介绍了新型盘辊式破碎机的结构特点和工作原理,并进行了粒度试验研究。试验结果表明,该破碎机破碎比大,破碎物料细粒级含量高,符合多碎少磨原则。对筛分数据进行统计分析,得到了破碎物料的粒度分布经验公式,可以用来预估破碎机的破碎结果;对影响破碎质量的关键因素进行了分析,提出了一些有利于提高破碎产品质量的措施。 The structure characteristics and working principle of the new disc roller crusher are introduced, and the particle size test is carried out. The test results show that the crusher crushing ratio is large, crushing material with high levels of fine-grained, in line with the principle of more crushing and less grinding. The statistical analysis of the screening data obtained particle size distribution of broken material empirical formula can be used to predict the crusher crushing results; analysis of the key factors affecting the crushing quality, put forward some conducive to improve the quality of broken products Measures.
