A vertical shaft impactor includes an impacting assembly that is configurable in a number of different ways, depending on the material to be processed by the impactor. The vertical shaft impactor includes an impacting chamber and an impacting assembly disposed in the chamber. The impacting assembly includes a number of rotors supported on a shaft, with the locations of the rotors being adjustable along the shaft. The rotors include adjustable structures for working and reducing materials in the vertical shaft impactor.

A mill includes a generally vertical, rotatable shaft having at least one set of cutter blades driven thereby and a fan assembly mounted on the shaft below the cutter blades in position to receive output therefrom. The fan assembly includes a fan disc secured to the shaft and rotatable therewith. A plurality of fan blades is secured to the fan disc in a generally radial orientation. A terminal portion of the mill includes a gradually, radially expanding outer wall configured in a volute form. The expanded outer wall decreases wear and increases efficiency of discharge and airflow through the mill.

A method of manufacturing pulp using corn stalks may include cutting the corn stalks into pieces having a length of 10 to 60 mm, separating and discharging the cut corn stalks into rind and pith using a separation unit while crushing the cut corn stalks, pretreating the corn stalks by filtering the rind and pith of the corn stalks and flakes of the rind, removing a portion of hemicellulose of the rind, and cooking the rind from which the portion of hemicellulose has been removed, using caustic soda and sodium carbonate.

A system for maintaining a downward force on a central shaft of a cone crusher having a stationary frame, including a disc fixedly mounted to the frame, the disc having a centrally-disposed aperture with a first diameter. A plate is mounted to an end cap, the plate having a second diameter that is greater than the first diameter. The plate is disposed distally of the disc and the end cap is disposed proximally of the disc. A housing is fixed to the central shaft and biased away from the end cap wherein a downward bias is imparted to the central shaft.

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

A system is disclosed. The system includes an impact processor comprising an inlet and an outlet, a secondary classifier comprising an inlet and an outlet, the secondary classifier being downstream of and coupled to the impact processor, a recirculation mixer valve downstream of and coupled to the outlet of the secondary classifier, and a recirculation line coupling the outlet of the first secondary classifier to the inlet of the impact processor.

An abrasion resistant wear plate is mountable within a rotor or a vertical shaft impact crusher to protect the rotor from material fed into the rotor. The wear plate includes a main body that mounts and supports at least one abrasion resistant insert to define, in part, a contact face over which feed material is configured to flow.

An articulable-arm-mountable pulverisation apparatus (10) is provided for reducing material size. The apparatus (10) includes a material-receiving housing (12) having a material-processing chamber (22a), a discharge outlet portion (22b), and a drive-unit compartment (22c). The apparatus (10) also has an articulable-arm mounting element (18) for releasably attaching the apparatus (10) to an articulable arm of an excavating machine. The apparatus (10) also includes a rotatable element (56) in the material-processing chamber (22a). The rotatable element (56) has a side surface which, together with an interior surface of the material-processing chamber (22a), forms a tapering pulverising material flow-path towards the discharge outlet portion (22b). A unitary drive unit (16) is provided in the drive-unit compartment (22c). The drive-unit compartment (22c) has an openable access cover (50), whereby the unitary drive unit (16) can be slidably removed in an axial direction as one-piece from the drive-unit compartment (22c) for utilisation of the unitary drive unit (16) in a different apparatus.
