Abstract: Exemplary embodiments are for a system for crushing a material that may include a compaction chamber and a screw assembly that generally extends between the proximal and distal ends of the compaction chamber. A portion of the screw assembly increases in diameter along a length of the shaft of the screw assembly such that the system is configured to crush material between the compaction chamber and the portion of the screw assembly that increases in diameter. The portion of the screw assembly that increases in diameter may be integral with the shaft of the screw assembly. An exemplary embodiment of the system may also include at least one wear member that is removably associated with the distal portion of the compaction chamber such that the wear member may assist with the crushing of material.

Abstract: The invention relates to a roller mill having a grinding pan which is rotatable about a mill axis, on the grinding track of which grinding pan stationarily disposed grinding rollers roll and thereby define with their circumferential surfaces on the grinding track a running circle with an inner diameter and an outer diameter, and having a grinding material distributor for grinding material to be reduced, which is arranged as an elevation in the centre of the grinding pan coaxially with respect to the mill axis and rotates with the grinding pan.

Abstract: A gyratory crusher has an outer shell, which is attachable in a frame having a frustoconical supporting surface, which is facing obliquely downwards and inwards. The outer shell has on the outer surface a collar, which has outer lugs, which are movable, from below, past the supporting surface and between inner lugs of a ring. The inner and outer lugs have mutually corresponding contact surfaces, which are adapted, by relative rotation of the ring and the outer shell, to be positioned opposite each other and, upon lifting of the ring, to lift also the outer shell so that a lower portion of the outer shell abuts the supporting surface of the frame. The contact surfaces of the inner and outer lugs are arranged such that lifting of the ring causes the outer lugs to be lifted by means of the inner lugs and brings the inner and outer lugs into radial abutment against each other.

Abstract: A hydraulic crusher includes crushing arms, a crusher body having a hollow portion extending in the longitudinal direction, and hydraulic cylinders. The hydraulic crusher includes four first hydraulic hoses which have proximal caps connected to ports of the crusher body and extend toward the distal side in the longitudinal direction in the hollow portion; four second hydraulic hoses which have proximal caps connected to ports of the hydraulic cylinders, and extend into the hollow portion and then toward the distal side in the longitudinal direction while being curved; and a clamp or the like serving as a joint member movable in the longitudinal direction, the clamp connecting distal sections of the first hydraulic hoses with distal sections of the second hydraulic hoses.

Abstract: A pulverizer upper gearbox bearing assembly for a mill includes a bowl hub having a stepped hub defining a first bore to receive a shaft therethrough and a bowl extending radially outwardly therefrom defining a cavity between the stepped hub and bowl, the stepped hub having a first outside diameter extending to a second outside diameter, which in turn extends to a third outside diameter along a longitudinal axis of the first bore, the first outside diameter larger than the second outside diameter, which is larger than the third outside diameter; a thrust bearing disposed around the first outside diameter, the thrust bearing having an upper washer and a lower washer, the upper washer having an interference fit with the first outside diameter of the bowl hub; a roller bearing disposed around the third outside diameter, the roller bearing having a separable inner ring from an outer ring and a surrounding cage and roller assembly; a mill base hub extending into the cavity between the bowl and stepped hub, the mil

Abstract: An office device. The device includes: a paper shredder, an ink dispensing device, a housing, a display device, a user interface, a control module, a combination device, an entry slot, a transparent member, and a bin. The ink dispensing device disperses ink over paper shredded by the paper shredder. The display device is hingedly coupled to the housing. The user interface is slidably coupled to the housing. The control module communicates with the display device and user interface. The combination device includes a copier device, a fax device, and laser printer device. The entry slot permits paper to be fed thereto. The transparent member covers a portion of the entry slot. The bin is disposed within the housing. The display device is a monitor. The user interface is a keyboard. The paper shredder includes a rotating vertical shredder and a rotating diagonal shredder.
