Zusammenfassung:Provided is a pulverizing, stirring, mixing, and kneading machine member which is lightweight, has excellent impact resistance and wear resistance, and is magnetic, and which has a long service life. Namely, the present invention provides a comminuted, stirred, mixed and kneaded machine component comprising cermet, in which raw materials are blended in such a manner that the mass ratio of Ti: 20-45%, Mo: 5-35%, W: 6-30%, C: 5-15%, Co: 10-50%, and the total of Co and Ni is more than 25% but not more than 50% for each element, the raw materials are mixed to obtain a mixed powder, the mixed powder is press-molded to obtain a pressed body, and the pressed body is sintered to obtain a sintered body. A cermet is obtained by sintering the pressed body. The cermet has a core phase (2) mainly composed of TiCN, a ring phase (3) mainly composed of (Ti, Mo, W) (C, N) and a metal phase (4), the average particle diameter of a hard phase composed of the core phase and the ring phase in cross-sectional structure observation
