  2. The character of tube roll mill is that it combines the advantages of ball mill and roller, then great improves the grinding efficiency through 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

    本文結合國家重大技術裝備國產化創新項目-筒式輥碾磨開發項目，通過對筒輥磨的粉磨機理、層壓應力的分析、粉磨效果的研究及與輥壓機、立磨粉磨效果、粉磨機理的比較，可知：首先，由於筒與輥的特殊結構方式，筒輥磨內粉體由初期的單顆粒破碎逐漸過渡到層壓粉碎階段，較好地防止了飛濺能的損失，其次，在粉磨過層中，粉體由疏鬆到密實，充分利用了顆粒的非光滑表面及應力集中效應使其應力低於輥壓機。實驗證實，筒輥磨的粉磨效果大大優于立磨和輥壓機。
