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.

The present invention relates to an industrial powder making device, including: a powder making cylinder body, spiked hammer arms, a front oblique hammer, vertical hammers, a hammer aim, a detachable rack, a detachable rack inner bulge, spiked blade arms, a front oblique blade, high-hardness wear-resistant alloy sheets, a blade arm, a rotating shaft, a rotating shaft groove, a clamping piece, a feeding port, a discharging port, bearings, a rotating power module, a liquid nitrogen storage tank, a pipeline, a valve, nitrogen input holes, a nitrogen output hole, a fine particle collection device and a disc bevel discharging control device.

A distribution member may include a distributing plate, a plurality of protecting plates and a second protecting plate. The distributing plate may be connected with a vertical shaft of the vertical shaft impact crusher. The distributing plate may have a first distributing surface having a conical shape, and a second distributing surface. The first protecting plates may be attached to the first distributing surface of the distributing plate. The second protecting plate may be attached to the second distributing surface of the distributing plate. Thus, the distribution member may be semi-permanently used by properly exchanging any one of the first protecting plates and/or the second protecting plate.

The invention relates to the method for milling and separation into fractions of solids and granular materials in a controlled airflow. The device for milling and separation of solids and granular materials consists of a round milling chamber with a system of pneumatic separation comprising of a vertical cylindrical body that has an uploading slot for solids and granular materials and unloading channels for the milled products of light, medium and coarse fractions. A rotating disc and a conical divider are located inside a vertical cylindrical body. The rotating disc has plates (hammers) and removable blades of different sizes and configurations. System of pneumatic separation consists of a milling chamber, an air slugcatcher, channels for the milled material, and a chamber of higher pressure. Such construction of the device allows to obtain products of a highest quality, and to improve the separation by dividing the material into three fractions: light, medium and coarse.
