一、前言近年来,细粒粉碎在许多工业部门显得来越重要。它不仅涉及到加工的物料量问题,而且还关系到物料品种的多少和对磨矿产品的特殊性质来说其要求能否提高的问题。为此进行了下面列举的试验,明确了一些重要的目的和改善细粒粉碎过程的可能性,并且举例说明了机械技术方面的改进。 I. Introduction In recent years, fine-grained grinding has become more and more important in many industrial sectors. It relates not only to the amount of material being processed, but also to the question of whether the requirements for the type of grinding product can be increased with respect to the variety of the material. The tests listed below were carried out for this purpose, identifying some important purposes and the possibility of improving the fine-grain comminution process, and illustrate the improvements in mechanical technology.
