    摘要： A mill with capability for rapid replacement of wearable moving components and capacity for precision grinding movement. The wearable moving components form a package of dual counter-rotating rotor centrifugal devices, the package including first and second motors (2, 5), counter-rotating first and second rotors (1, 4) driven by the first and second motors, respectively, a hollow shaft (6) connecting the first motor to the first rotor, and a solid shaft (3) connecting the second motor to the second rotor, the solid shaft running inside the hollow shaft.

    摘要： The essence of the invention is that it involves the feed of a material to be ground and the acceleration of said material. During acceleration, jets are formed from a mixture of material to be ground and air and said mixture is fed to an annular grinding chamber. Simultaneously, a stream of air is fed into the grinding chamber in a direction contrary to that of the mixture jets. Local cyclic variations in the pressure and rate of the air stream and/or in the pressure and rate of the mixture jets are formed along the perimeter of the grinding chamber. The finished product is removed. The material grinding device comprises a housing with a unit for the feed of the material to be ground and a unit for the removal of the finished product. An annular grinding chamber is accommodated in the housing. Two rotating rotors with the blades fastened thereto are coaxially arranged in the housing. The blades for accelerating the material to be ground and feeding said material into the grinding Chamber and/or the blades for feeding air into the grinding chamber are arranged at varying intervals.

    摘要： This invention relates to means for pulverizing coal or other minerals by causing them to impact against rotating elements (15,17) which are specially contoured to maximize two objectives: 1) improved efficiency in pulverization of the material particles at high production rates; and 2) protection of the rotating elements themselves from wear by contact with the process material.
    The device is formed with counter-rotating rotors (26,28) which are inverted with respect to each other. The rotors (26,28) have specially contoured elements (15,17) attached to their inner faces in concentric rings. The elements could be any one of four different embodiments or a combination of two or more different elements forming successive rings.
