摘要
在对四凸瓣磨盘圆盘粉碎机制备矿样过程中的运动、受力和粉碎机理分析的基础上,针对其定磨盘凸瓣间的物料因缺少几何约束,导致加工料腔压力减小,物料回流等影响,提出了改进设计方案。通过对改进后的动磨盘在对物料粉碎进行粉碎过程的分析研究,得出:动磨盘增加抛料槽结构后,克服了卧式圆盘粉碎机动磨盘的旋转,无法实现带动所有进入磨盘中的物料随之转动的缺陷;实现了在磨盘加工料腔内沿圆周法线方向的层压粉碎;使被加工物料可以被粉碎的更细。为圆盘粉碎机的优化提供了一种选择。
Based on the analysis of motion, force and the crushing mechanism in the ore sample preparation process of four convex disc .gyradisc crusher, this paper puts forward the improved design scheme aimed at processing materials cavity pressure decrease and material backflow caused by lack of geometric constraint for material between two convex disc. In research of pulverization process with improved moving millstone, conclusions made are as follows： compared to horizontal disc grinder moving disc which is unable to drive all the material into the disc in rotation, moving millstone plus throw trough structure implements laminated crush in millstone processing materials cavity in direction of circumference of the normal and produces finer processed material.
