The Research On Grinding Mechanism And Grinding Effect Of Tube Roll Mill

Tube roll mill belongs a new generation energy saving grinding system developed after roller and rertical mill in the 1990' s. Materials enter from one end of the tube, grinded between tube and roll through leading equipment, The grinding times be changed. The character of tube roll mill is that it combines the advantages of ball mill and roller, then great improves the grinding efficiencyThrough the study of the grinding theory of tube roll mill, pressing stress, grinding effect and the comparation between roller and vertical mill,this text combined the national important technology equipment crert item--tube roll milling developing item, gets following results:Firstly, because of the special structure of tube and roll, powder from single particle grinding in the early peried contincely transit press grinding stage, it better stops the loss of splash energy, secondly, during the grinding progress, powder form loose to dense fully uses the nonsmoth surface of particle and stress focus to make its stress lower than roller' s. lastly, Pressing stress is related with enter angle, structural parameter, the progression and physical character of the poweder. The experiment verified tube roll mill' s grinding effect prior vertical mill and roller. It provides some theory advice for tube roll mill' s industrial apply.
