An apron return assembly having a pump that is adapted to convey a fluid, an apron actuator having an apron actuator cap side and an apron actuator rod side and being in fluid communication with the pump, an accumulator that is in fluid communication with the apron actuator cap side, a reservoir that is in fluid communication with the apron actuator, and a tension rod having a frame end and an apron end. In the preferred apron return assembly, the apron actuator and the tension rod are adapted to move the apron between a closed position and an open position. A method for moving the apron from the open position to the closed position.

The present invention has developed, unlike a conventional technology, an apparatus and a technique for rind, inside and scrap separation, which has been the greatest impediment to the mass production of high-quality paper-making pulp, thereby enabling the production of high-quality pulp, enables produced, unbleached pulp to be used as a raw material for manufacturing industrial packaging paper because of the excellent strength of the pulp, allows bleached corn chemical pulp to be suitable for the manufacture of toilet and facial papers and tissues, and can be applied to various paper-making techniques by mixing pulps, having different characteristics, such as needle bleached chemical pulp, leaf bleached chemical pulp, and bleached chemical thermomechanical pulp (BCTMP).

Processing device for processing material to be processed, comprising a stationary housing with a feed opening for feeding material to be processed and comprising a rotor which is arranged in the stationary housing so as to be rotatable about a substantially vertically extending rotor axis, wherein, adjacent to the outer circumference of a base element of the rotor, a plurality of bearing pins are fastened to the base element, with a processing element being mounted on each of said bearing pins, and wherein the radially outer ends of the processing elements form a processing gap with an inner circumferential wall of the stationary housing, characterized in that the free ends of the bearing pins are connected to one another via a connecting disc.

A pulverizer has arms connected to a vertically oriented rotating shaft at hubs. The arms are angled relative to radians extending from the shaft to be canted or offset. Pads can be oversized relative to the arms while being one of coplanar with the arms or recessed while possibly also having their radially inward face(s) angled to assist in resisting catching material thereon. A mechanical fuse connection can assist in connecting arms to the hub to prevent dangerous situations as well.

A plant for the processing of waste includes an outer housing and a grinding cell, in which a grinding chamber is defined having at least one inlet opening for introducing the waste to be processed, and at least one outlet opening for discharging the material resulting from waste processing. The openings are associated with a corresponding closure element, adapted to isolate the grinding chamber from the outer environment. The outer housing defines therein a space receiving the grinding cell and integrally surrounds the grinding cell, and in which the space is accessible through at least one door.

A process for treating a fines stream in a material recover facility (MRF), comprising: providing an MRF fines stream comprising breakable material and ductile material: subjecting the MRF fines streams to a one-pass kinetic pulverization stage to produce a pulverized material comprising a size-reduced fraction derived from the breakable material and an oversized fraction derived from the ductile material; withdrawing the pulverized material from the kinetic pulverizer; and subjecting the pulverized material to separation to produce a size-reduced stream and an oversized stream. Also provided is a system comprising a kinetic pulverizer, a pulverizer conveyor and a screen operatively coupled to the pulverizer conveyor to receive a pulverized stream and produce a sized-reduced stream and an oversized stream. The system can also include a magnetic separator and a dust collection system respectively located upstream and downstream of the kinetic pulverizer.

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.

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.
