Definitions

  • the invention relates to Deinkingware with a share of newspapers, a share of magazines and a share of Impurities.
  • the deinking material serves as a raw material for newsprint and higher quality graphic papers and is generally in a pulper dissolved or processed into a fiber suspension (pulp).
  • the length of stay a pulper for the resolution of standard deinking products reaches up to 20 Minutes.
  • the pulp is pumped through coarse sieves and a cleaning to Removal of undesirable components during manufacture, during Use or consumption of paper or processing the turn or the quality of the new paper impaired fed.
  • the undesirable ingredients include including coating material from milk carton box, films, staples, Iron splinters from the wear of processing machines, Styrofoam made of packaging materials and printed matter.
  • the cleaning includes sieve, Washing and flotation treatments.
  • Deinkingware grades D 31 and D 39
  • a Sorting of waste paper in which also a fraction mixed waste paper (Variety B 12) and a fraction Kaufhausaltpapier (variety B 19) may be incurred, won.
  • Well-known Deinkingware consists largely of uncrushed Newspapers and magazines and generally has at least 60% Newspapers as well as a total amount of contaminants, including sand, glass, staples Cardboard, cardboard, of about 3%.
  • An entrance control of Old paper deliveries of the variety Deinkingware can be used in addition to a conventional one Sample sorting and weighing of individual rejected components also according to the INGEDE method, in which a sample on a Observation surface is spread and individual components on the Observed area counted or estimated and with previously determined Weighting factors are multiplied.
  • DE-A-25 42 571 describes a method for sorting of waste paper, in which the waste paper was placed directly in a crusher and crushed the Waste paper by means of two wind sifts connected in series in three Fractions is split. This is provided, the shredded waste paper to loosen up in the first air classifier and a first heavy fraction, which cardboard, cardboard and heavy Kraft papers greatly enriched contains, split off. The remaining light fraction from the first Wind sifter is then fed to the second air classifier and into a second heavy fraction, which cardboard, cardboard and heavy Kraft strong enriched, as well as a light fraction containing illustrated magazines, Contains newspapers and other press papers heavily enriched, separated. The Speeds of wind sifting are high here. Since in the collected Waste paper heavy impurities, such.
