Definitions

  • the invention relates to a device for crushing hard material with a lower disc-shaped body which is rotatable by a drive about a vertical axis, with an upper straight cone, the tip of which faces the disc-shaped body and whose axis to the axis of the disc-shaped body with formation a crushing area between the surface of the disc-shaped body and its conical surface is inclined, with a drive for rotating the upper cone in the direction of rotation of the lower disc-shaped body, with a device for displacing the upper cone along its axis and with one of the upper cone and the lower disc-shaped body enclosing housing in which an inlet for the material to be shredded on the top and an outlet for the shredded material on the underside is provided.
  • Such a device known from DE-A-26 06 485 is used for breaking hard material with a low coefficient of friction, as is required in the mining raw materials industry, in construction methods and in ceramics.
  • the disc-shaped body has a horizontal surface which forms a crushing gap on the side opposite the material feed with the conical surface of the upper cone, the size of which is set on the basis of the desired crushing size of the comminuted material, the cone is mounted to allow axially parallel suspension.
  • the material can be broken, but not gripped and ground, especially if the material has a low friction factor, since the angle of entry for the material into the size reduction area between the conical surface and the disc plane has an oval contour on one side and on the other other side has a straight contour.
  • the object underlying the invention is now to design the device of the type mentioned in such a way that it can not only break but also grind with its hard material to be shredded, even if it has a low coefficient of friction.
  • the size reduction area of the device according to the invention is located between the lateral surfaces of the cone and the hollow cone results in a curvilinear horn-shaped entry angle for the material to be ground between two oval working zones of the lateral surfaces, which reliably grips the material to be ground, for example mineral raw materials , and thus allows the material to be broken and ground even at high peripheral speeds of the cone and disc.
  • the cone angle of the hollow cone is expediently greater than that of the upper cone.
  • the upper cone is a device for adjusting the angle of inclination of its axis to the vertical axis of the disc-shaped body connected to the recess in the form of a hollow cone.
  • the device shown in Fig. 1 has a frame 1 which carries a housing 2 which is covered by a cover 3.
  • a cylindrical disc-shaped body 4 is arranged horizontally, the underside of which rests on a bearing 5 and can be rotated about its axis 20 by a drive 6.
  • the disc-shaped body 4 has on its top a depression in the form of a straight hollow cone 7.
  • a cone 8 is held via a bearing 9, which is displaceable and resiliently supported in the direction of its axis 21 by means of a device 22.
  • a shredding area 18 can be set between the outer surface 19 of the upper cone 8 and the outer surface of the hollow cone 7 in the lower disc-shaped body 4, the surface lines of which lie parallel to one another in the axial section, which is approximately the case with the arrangement according to FIG.
  • the intersection of the axes 20 and 21 lies in the tip of the cone 8, or form an acute angle with one another, as can be seen from FIGS. 3 and 4.
  • 3 lies in the sectional plane of the bases of the cone 8 and the hollow cone 7, the axes 20 and 21 intersecting at the tip of the hollow cone.
  • the tip of the acute angle between the generatrices of the cone 8 and the hollow cone 7 is in the region of the two tips of the cone 8 and the hollow cone 7, the axes 21 and 20 of which intersect in the almost collapsing tips.
  • the housing 2 at the top an inlet 16 for the material to be shredded and on the opposite side in the lower region an outlet 17 for the shredded material is provided.
  • the hard material to be shredded introduced into the device through the inlet 16 reaches the shredding area 18 between the outer surface 19 of the upper cone 8 and the outer surface of the hollow cone 7 in the disk-shaped body 4, both of which rotate in the same direction.
  • the material is broken and ground in the shredding area 18 and leaves the device through the outlet 17.
