A device and a plate-like grinding tool for grinding feed material that has a housing extending along an axis of rotation, in which a rotor rotationally driven about the rotation axis is arranged and includes a plurality of axially parallel grinding tools that are surrounded by a stator with stator tools. The effective edges of the grinding tools are arranged radially spaced from the stator tools by forming a grinding gap extending over an axial length of the grinding gap. The material is fed into the grinding gap on an inlet side and exits from the grinding gap on an outlet side. The axially extending effective edges of the grinding tools are divided in the axial direction into at least two first sections, each with a first radial distance from the rotational axis and into at least one second section with a second radial distance from the axis of rotation.

Disclosed is a straw crushing device capable of driving a sharpening structure, relating to the field of straw crushing. The straw crushing device includes a main housing, the main housing is internally provided with a crushing chamber and a suction chamber, a feeding nozzle is installed outside the main housing, and the feeding nozzle communicates with a feeding end of the crushing chamber. A spline transmission shaft is installed inside the main housing, and penetrates through the crushing chamber and the suction chamber. A driving motor is installed outside the main housing, and the driving motor is connected to the spline transmission shaft. A Y-shaped tool rest is installed on the spline transmission shaft, and the Y-shaped tool rest is located in the crushing chamber.

A process for separating carpet fibers from carpet backing uses a grinder of the type having a rotor with a plurality of vertically spaced cutter discs and a fan disc below the cutter discs. Sections of carpet are fed into the grinder which grinds the carpet, separating the fibers from the backing and breaking the backing into relatively small particles. The grinder is connected with a series of ginning equipment for removing the ground backing from the fibers.

A debris loader for comminuting or collecting leaves and debris comprises a vacuum tube connected to an intake assembly which connects to a blower housing. The blower housing contains a rotating impeller which creates suction through the vacuum tube and intake assembly drawing in leaves and debris. The leaves and debris are then discharged from the blower housing through a discharge opening or conduit. The intake assembly includes a cylindrical collar, to which a vacuum tube is attached, and a conical section which is connected to the blower housing. The diameter of the conical section expands from its connection with the cylindrical collar toward the blower housing. In a preferred embodiment the conical section is angled downward relative to the axis of rotation of the impeller and preferably at an angle of approximately thirty degrees.

An apparatus and method for processing a crop residue, which includes but is not limited to, destroying weed seeds present in the crop residue. The apparatus (10) comprises an elongate housing (12) having an inlet (20) for receiving crop residue N and an outlet (22) for discharging the crop residue. The apparatus (10) also has one or more rotors (24), (26) located in the elongate housing (12). Each rotor (24), (26) comprises a plurality of radially extending impact members (28a), (28b), (28c), (28d), (28e), (28f) which rotate with the one or more rotors (24), (26) and impact against the crop residue, so that lighter material of the crop residue is subjected to less impacts and denser material of the crop residue is subjected to relatively more impacts.
