ROTOR FOR IMPACT TYPE CRUSHER

摘要

PROBLEM TO BE SOLVED: To provide the rotor of an impact type crusher facilitating the attachment and detachment of a hitting plate without the need of a special device or space and simplifying the attaching structure of the impact plate. SOLUTION: A plurality of attaching grooves are arrayed in the longitudinal direction of a shaft at equal intervals on the outer periphery of a plurality of rotor plates fixed to the shaft, holders provided with two projecting lines in the longitudinal direction of the shaft on a surface are oppositely mounted on both sides of the attaching grooves of respective columns and the hitting plate provided with two projecting lines on both side faces is held between the holders of the respective columns by engaging one of the projecting line between the two projecting lines of the holders. The respective projecting lines of the hitting plate are provided with one or more notched part and the notched part is positioned between the projecting lines of the length equivalent to or appropriately shorter than the notched part. The holder on at least one side of the respective columns is movable in the longitudinal direction of the shaft and the projecting line of the movable holder is provided with the notched part corresponding to the projecting line of the hitting plate.
