The present invention relates to a device for treatment of a material mixture consisting of substitute fuel and impurities, having a vertically aligned central feeder (1), a separating unit (2) arranged underneath the central feeder (1), a rotor mill (3), wherein the rotor mill (3) is arranged above the separating unit (2) and surrounds the central feeder (1), a flow device (4) for generating an upwardly directed gas flow, wherein the rotor mill (3) has a multistage design, and a respective separating device (6) is arranged between the stages (5.1, 5.2) of the rotor mill (3), wherein material mixture not held back by the separating device (6) is further comminuted in the following stage (5.2).

A pick system includes a holder and a pick assembly. The holder includes a first end, a second end, and a bore extending between the first end and the second end and defining a longitudinal axis. The surface of the bore may be tapered so that the diameter of the bore proximate the first end is greater than the diameter of the bore proximate the second end. The pick assembly includes a shaft. The shaft is received within the bore of the holder along the longitudinal axis, and the shaft may be tapered to mate with the bore.

An apparatus for rotationally grinding, pulverizing, or comminuting bulk materials. The apparatus comprises a material processing component fed at an input end by a hopper. The material enters the material processing component for processing and is propelled out of an output end through an outlet into a tray or piping. The material processing component comprises a cylinder with an exterior insulating compartment and a replaceable inner liner. The cylinder defines a horizontal stationary work area. A rotatable shaft penetrates the cylinder along an axis of the working area. A plurality of working bodies are attached to the shaft in a narrowing helical orientation that also narrows in distance between working bodies from front to back. The working bodies are configured to comminute the material and direct it toward the outlet as the material passes through the working area.

A multi-piece hammer for use in a reducing machine. The multi-piece hammer includes a base to be mounted to the reducing machine, a replaceable tip to be mounted to the base and to impact the material to be reduced, and a retainer to secure the replaceable tip to the base. The replaceable tip has a cavity with a single rail or groove that corresponds to a single groove or rail on the base.

A device to fragment solidified bulk material is disclosed. The device comprises a hydraulic motor, a stationary assembly and rotating assemblies, wherein the rotating assemblies includes, a rotational upper whip mount assembly adapted to rotate in a direction, a rotational middle assembly perimeter adapted to rotate in the same direction as the rotational upper whip mount assembly, and a rotational lower whip mount assembly adapted to rotate in a direction opposite the rotational direction of the upper whip mount and middle perimeter assemblies, and a plurality of flails configured to fracture hardened, solidified bulk material while balancing the torque forces to more accurately keep the dual whip-head head in a desired location when operationally engaged with the bulk material.

A bi-metallic swing hammer for a particulate size reduction system includes a shank portion. The shank portion has a first end having a mounting portion for attachment to a wheel assembly of the particulate size reduction system, a second end defining a shank tip, and a face surface extending from the first end to the shank tip. The bi-metallic swing hammer includes a wear pad cast to the face surface of the shank portion. The wear pad extends from the shank tip to the first end of the shank portion up to the mounting portion. A method of constructing a bi-metallic swing hammer for a particulate size reduction system includes casting a wear pad and a shank portion together to bond the wear pad to the shank portion.
