Definitions

  • the invention relates to shredders consisting of a ring with a horizontal axis, driven in rotation around its axis by appropriate means, and at least one roller whose axis is parallel to that of the ring and which is placed inside the latter so that it can roll on its inner surface, which constitutes a grinding track, and comprising means elastic, such as springs or hydro-pneumatic cylinders, to press the roller on the ring, the grinding being effected by crushing the material between the roller and the ring.
  • a crusher is described for example in GB-A-2246720.
  • the invention relates more particularly to shredders of this type in which the roller is supported at its ends by two arms mounted on the mill frame so as to be able to pivot around the same axis parallel to the axis of the ring, the elastic means of pressure acting on said arms.
  • the object of the present invention is to provide simple means for limiting the use at an angle to the roll relative to the ring, while limiting the grinding pressures and, by therefore, mechanical stresses to acceptable values, as well as to contribute reduction of the oscillatory movements of the roller and its attachments.
  • the two arms are connected to each other by a shaft of torsion parallel to the axis of rotation of the arms.
  • This tree can be arranged along the axis of rotation of the arms or away from it, on the same side as the roller with respect to this axis or on the opposite side.
  • the mill shown in Figures 1 and 2 is constituted by a ring 10, with axis horizontal, which is supported by pads 12 allowing its rotation about its axis; these pads could be replaced by bearings or rollers.
  • the ring is driven in rotation by conventional means, not shown, for example by a motor and a reduction gear whose output shaft carries a pinion engaged with a toothed ring fixed on the ring.
  • the ring consists of a ferrule internally coated with wear plates which, in its middle part, form an annular grinding track 14.
  • the ring is closed at its ends by fixed bottoms to which are connected a feed chute, at one end, a discharge chute and a suction duct for pneumatic evacuation of fine particles, at the other end; these elements have no been shown in the drawings.
  • a roller 16 whose axis is parallel to the axis of the ring is placed inside this last so as to be able to roll on track 14 when the ring is rotated, in idling; when the crusher is in production, the roller rolls on the material layer covering the runway.
  • the roller is provided with two shaft ends 18 mounted in bearings 20 fixed on two arms 22 disposed outside the ring, on either side of the latter; the bearings 20 are fixed between the ends of the arms 22.
  • One of the ends of the arms 22 is fixed, for example by keying, on a shaft 24 whose axis is parallel to the axis of the roller and which is supported at its ends by bearings 26 mounted on chairs 28.
  • Hydraulic cylinders 30 connect the other end of the arms 22 to the frame of the crusher or foundations and allow the roller to be pressed onto the track. These cylinders are powered by a hydraulic unit which adjusts the pressure in the cylinders and, consequently, the force exerted by the roller on the layer of material covering the track.
  • the torsional resistance characteristics of the shaft 24 are such that it allows a certain angular movement of the arms 22 relative to each other. Its role is to limit the biasing of the roller with respect to the track when the roller is lifted by a Localized excess thickness of the material layer, avoiding applying local pressure excessive on the material layer and the track which could create stresses abnormal mechanics in the roller and the track. It also helps reduce oscillatory movements of the roller and arms 22
  • the shaft 24 serves both hinge axis for the arm 22 and torsion shaft.
  • the arms 22 could be rotatably mounted, independently of one of the other, on a tree arranged like the tree 24 and the torsion tree could be a tree tubular, coaxial with the first and whose ends would be fixed to the arms 22.
  • the shaft 24 could be placed outside of the ring.
  • FIG 3 shows another embodiment in which the torsion shaft is away from the axis of articulation of the arms 22 'supporting the roller 16', instead of being disposed coaxially as in the crusher of Figures 1 and 2.
  • Each arm 22 ' is here articulated on a shaft end 32 mounted on a chair 28 'and the two arms are connected together by a shaft of tubular torsion 24 'arranged opposite the roller with respect to the axis of articulation of the arms
  • This arrangement allows the torsion shaft to be placed outside the ring, which presents definite advantages.
  • the torsion shaft also works in bending and it is understood that the expression "torsion shaft" used in the description and the claims does not exclude this embodiment and does not imply not that the shaft works exclusively in torsion.
  • roller support arms and the torsion shaft could be adopted without departing from the scope of the invention as defined by the claims.
