一、序言采煤机滚筒性能的好坏,直接影响采煤机落煤和装煤的效果。一个性能好的滚筒,必定是采煤量大,单位能耗小,装载率高,块煤率多,煤尘含量低,并有足够的机械强度以及截齿消耗量少。西德埃森采矿研究院回采技术研究所地面试验场对采煤机的滚筒作了大量的井上研究试验,并将取得的数据,再 First, the preface Shearer drum performance is good or bad, directly affect the shearer coal and coal loading effect. A good performance drum, must be a large amount of coal, the unit of small energy consumption, high loading rate, lump coal rate, low coal dust content, and have sufficient mechanical strength and picks less consumption. The West Essen Mining Research Institute of Mining Technology Institute ground test site on the Shearer drum made a lot of Inoue research test, and the data obtained, and then
