The essence of the invention is that the material grinding device comprises a housing with a unit for feeding the material to be ground and a unit for removing the finished product. An annular grinding chamber and two rotors are accommodated in the housing. The rotors are coaxially arranged and can rotate. Blades for accelerating the material to be ground and feeding sad material into the grinding chamber are mounted on one of the rotors. Blades for supplying air into the grinding chamber are mounted on the other rotor. The device is provided with at least one distributor. Said distributor is designed in the form of blades which are secured on the housing and disposed in the grinding chamber. The vanes of the distributor are equally spaced along a circle, the center of which is situated on the longitudinal axis of symmetry of the rotors.
