  • Patent number: 11498768
    Abstract: A method 10 of refurbishing a bucket wheel reclaimer (BWR) 41 having structural frame 68, a chute 66 supported by the structural frame 68, a yard conveyor 42 for receiving material from the chute 66 and an impact table 64 supported by the structural frame 68 below a portion of an upper run 44 of the yard conveyor 42. The method includes a step 12 of decoupling a current impact table 64 from the BWR structural frame 68. The impact table 64 is lowered at step 26 from the structural frame 68. Thereafter at step 14 the current impact table is moved laterally away from and to one side of the yard conveyor. At steps 16 and 18 a fresh impact table is moved laterally to a location beneath the upper run 44 of the yard conveyor and coupled to the BWR 41.

  • Publication number: 20210355650
    Abstract: A bucket wheel assembly (40) includes a structural frame (42) that in use forms a structural part of the boom of a bucket wheel reclaimer. The structural frame (42) supports a bucket wheel (44) having a plurality of attached buckets (46); a ring chute (48) and an associated discharge chute (50). The bucket wheel (44) is attached to the middle of shaft (51), which is supported by two bearings (52). The drive unit is attached to the shaft (51) to provide the rotation torque, and the drive unit is also attached to the structure (42). The structural frame (42) couples to a portion of the boom and transfers the assembly load to the boom when the reclaimer is in operation.

  • Patent number: 10399081
    Abstract: The present invention relates to a crushing roll for a roll-type crusher has a shaft with at least one groove extending in the axial direction on its lateral surface, to receive formed elements. The formed elements serve to retain the crushing shells, for which purpose the formed elements form a form-interlockingly engaging combination with the groove in the shaft, in the radial direction. A “form-interlockingly engaging combination in the radial direction” is understood here to signify means of blocking of movement of the formed elements in the radial direction of the shaft. In this way, it is possible to anchor the crushing shells in the grooves by means of the formed elements.

  • Patent number: 10307764
    Abstract: The present invention relates to a machine frame for a roll crusher that has two side walls and two end walls, where the mentioned end walls accommodate the storage of the rolls. The end walls are split horizontally in the area of the mounting of the rollers, and vertically between the mountings of the upper part. One advantage is that to remove a roller, removal of the respective upper end wall is sufficient. In a preferred embodiment of the invention, the adjacent upper parts of the end walls do not touch. An advantage of this is that tilting of the end wall upper parts among each other or in contact with the side walls is prevented during removal. Furthermore, the gap resulting from the distance between the front wall upper parts in the preferred embodiment would be sealed, with the advantage that no material and dust can exit.

  • Patent number: 9169078
    Abstract: The invention relates to the design of driving, deflecting, and tensioning drums for conveyor belts, comprising a one-piece drum jacket or a drum jacket (1) comprising a center drum body (10) and two bearing pieces (11, 12) attached to both sides of the center drum body. All three components of the drum jacket (1) are provided with flanges on the sides facing each other and screwed together at said flanges. Each of the two bearing pieces (11, 12) has an annular bearing seat for rolling-element bearings on the outside. Each of the two rolling-element bearings is accommodated on the outside by a bearing shield (3, 4), wherein the one bearing is a fixed bearing and the other bearing is a floating bearing. In a first embodiment, a direct drive (2), the rotor of which directly drives the drum jacket (1), is provided as a drive.

  • Patent number: 6948779
    Abstract: A mining member designed as a cutting roller for a continuously operating surface miner for mining mineral raw materials of high strength. The roller body is equipped for this purpose with mini-disk bits of identical design. Since different conditions occur over the entire width of the roller during the separation of the material from the soil, the roller body is designed correspondingly, and the arrangement of the mini-disk bits is adapted to these conditions. The mini-disk bits in the edge areas are placed at a greater density than are the mini-disk bits (7) in the middle area. In addition, mini-disk bits are directed obliquely toward the outside as free-cutting bits at the two outer edges of the cutting roller. The height of the mini-disk bits is selected to be such that their individual virtual rolling paths together form a virtual cutting roller body, which comprises a middle cylinder, which is joined on both sides by outwardly tapering frusta.

  • Patent number: 6264022
    Abstract: A cover belt conveyor with a basic belt guided by three support rollers (9) arranged in a trough-shaped pattern. To guarantee the ability of such a cover belt conveyor to function at different amounts of material to be conveyed, four pressure rollers (11) are arranged over the entire width of the cover belt (3) in the case of a basic belt (2) with a troughed support roller station comprising three support rollers (9) such that the two middle pressure rollers (11a) always act on the area opposite the middle roller (9) and the two outer pressure rollers (11b) of the cover belt (3) act on the area opposite the two oblique support rollers (9). The pressure rollers (11) are arranged individually pivotably on the frame of the conveyor and they can thus automatically adapt themselves to the particular volume of material to be conveyed between zero and a maximum and apply the necessary pressure on the cover belt (3) in the process.
