Abstract (en)
A crushing member of a gyratory crusher for crushing materials successively from an upstream side towards a downstream side of a material flow direction. The crushing member comprises a mantle (1) having a frustoconical outer structure and composed of a teeth plate member (2) formed of a material having high anti-wearing property and a plurality of grooves (3,6,7) formed to an outer peripheral surface of the teeth plate member (2). The grooves (3,6,7) are arranged in a plurality of circumferential stages of the outer peripheral surface of the teeth plate member (2) so as to extend parallelly along a generating line of the mantle (1) and disposed with spaces from each other in the respective stages. Each of the grooves (3,6,7) formed to a peripheral surface portion on the downstream side of the material flow direction has a pitch and a width narrower stepwise than those of the grooves (3,6,7) formed to a peripheral surface portion of the upstream side of the material flow direction. The grooves of the downstream side are substituted with a plurality of groove forming members casted into the downstream side portion of the members disposed with spaces from each other. The groove forming members each has a pitch and a width relatively narrower than those of the grooves and is formed of a material having a low anti-wearing property. <IMAGE>
