Working tool with driving and driven disks is mounted within casing. Cover is fixed on casing for rotation on pin. Driven disk is positioned for reciprocating relative to casing and spring-loaded relative to latter. Working inserts with grinding members are mounted on disks, with height of grinding members decreasing in the direction of disks peripheral parts. Conical entry portions are positioned on disk surfaces faced one to another. Scattering spades are mounted on driving disk and driven disk is provided with projections for effectuating primary grinding operation and feeding channels. Grinding members on inserts of one disk are arranged at an angle to grinding members on inserts of other disk. Such construction allows optimum grinding conditions to be provided and material grinding extent to be adjusted. EFFECT: increased efficiency, convenient repair and maintenance, improved homogeneity of ground product. 4 cl, 6 dwg
