A grinder for grinding relatively loose materials includes a reducing unit and a screen arrangement. The arcuate screen defines a plurality of tracks of apertures that extend in a cutting direction of the cutters. In some cases, only one respective cutter passes over each track and each cutter passes over only the respective one of the tracks. The width of a cutter may be greater than a width of the apertures of a track. The apertures of the screen arrangement may form chevron patterns. The screens may be clamped to a frame by coupling members extending through notches in the screen.

Impact reactor (1) for comminuting composite materials, comprising a cylindrical casing (2), in which a rotor (4) provided with impact elements (5) is arranged, wherein the impact reactor (1) is closed on the end face remote from the rotor (4) by means of a cover (7), wherein an suction opening (8) is assigned to the cover (7), wherein a classifying device (9) is assigned to the suction opening (8), and method of processing accumulator batteries, mineral wool and raw material.

A machine for comminuting laminated glass members, such as automotive windshields and architectural glass, comprises infeed rollers feeding the member over a breaker bar, where an impactor assembly breaks the glass into small fragments and the plastic disposed between layers of the glass member into larger fragments, so that a size-based separation may be employed. The speed of the infeed rollers is controlled responsive to the thickness of the glass member.

A method of processing organics having a relocatable trailer transporting a hopper, an infeed conveyor, an organics separation unit, an organics conveyor, an inorganics waste conveyor, and a control panel between processing locations of organic material. The control panel regulates the operation of the infeed conveyor, the organics separation unit, the organics conveyor and the inorganics waste conveyor. Following completion of processing the components carried on the trailer may be cleaned and the trailer supporting the processing components may be moved to another processing location.

A beater wheel for a pulverizer mill is provided. The beater wheel includes a rotatable hub disc having apertures defined therethrough and a ring disc having respective apertures defined therethrough, and a plurality of tubular ribs, disposed therebetween and weldingly coupled thereto at a tubular first end to the hub disc and at a tubular second end to the ring disc to define respective weld joints thereat. Each respective aperture in the hub disc and ring disc are sized and disposed to allow direct access therethrough to at least one respective weld joint at the respective interior surface of the first and second tubular ends for inspection and testing.

A delumper includes a housing defining a chamber in which edible material is received. The housing includes a screen having a plurality of holes and a plurality of inwardly extending fingers. The holes are sized such that edible material of a first diameter is capable of passing through the holes and edible material of a second, larger diameter is incapable of passing through the holes. The fingers are arranged in at least a first row, and the first row is located at or between a 5:00 position and a 7:30 position. The delumper further includes a rotatable shaft including a plurality of paddles spaced along a length of the shaft. When the shaft rotates, each of the paddles passes between adjacent fingers of the first row such that edible material located within the chamber is forced into contact with the fingers and cleaved by the paddles.
