FIELD: mechanical engineering. SUBSTANCE: loose material concentrator has operating member in the form of rotation bowl coupled to drive by flexible element. Concentrator is provided with bowl inclination angle limiter with hole over the edge of which bowl rolls with part of its surface in rotation. Bowl inclination angle may be changed constantly during bowl rotation by selection of surface configuration. Inclination angle limiter is made in the form of curvilinear surface encircling the bowl over which bowl rolls during rotation Curvilinear surface of bowl inclination angle limiter and part of bowl external surface contacting it are made of friction material. At least one of contacting surface is made to curve different from circle. Bowl contact surface is made according to circumference positioned with eccentricity relative to bowl axis of rotation. Contact surface of bowl inclination angle limiter is made according to circumference arranged with eccentricity relative to drive mechanism output shaft axis. EFFECT: more efficient construction. 9 cl, 6 dwg
