A crushing member of gyrating-type crushers (10), including a mantle (12) and a concave (18), the crushing member comprises a plurality of groove forming members (16, 22) in the shape of a strip circumferentially spaced from each other by a set pitch on crushing surfaces of the mantle (12) and the concave (18), the groove forming members (16) of the mantle (12) defining a direction line (17) forming a direction angle of 45 DEG - 75 DEG with respect to a vertical direction line (Z1, Z1) of the mantle (12), and the groove forming members (22) defining a direction line (23) normal to a vertical direction line (Z2, Z2) of the concave (18). Thus direction lines of the groove forming members embedded in the crushing surfaces of the crushing toothed plate member bodies, and their combinations can optimize the crushing achievement. <IMAGE> |
