Abstract: Generally, described herein are milling devices. A milling device (100) includes a rotatable screw (110) in an outer periphery of which spiral grooves (110a, 110b) are formed; a barrel (120) surrounding the portion of the screw (110) where the spiral grooves (110a, 110b) are formed and in an inner periphery of which a spiral groove (120a) is formed; a loader (130) for loading cereal grains into a space (135) between the screw (110) and barrel (120); a compressor (140) attached to a distal end of the barrel (120) and accumulating and pressurizing in a nearly airtight state the cereal grains ground in the space (135) and fed therein as the screw (110) rotates; and a discharge port (150) provided in a front face of the compressor (140) and blasting the cereal grains fed in and pressurized by way of rotation of the screw (110).
Abstract: The invention relates to the grinding method with simultaneous homogenization of powder-like materials with liquid components in construction engineering, chemical and other industries. The roller breaker-homogenizer comprises a cone-shaped backing roll and not less than three driven rolls and driven rolls, the large bases of which face reverse directions. The rolls are arranged in the case with a replaceable cup vertically at the same level so that the driven rolls are located epicyclically relative to the backing roll and mounted in cantilever fashion in the case cover rotation bearing assemblies, and the backing roll is connected axially with a drive shaft via a spring coupling. An appliance used to regulate the spring coupling pressing force is mounted between the drive and spring coupling. The case cover has an opening for loading basic process materials above the upper end surface of the backing roll, and an anchor-type mixer is fixed on the lower end surface of the backing roll.

Abstract: A method and apparatus is disclosed for treating pulp prior to being made into paper, which treatment is known as beating or refining. The method comprises feeding a slurry of the pulp to the narrow nips of grooved rolls at which the slurry of pulp is partially dewatered then almost simultaneously fragments of the pulp are subjected to a predetermined heavy pressure, then dispersed before being subjected to the same sequence until treated to the desired degree.
Abstract: An apparatus for cutting scrap tires and other waste products is disclosed. The apparatus includes a frame having a cylindrical anvil roll rotatably mounted therein. A pair of blade rolls are also mounted in the frame for rotation about corresponding axes which are parallel to the rotational axis of the anvil roll, the blade rolls being angularly spaced from one another relative to the axis of the anvil roll and being positioned about the periphery of the anvil roll. The blade rolls are each provided with a plurality of blades of predetermined diameter fixed thereto and rotatable therewith, the blades of one blade roll being at a low angle to the axis of that roll and the blades of the other blade roll being at a high angle to the axis of that roll, so that a tire passing between both blade rolls and the anvil roll will be cut into rhomboidal pieces that are nearly rectangular in shape during a single pass through the apparatus.
