A horizontally fed disk grinding system includes a tray coupled to a trailer for receiving bulk material. The system further includes a grind hub coupled to the trailer and a cutter disk coupled to the grind hub. The grind hub is structured to rotate about a grind hub axis and the cutter disk is structured to rotate about a cutter disk axis and about the grind hub axis. A grind ring is coupled to the trailer and is structured to slide to engage the grind hub during use. A plurality of plates are coupled to the tray and structured to oscillate to feed material from the tray to the grind hub and the cutter disk, where the material is reduced to particulate form. The grind hub further includes an outlet and a conveyor rotatably coupled to the trailer to convey the particulate material away from the outlet to a selected location.

The present disclosure discloses a double-material grinder for grinding materials comprising a housing and a grinding component. The housing comprises a first housing and a second housing removably attached to each other to form a closed cavity. The first housing comprises a vertical baffle. The grinding component comprises a first grinding unit arranged in the first chamber and a second grinding unit arranged in the second chamber. A blanking gap of the first grinding unit corresponds to the first blanking hole. A blanking gap of the second grinding unit corresponds to the second blanking hole. The second housing comprises a driving unit to drive the first grinding unit and the second grinding unit. The mouth for adding materials is open and substantially larger than those of other two-material grinders so that replenishing of materials becomes easier and mixture of different materials is completely prevented.

A device for comminuting ore and/or slag is contemplated. The device may be comprising an ore feeding unit for feeding ore which is to be comminuted to a first pulverizer, said first pulverizer being composed of at least of two comminuting elements which can be moved relative to each other, said elements forming together at least one comminuting space for the ore which is to be comminuted, such that, by a relative movement in the form of a rotation about the rotational axis of at least one of the two comminuting elements the ore which is to be comminuted is at least partially pulverized. One or more accelerating elements, in particular protrusions, are provided on at least one of the comminuting elements, said accelerating elements being arranged in particular on the end face of at least one of the two comminuting elements and accelerating and comminuting the ore to be comminuted by the rotation of one of the two comminuting elements. An intermediate space is provided between the two comminuting elements and/or in at least one of the two comminuting elements, through which space the pulverized ore, during the rotation, is transported from the center of rotation toward the outside and away from the two comminuting elements. At least one of the two comminuting elements is operatively connected to a hydraulic spring pressure device, said hydraulic spring pressure device being designed such that the comminuting element to which it is operatively connected is variably resiliently mounted in the direction of the other comminuting element depending on an adjustable hydraulic spring pressure control unit.

A rotor rotation device the rotor of a crusher includes a drive mechanism comprising a worm shaft and corresponding worm wheel. The worm wheel can selectively be coupled to said rotor in order to effect controlled rotation of the rotor, e.g. to facilitate maintenance of the crusher. The worm shaft cannot be back-driven by the rotor which allows the drive mechanism to serve as a lock against unwanted or uncontrolled rotation of the rotor.

A solid material grinding method and device with an adjustable discharge size includes a grinding disc housing, and a movable grinding disc and a stationary grinding disc provided in a grinding disc cavity of the grinding disc housing coaxially with grinding surfaces opposite to each other. The movable grinding disc is driven to rotate in the grinding disc housing, thereby grinding materials between the movable grinding disc and the stationary grinding disc. The movable grinding disc is further connected to a pushing mechanism, and the pushing mechanism adjusts the distance between the movable grinding disc and the stationary grinding disc in a push-and-pull manner. A top rectifying blower and a side edge rectifying blower respectively blow gas from an upward side and a lateral side of the movable grinding disc and the stationary grinding disc. A central rectifying blower blows gas to the center of the stationary grinding disc.
