Definitions

  • the feed material passes 1 by means of feed bunker or conveyor belt 2 on the screening machine 4, promoted here on the first screen deck, on this first screen surface, the so-called oversize is screened through the discharge chute 11.
  • the screened material falls by gravity on the return conveyor, 7 transported this conveyor belt
  • the material at the beginning of the underlying screen surface, this screen surface gets 100% material, the previously screened material.
  • the second screening takes place, About the sieve surface 6, the oversize is excreted over 11.
  • the screened material passes by gravity on the return conveyor, at the beginning of the third screen surface 6 to 100%.
  • the oversize is excreted via the chute 11 again.
  • the third screen surface from above again takes place a 100% screening.
  • the oversize is excreted via the chute 11 as before.
  • the screened material falls by means of conveyor belt 7 to 100% on the bottom deck from above.
  • the last screening is separated via the chute 11.
  • the final product, which is screened out on the last screening surface 6, is discharged via the outlet chute 5.
  • the invention is based on the task to develop a screening machine, which always ensures a 100% utilization of the screen surfaces in a multi-deck screening machine. For example, it can be assumed that with a 4 Decker sifting machine of a conventional type, with a screening of 5 grains for a feedstock from the top in the last 4th screening deck only about 50% of the screening surface is available for screening, this is natural the thing. Because the feed material runs from approx. 0 to 40 mm in the task in a 4 Decker sieve up to the outlet with approx. 30 degree inclination. This evil is offset by the invention.
