PFY硬巖反擊式破碎機 Impact crusher for hard rock

國家行業(yè)標準JB/T10246

PFY系列反破碎機是我廠在吸收國內外先進技術，結合國內砂石行業(yè)具體工礦條件而制的最新一代反擊破碎機，該設備具有破碎比大、礦碎后物料呈立方體顆粒、耐磨件使用壽命長等優(yōu)點，推廣使用后為用戶取得了明顯的經濟效益。

PFY impact crushers for hard rock are the newest generation of  impact crushers developed by our factory by absorbing advanced technology at  home and abroad and according to actual working conditions in domestic sand  industry. Such equipment enjoy advantages such as big crushing ratio, the shape  of cubic particles of materials after crushing, and long service life of  wear-resistant parts. Users of it gain considerable economic benefits.

物料進入機體后碰上高速旋轉的錘頭迎關打擊，大塊物料立即被打碎，碎料高速飛向支擊板，進行第二次碰撞破碎，反彈物料與后續(xù)來的物料相互撞擊破碎達到最終破碎目的。

After the materials enter the machine, they bump against the  rapidly rotating hammer. As a result, bulk materials are broken into pieces  immediately. Then the broken materials fly to the striking plate for the second  collision and crushing. The rebounded materials collide with the later-coming  materials to realize utter crushing.
