A vertical shaft impact crusher feed hopper distribution device arranged for feeding material to be crushed to a rotor of a vertical shaft impact crusher. The feed hopper distribution device is arranged to be mounted in a feed hopper that feeds material to the rotor and includes a supply channel that forwards material from an inlet opening arranged adjacent to an upper end of the supply channel to a hopper bottom opening arranged in a bottom of the feed hopper and communicating with the rotor. The supply channel has a cross-section that widens along at least a portion of the distance from the upper end to a lower end of the supply channel.

A control method of a crusher for elements to be recycled or disposed of, which includes a crushing assembly, to which the elements to be recycled or disposed of are provided, and pushers acting toward the crushing assembly to push the elements to be recycled or disposed of, includes a measuring step of the current absorbed by the crusher, a comparing step of the current value measured against a first predetermined value, and a reducing step of the push intensity of one or more of the pushers toward the crushing assembly in case the measured current exceeds the first predetermined value, the pushers being controlled separately from each other in order to partialize the push force and the push areas.

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).

The present disclosure is directed to a system and method for converting metal-containing waste wood material into livestock bedding having a reduced metal content. Waste wood, such as used or broken pallets is placed in a hammermill having a screen with holes of a larger diameter. The output of that hammermill is then placed in a hammermill having a screen with holes of a smaller diameter. A crossbelt system of magnets is passed across the waste wood to remove nails and other metal contaminates from the waste wood to produce a low metal content livestock bedding having particles of a consistent size.
