Definitions

  • the invention relates to a device for sieving crushable materials or materials having particles of different sizes, with at least one screen surface, which is movable by means of a drive device. Furthermore, the invention relates to a method for screening of comminuted materials or materials having particles of different sizes, in which a screen surface is moved by means of a drive device.
  • the solution according to the invention results in a very advantageous movement of the sieve surface, which results in the materials to be screened being placed on the sieve surface being relatively high and due to The gravitational force will hit the screen again at a correspondingly high speed, where it will be crushed. This results in a relatively short time a very effective crushing of the material to be screened.
  • the circular or elliptical movement of the screen surface leads to a sinusoidal movement of the material to be screened on the screen surface. This sinusoidal movement even stubborn glued or solid materials are loosened and can be easily sieved.
  • the drive device engages with the at least two drive elements at at least two mutually spaced articulation points of the screen surface, whereby the movement introduced by the drive device into the screen surface takes place over the entire screen surface.
  • the material is alternately loosened and compressed again from the screen surface and onto the screen surface, which further enhances the screen effect strengthened.
  • the material is compressed and loosened or pulled apart during the downward movement.
  • the drive element mounted via the movable bearing can perform movements to a certain extent in the direction of the other drive element, whereby production tolerances and loads occurring during operation are compensated and vibrations of the screening device are avoided.
  • no degrees of freedom are allowed, thereby preventing undesirable movements of the screen surface, so that ultimately the described, predetermined, at least approximately circular or elliptical path can be maintained.
  • a very advantageous development of the invention may consist in that the guide element is designed such that it guides the movable element in the direction of a straight line connecting the two articulation points.
  • the guide element with the screen surface and the movable member is connected to the drive element, resulting in a structurally very simple solution that ensures the described guide element of the screen surfaces.

  • the drive elements move the pivot points on a circular or elliptical path with a diameter of at least 50 mm. It has been found that such a minimum diameter of the movement of the articulation points with respect to the sieving result is very beneficial. In principle it holds true that a larger diameter of the circular movement leads to a greater throwing height of the material located on the screen surface, as a result of which it has a higher speed when it strikes the screen surface and therefore undergoes greater size reduction. In this case, a diameter of at least 80 mm, preferably at least 100 mm, even more advantageous.
  • the drive elements are formed as connected to respective rocker arms drive shafts, which are connected to a respective eccentric driven such that there is a non-rotating oscillating movement of the drive shafts.
