Definitions

  • the invention relates to the attachment of grinding linings such as Grinding plates in drum mills with cylindrical or polygonal grinding cross-section by means of wedge-shaped elements which are fastened to the mill shell with screws.
  • the invention has set itself the task of solving the problems listed and is characterized in that between two grinding linings arranged in rings one, in particular formed by segments fastening ring is seen, which has a wedge-shaped cross section and which is fastened by screws to the mill shell.
  • Essential embodiments of this invention are specified in the subclaims.
  • the invention allows the grinding strokes and also the mill drive torque to be evened out, in that the individual successive rings of the grinding lining are each rotated by the same angle and in each grinding chamber an integer number of rotations or at a regular polygonal grinding plate lining, a number of twists reduced according to the number of corners is used.
  • the arrangement of the countersunk fastening rings removes the already ground fine material from the dead grinding and gently ground it by rubbing it against one another, thus improving the grain distribution in the ground material. Mixing is further increased by the knobs and or lifting strips on the fastening rings.
  • FIG. 1 shows a mill cross section with a square grinding cross section, the corners of which are rounded
  • FIG. 2 shows a longitudinal mill section
  • FIGS. 3 and 4 longitudinal sections through two different fastening segments
  • FIG. 5 shows a detail from FIG. 1 with the representation of the twist of the individual Rings.
  • the mill lining 8 is ring-shaped, the rings 1 or 2 being parallel or twisted relative to one another can be arranged.
  • the grinding plates of the mill lining 8 have oblique shear surfaces 9 on the ring surfaces, on which the material to be ground is brought out of the strand-like position and is thus additionally mixed. This is particularly important for wet grinding.
  • Wedge-shaped fastening rings 3 act on these shear surfaces 9, which are fastened by screws 4 to the mill casing 5 and wedge the grinding plates of the mill lining.
  • elastic intermediate layers 11 made of rubber or copper are provided between the fastening rings 3 and the shear surfaces 9.
  • the fastening rings 3 themselves consist of segments, the shape of which is shown, for example, in FIGS. 3 and 4. Because the inner ring surface deviates from the circular cylinder surface, the protruding knobs or lifting strips bring the regrind flowing in the trough between the rings 1 and 2 from the direction of flow and bring about mixing or increasing turbulence, thereby improving the grinding effect. At the same time, fine and coarse goods are separated, which reduces dead grinding.
  • the clamping of the grinding lining 8 or the rings 1 and 2 enables a continuous rotation of successive grinding cross sections, which is thus independent of the arrangement of the bores in the mill casing 5. This fact enables the greatest possible torque compensation with a polygonal grinding plate lining, whereby load fluctuations in the drive can be avoided. At the same time, the grinding strokes are evened out and thus the bearing loads are reduced. In this sense, it is particularly advantageous if the rotation of the first ring relative to the last ring of a grinding chamber is a multiple of 360, or for a regular polygonal cross section is a multiple of 360 ° divided by the number of corners.
  • FIG. 2 shows a part of a longitudinal section through a tube mill.
  • the shear surfaces 9 are of different sizes.
  • the cavity 12 between the milling lining 8 and the mill jacket 5 is covered by a foaming agent, such as, for example, polyurethane Foam filled, which creates sound insulation.
