Abstract:
Method for reusing bituminous products (11), in particular bitumen containing roofing materials and membranes, wherein the bitumen containing products are placed in a second hopper (9), where a particulate material having a grain size between 5 mm and 35 mm is placed in a first hopper (5), and that in the bottom of the second hopper, conveyor means (10) urges the bituminous material into a mixing chamber (8), and that inside said mixing chamber a milling and/or crushing wheel (14) is arranged, which wheel engages and crushes/mills the material transported from the second hopper in an engagement zone, and at the same position as the wheel engages the bituminous material, the particulate material by means of a first conveyor (7) is fed into the engagement zone, and that the wheel's action will fragment the materials and at the same time mix the fragmented bituminous materials and the particulate materials, and transport the material past a sieve (15), where material having a particle size smaller than the sieve size will leave the mixing chamber and be collected and stored in suitable storage means.
Abstract:
A crusher comprises a crushing apparatus including a crushing rotor provided with a crushing bit for crushing target materials, a feed conveyor for conveying the target materials to the crushing apparatus, a pressing roller for pressing the target materials conveyed on the feed conveyor and introducing the target materials to the crushing apparatus in cooperation with the feed conveyor, and hydraulic cylinders for changing a relative positional relationship between the crushing apparatus and the feed conveyor, to thereby change a crushing angle formed between a feed direction of the target materials when the target materials are introduced to the crushing apparatus and a line tangential to the crushing rotor at a position where the crushing bit hits against the target materials. Since an angle at which the crushing bit cuts into the target materials is adjustable, crushed chips can be produced in a way flexibly adapted for various needs caused in sites by using a single crusher.

Abstract:
A wood crusher has body frame; a crushing apparatus installed on the body frame and a crushing rotor rotated in a crushing chamber. A feed conveyor for conveying wood to be crushed is installed on one side of the body frame in the longitudinal direction thereof and includes a drive wheel, a driven wheel, and a running member looped between the drive wheel and the driven wheel. A bottom-equipped hopper having side walls on both sides of the feed conveyor in the transverse direction thereof, and a bottom wall disposed under the feed conveyor has a guide member disposed in continuation with the bottom wall of the hopper at a position near the drive wheel of the feed conveyor to prevent wood pieces from accumulating near the drive wheel. This arrangement prevents the wood pieces from being dropped onto the ground during the crushing work.

Abstract:
An apparatus and method for shredding a block of material, the apparatus includes at least one cutting blade. A drive unit rotates the cutting blade about an axis, and a feed unit moves the block of material toward the cutting blade. The axis about which the cutting blade is rotated is generally perpendicular to the direction in which the block of material is being fed. In one embodiment, the block of material comprises a plurality of ribbons, the ribbons being stacked atop each other. In one preferred embodiment, the cutting blade comprises a serrated edge, and the distance between the teeth in the serrated edge is less than the thickness of each ribbon. In another embodiment, the shredding unit includes a plurality of blades on a rotatably driven drum.
Abstract:
A generally horizontal wood comminuter has a crosswise rotor with comminuting knives moving in a path of rotation and a crosswise coacting anvil. A feed works provides a material support surface and a power-driven feed member above it for feeding material toward the rotor. The rotor is driven in an uphill path of rotation relative to the feed works. Lift arms pivotally carry the feed member for swinging vertical movement toward and away from the material support surface. A crosswise deflector plate is carried independently of the lift arms and extends toward the anvil and a crosswise lift arm plate coacts with the deflector plate to contain fragmented material. The anvil and a grate retainer preferably are pivotal to move together from an operative to an inoperative position. A torque limiting device controls the drive of the rotor.
Abstract:
A sideboard assembly for an infeed system of a waste processing machine includes a sideboard for attachment to a sidewall of the infeed system of the waste processing machine. The sideboard assembly also includes a plurality of fasteners for removably attaching the sideboard to the sidewall of the infeed system of the waste processing machine.
