A disintegrating or pulverising machine having beaters revolving in a casing, a stationary impact block within said casing having its impact surface arranged at such an angle relative to the position of the feeding orifice or orifices in the casing and the axis of the rotary beaters that the material is thrown by the beaters against the said block in a direction substantially normal to its surface, in order to limit the zone of pulverisation and wear on the casing to the vicinity of the block, and to keep the material in this zone until disintegrated small enough to be carried under the block by the air-current set up by the rotary beaters, substantially as described. (2.) A disintegrating or pulverising machine having beaters revolving in a casing, in which the material is thrown by the beaters upon a screen so that the graded material is separated from the larger particles, which return to the beaters for further disintegration, the dust being carried off from the front and back of the screen by the air-current set up by the beaters in the casing so as to leave the graded material free from dust, substantially as described. (3.) In a rotary disintegrating or pulverising machine having beaters or lifters, the mounting of the beater or lifter heads upon stems of a flexible character capable of axial compression, but of sufficient rigidity in an axial direction to support the beater-heads in their normal radial position, substantially as described. (4.) In a disintegrating or pulverising machine having beaters or lifters, the mounting of the beater or lifter heads upon stems consisting of wire rope, and clamping-means for the attachment of the strands thereof to the respective parts, substantially as described. (5.) In a disintegrating or pulverising machine having beaters or lifters, wire-rope stems for carrying the beater or lifter heads, and a protecting sleeve to each stem arranged so as not to interfere with the flexibility or compressibility of the stem, substantially as described. (6.) The arrangement and construction of a disintegrating or pulverising machine substantially as described, and illustrated by the drawings.
