FIELD: agricultural engineering. ^ SUBSTANCE: invention is designed for grinding and mixing of components when preparing formulated feed. Proposed grinder-mixer has housing with charging and discharge branch pipes, rotor in form of disk with working member, sieve shell, tenons installed on inner side surface of housing. Tetrahedral wedges of working members are made in form of regular tetrahedral pyramids. Teeth in form of regular hexagonal star pyramids are made on two opposite side surfaces of faces of tetrahedral pyramids. On two other opposite side surfaces of faces of tetrahedral wedges, pyramidal channels are made in form of truncated hexagonal pyramids, teeth and channels being arranged relative to each other in cellular order. Conical slot is made in one of tetrahedral wedges, and four-blade impeller with triangular shape of blades is fitted on lower part of rotor. ^ EFFECT: possibility of grinding and mixing several components simultaneously. ^ 2 cl, 4 dwg
