. In order to improve this situation, commissioned by the Chinese Academy of Geological Sciences on the basis of the magnetic hammer researched by Shenyang Institute of Geology and Mineral Resources, the original control circuit and mechanical structure were improved, redesigned and trial-produced successfully
