Definitions

  • the present invention relates to a mineral crusher for reducing a mineral material, comprising a rotating roller having a plurality of projecting impact members.
  • a rotating drum has a plurality of blow bars, impact bars or teeth, which as the roller rotates at high speed, impact large lumps and particles of the mineral causing reduction in mineral particle size.
  • the blow bars throw the mineral against a breaker plate, spaced apart from the roller. Reduction of the mineral material occurs by impact with the blow bars, impellers or teeth and by impact with the breaker plate.
  • a prior art mineral crusher assembly comprising a roller 1 arranged to rotate under power about an axle 2, the roller comprising a plurality of impeller bars 3 extending radially outward of the roller, an outer casing 4 comprising first and second opposite upright sides, a front panel 6, a back panel 7 and a roof, the roof being lined with a plurality of breaker plates 8, 9, 10 against which the mineral is thrown, and a grid 11.
  • the mineral On entering an open mouth 12 of the crusher, the mineral encounters the rapidly rotating roller 1 and is reduced by impact with the roller, and particularly the impeller bars 3.
  • the impeller bars throw lumps of the material against the breaker plates 8, 9, 10 and the mineral repeatedly bounces backwards and forwards between the roller and the breaker plates, being reduced on every impact.
  • the mineral On reaching the rear of the crusher, the mineral drops down under gravity, and under force imparted by the rotating roller, onto the grid 11. The reduced mineral drops out from underneath the crusher into a hopper, conveyor belt or the like.
  • the maximum size of particle to which the mineral is reduced is largely determined by the distance between the final breaker plate 10 and the roller.
  • the position of the final breaker plate 10 with respect to the roller is adjustable.
  • the resulting reduced mineral has a range of particle sizes varying from various small particles eg. grains of sand, through aggregate of 10mm, 20mm average particle size, up to the maximum particle size, eg. 100mm.
  • the reduced mineral may be separated and graded into different sized particles as required on exiting the crusher.
  • the grid 11 comprises a plurality of substantially parallel bars spaced apart from each other.
  • the position of the grid with respect to the roller may be adjustable, and the grid may be swung away from the roller, being swung from a hinge.
  • the grid 11 is shown schematically in Fig. 3 herewith.
  • FIG. 4 Another prior art crusher, shown in Fig. 4 herewith, operates similarly as the crusher of Fig. 2, except that the final reduction occurs by the hinged grid section 30 completely underneath the roller, between the front and rear panels of the casing.

Abstract

La présente invention concerne un concasseur de matières minérales équipé d'un cylindre (50) portant une pluralité de barres de projection servant à projeter de la matière minérale contre un plateau collecteur (100) sur lequel s'accumule un amoncellement de matière minérale. La matière projetée contre l'amoncellement de matière minérale se brise sous l'effet du choc contre la matière amoncelée. Le plateau collecteur, qui est réglable de façon à régler la taille de l'amoncellement de matière, est également inclinable de façon à s'écarter du cylindre avec un effet de ressort lorsque des objets hors calibre, tels que des morceaux de métal ou des blocs de bois, traversent le concasseur. Cet agencement présente l'avantage de provoquer une moindre usure du plateau collecteur (100), ce qui en nécessitera des remplacements moins fréquents. La fabrication de ce plateau collecteur (100) est relativement facile.
