Definitions

  • This invention relates to comminuting apparatus, and is particularly concerned with rolls of apparatus generally referred to as roller crushers, where two contra-rotating rolls are each provided with crushing members e.g. teeth on their peripheries.
  • the object of the present invention is to provide a roll for a so-called roller crusher which avoids the above disadvantages.
  • a roll for a roller crusher comprises a body portion in the periphery of which are formed a number of parallel longitudinal grooves a number of tooth bearing members, each having a surface to fit closely the periphery or part of the periphery of the body, and each having at least one projection from that surface of a shape adapted to fit the shape of a groove, and abutment means, at each end of the body, whereby the tooth bearing members are a sliding fit on the body and are located in their operative position by the abutment means, the engagement of the projections in the grooves and the abutting side-by-side relationship of adjacent tooth bearing members.
  • the tooth bearing members can be annular and formed with teeth at the outer periphery and a number of projections on their inner periphery corresponding to the number of grooves in the roll body. It is however preferred that the tooth bearing members are segmental, and formed with a number of dovetail-like projections corresponding to the number of dovetail-like grooves in part of the roll body periphery occupied by the segmental tooth bearing members.
  • eight grooves can be provided, equally spaced around the periphery of the roll body at 45° centres, and eight segments provided, each with one projection to fit one groove. Equally, for example, two segments each extending over 180° of the shaft or drum periphery could be provided, each having four projections to fit the four grooves in the 180 0 of the roll body periphery occupied by each such sector.
  • the roll body may be a one-piece construction, with the parallel longitudinal grooves extending along the length thereof, and whereby with identical tooth bearing annulii or segments, the teeth form aligned rows parallel to the axis of the shaft or drum. It may however be preferable in certain circumstances for longitudinally adjacent teeth to be offset, e.g., so that the rows of teeth are each angularly or helically disposed in relation to the axis of the shaft, or even with the teeth randomly positioned along the length of the roll.
  • the invention comprises a shaft, a number of roll body forming annulii adapted to fit on the shaft, each annulus at its periphery being formed with a number of parallel longitudinal grooves, and a number of tooth bearing members of the same length as the annuli each having a surface to fit closely the periphery or part of the periphery of a body forming annulus, and each having at least one projection from that surface of a shape corresponding to the shape of the grooves, each body forming annulus being adapted to be located on the shaft such that the corresponding grooves on longitudinally adjacent annuli, and hence corresponding teeth on longitudinally adjacent tooth bearing members, are offset.
  • each body forming annulus may have a central bore to receive the shaft, and the bore provided with a keyway to fit a key mounted on the shaft.
  • adjacent annulii can be positioned to set the rows of teeth in any required disposition, e.g., in straight rows of teeth in any required angular disposition in relation to the shaft axis, helically disposed along the length of the roll so formed, or even randomly disposed at the periphery of the roll so formed.
  • removable abutment means at each end of the shaft but a fixed abutment means could be provided at one end of the shaft, and a removable abutment means at the other.
  • the removable abutment means may be abutment plates secured e.g. by bolts, to the respective end of the roll body, but other means can be provided such as by locking an endmost tooth bearing annulus, or the segments of an endmost tooth bearing annulus, to the roll body.
  • the tooth bearing members can be held in position by abutment means in the form of clamping half-rings at each end of the drum or shaft.
  • the annulii and the tooth bearing members are again preferably held in position by abutment means in the form of clamping half rings at each end of the shaft.
  • abutment means in the form of clamping half rings at each end of the shaft.
  • the grooves can be formed by suitable machining.
  • the roll body (one-piece or annulii) can be formed by casting.
  • the one-piece body or the, annulii may be of a suitable tough material such as mild steel and keyed to an appropriate, relatively small diameter, alloy shaft.
  • the tooth bearing members are preferably cast from a harder wear and impact resistant tool steel, e.g., a manganese steel.
  • the teeth on the teeth bearing members may be integrally formed, and when the bearing members are segmental, each segment may be formed integrally with one or more than one tooth. It is equally possible for the teeth to be separately formed and subsequently secured in place. Thus, the teeth may take the form of relatively conventional picks, and the bearing members have secured to them the appropriate number of relatively conventional pick boxes. It is still further possible for the bearing members themselves to serve as the pick boxes, by forming in the bearing members an appropriate number of suitable angled bores to receive the shanks of relatively conventional picks.
  • each roll 1, 2 has a body provided with a number of longitudinally disposed parallel dovetail-like slots 6, and the teeth bearing members are formed with dovetail-like projections 7 to fit in the slots 6.
  • the teeth bearing members may be a number of annular rings 8 each formed on its internal periphery with a number of projections 7 to correspond with the number of slots 6 in the roll body.
  • the ring- like teeth bearing members can be slid along the roll from the other end into abutting side-by-side relationship, and when the requisite number of rings have been provided on the roll they are located in place by the securing of a further abutment plate 10 to the opposite side of the roll to the plate 9.
  • each ring is formed with a number of integral teeth 11 and the teeth are so formed and located on the rolls that those on the roll 1 face those on the roll 2, and such that when the rolls are located in the machine and caused to rotate, the teeth will grip and crush material falling into the nip of the rolls.
  • the tooth bearing members can be segmental.
  • a number of individual segments 12 are provided, each segment 12 being formed with an integral tooth 11 or indeed more than one tooth if so required, the requisite number of segments being employed to form a tooth bearing ring.
  • Each segment 12 is formed with a dovetail-like projection 7 to fit in a dovetail-like slot 6 in the roll surface.
  • an abutment plate 9 at one end of the roll the requisite number of segments can be slid on to the roll from the opposite end to form the required number of complete rings and the abutment plate 10 secured to the roll to hold the segments in position.
  • the invention provides for the replacement of the teeth of the rolls considerably more simply and with drastically reduced down time of the machine in comparison with the prior art.
  • the rolls 1, 2 may be removed from the machine, the abutment plate 10 removed, and the rings or segments with worn or damaged teeth simply slid off the roll and replaced by new rings or segments. With the abutment plate 9 repositioned, the rolls can then simply be replaced in the machine. It is equally feasible to allow for removal of the rings or segments with the rolls in-situ.
  • provision can be made for the disconnecting of the abutment plate 10 and for it to slide along the shaft by a distance at least equal to the width of the rings, when in segmental form. ⁇ ith, then, the abutment plate spaced from the end of the roll, the segments can be slid along the roll body into the gap between the roll body and the plate, and removed.
  • each segment 12 may have secured to-its outer periphery a relatively conventional pick-box 13 in which a point-attack pick 14 is located.
  • a still further alternative is shown where the segment itself serves as the pick-box, by providing an appropriately shaped bore 15 angularly disposed within the segment and in which the pick 14 can be located.
  • each roll is formed by a shaft 16 and a number of drum-like annulii 17 adapted to fit the shaft, each annulus at its periphery being formed with a number of parallel dovetail-like slots 6 to receive either a ring 8 or a number of segments 12 forming a ring, each provided with a corresponding number of dovetail-like projections 7.
  • each annulus is formed with a keyway slot 19 to locate it on the shaft 16 and by strategically positioning each keyway on the number of annulii involved, adjacent annulii can be set on the shaft such that the teeth on the ring or the segments on the adjacent annulii are offset.
  • the offsetting can be set to provide straight rows of teeth at any required angular disposition in relation to the shaft axis or to provide rows or teeth that are helically disposed along the length of the roll.
