Definitions

  • the present invention relates to crushers, and particularly to cone crushers of the type having two relatively rotatable conical surfaces defining between them a crushing zone of progressively decreasing cross-sectional area.
  • cone crushers the material being treated is known to undergo size reduction in a hollow space formed between an open-bottom hollow cone having a perpendicular axis and an eccentrically pivoted solid cone arranged underneath.
  • Both cones are provided with liners of particularly wear-resistant material, i.e. a bowl liner and a mantle which form the upper and lower boundaries of what is known as the crushing zone.
  • the mantle In cone crushers of hitherto known design, the mantle forms a rotary body with a generatrix which is either a straight line or composed of several straight-line segments.
  • the material undergoing size reduction in the lower portion of the crushing zone is to a large extent dispersed and the crushed particles cannot exert suflicient further crushing action on each other.
  • the discharged product frequently does not contain a large portion of small particles and the particles do not have the desired somewhat cubical shape as required today, particularly in road construction.
  • Another object of the present invention is to substan' tially improve the crushing action of such crushers.
  • Still another object of the present invention is to impede the dispersal of crushed particles in the lower portion of the crushing zone.
  • Yet another object of the present invention is to bring about an accumulation of the material being crushed in the lower portion of the crushing zone and thus to attain a more repeated comminution.
  • the mantle with depressions, particularly in the lower portion of the crushing zone. It appears particularly advisable to give these depressions 3,497,146 Patented Feb. 24-, 1970 the form of grooves arranged on several circles lying symmetrically to the main axis of the mantle.
  • the grooves can either be continuous and thus encircle the mantle without any interruption or they can be arranged on angularly offset arcs of one circle or of several adjacent circles.
  • FIGURE 1 shows the parts of a cone crusher which form the crushing zone and which include a head 1 with main shaft 2 which, when rotating, undergoes an eccentric movement.
  • the head 1 carries a mantle 3 which is a replaceable wear-resistant element.
  • a bowl liner 4 is attached to a bowl 5.
  • the material to be crushed, entering from above and discharged laterally, is reduced in size by the eccentric throw of the main shaft 2 carrying head 1 and mantle 3.
  • the mantle 3 is provided, according to the invention, with depressions in the form of grooves 7 which, in the example shown in FIGURE 3, encircle the mantle in the form of two uninterrupted circles 7 each concentric with the main shaft 2 and, in FIGURE 4, are shown as spaced, angularly offset arcs 7" of two such circles.
  • the depressions instead of having the shape of grooves, can be given any other desired shape such as circular, oval, polygonal, or other recess shapes. Tests have shown that they all cause the material being crushed to accumulate and consequently to be subjected to the size reducing crushing action more repeatedly, i.e. during a greater number of revolutions of shaft 2, than in designs hitherto used. The product thus contains a larger proportion of fine particles and a more favorable cubical particle shape.
  • the power train, the eccentric carrying the main shaft and causing its eccentric movement, etc., are of conventional design and therefore are not shown in the drawings.
  • a mantle for a cone crusher said mantle having the shape of a truncated cone with a planar upper surface
