A hammer mill grinder includes a feed conveyor, a press wheel and a rotary hammer mill that is enclosed within a mill box. The mill box presents an intake opening for receiving feed material and a discharge opening for discharging reduced material. The press wheel is located adjacent to the mill box intake opening and is mounted at least indirectly to the mill box for vertical movement. The rotary hammer mill presents hammers that rotate, in cyclic succession, past the intake opening, the press wheel, an inside wall and a screen that is offset from the rotary hammer. The inside wall includes a contaminant bypass door that is able to open to allow a contaminant object to bypass the hammer mill prior to the screen and thereby exit the mill box around the screen to prevent damage to the hammer mill grinder.

A rotor for a comminution apparatus. The rotor includes a frame including an upper plate, a lower plate and wall elements. The rotor further includes an inlet opening in the upper plate and one or more outlets located between the upper plate and the lower plate. A distributor plate is arranged at an upper surface of the lower plate below the inlet opening and is arranged to launch the material towards a contact surface. The distributor plate includes a cavity being open at a lower surface of the distributor plate. The rotor further includes attachment means for maintaining the distributor plate at the upper surface of the lower plate. The attachment means are arranged to frictionally engage with a corresponding surface of the cavity and the attachment means enable the distributor plate to be repositioned into different wear positions.

Device for introducing incoherent material into a machine for processing incoherent material including an external body which is configured to be passed through by an incoherent material and which defines inside it a passage channel having an inlet aperture and an outlet aperture. The device also includes mobile deviation device pivoted to the external body and configured to selectively modify the cross-section of the outlet aperture.

A grinder device is provided with two sets of counter-rotating impact elements that pulverize the material via collisions, which represent impact forces twice as powerful through the doubling of the tip velocity. A continuous self-discharge of harder and heavier particles is provided to assure higher energy efficiency and a cleaner product that subjects the unit to less wear and tear. Outlet ports are provided on flange caps that are removably attached to the grinder device so that the position of the outlet port with relation to the position of a grinder stator is selectively modified. The device of the present invention can be provided in a container for integrating into an existing system or to operate as a standalone unit.

A rotary mill for grinding recycled glass materials into particles has a housing defining an impact chamber with a rotor in the chamber at the bottom of an inclined guide wall underneath the feed opening. The rotor has a plurality of axially extending, angularly spaced massive impact hammers so that the impact hammers impact and deflect the solid materials onto a plurality of shatter bars located at the peripheral wall. Each of the impact hammers has a leading blade element of a hardened steel which has a front face inclined relative to a bottom portion of the guide surface so that an outer edge of the front face is angularly advanced relative to an inner edge thereof.

An abrasion wear resistant distributor plate assembly is mountable to protect a rotor within a vertical shaft impact crusher for material fed into the rotor. A distributor plate is arranged so as to be resistant to the operational abrasive wear resulting from contact with a flow of crushable feed material through the crusher rotor. Attachment components are provided around a perimeter of the plate to facilitate mounting and decoupling of the plate at the rotor during servicing or replacement procedures.
