该机为原料的粉碎碾练设备。辊圈材料采用耐磨球铁和
合金钢，并经淬火处理。硬度分别可达HRC60°、62°，HRC48°，55°；辊圈子上没有布料器，不但整个辊圈宽度上均可发挥破碎作用，提高破碎细度和产量，也可使辊圈均匀磨损，有效解决辊圈中间拉槽现象。
This machine is mainly used for crushing and pulerizing .The arc is made of wear-resist cast iron and alloy steel.and has been quenched to HRc60-62,HRC48-55.A cloth machine on the arc can not only crush but also prevent dragging the trough.
