SeposOscillating Screen

SHARE

THE SEPOS is an oscillating screen which effects an accurate granulometric separation of the treated materials, producing two (or more) sub-streams, which have a smaller or bigger particles than the diameter of the holes of the grid.

It is used in the most different situations, such as:

  • the cleaning of the glass;
  • the separation of mixed collections with the glass;
  • the cleaning of waste collection of the hollow bodies or paper;
  • the cleaning and the separation of collections of Solid Wastes Assimilable to the Municipal ones (RSAU).

It works as follows:

  • the material that has to be screened is introduced into the upper part of the machine, that is
  • disposed with a slight inclination forward;
  • the screening grid has a rotary-oscillating motion, mainly due to the effect of an eccentric;
  • this movement, coupled to the inclination, allows to make the materials advance and at the
  • same time to shake them, causing them to enter repeatedly in contact with the grid;
  • the fine materials fall from the holes of the grids and are collected in a bucket or belt conveyor;
  • materials that are larger than the holes in the output of the machine are set to further
  • exploitations;

The highlights of the SEPOS are:

  • the hight and accurate  quality of separation;
  • the rotary-oscillating motion, which does not cause kinking of the materials or the breakdown of
  • certain components of the flow or the clogging of the grids (problems that may occur with other
  • types of screens);
  • the very low noise level;
  • the absence of vibrations of the machine when it works.
