sampling of all kind of materials

  • development of instructions for sampling of bulk materials, waste and recyled products
  • number of samples, gross sample size (mass or volume), single sample size, allocation and geometrical arrangement of samples in a heap, bale or material flow
  • scrap wood, used and recycled
  • broken glass from pots and bottles
  • scrap wire, cable scrap
  • electronics scrap
  • limestone
  • used lightweight packaging
  • paper/cardboard and paperboard container
  • scrap rubber
  • seeds
  • porous substances

sampling preparation, sample splitting, measurement uncertainty of sample splitting

analytical service for bulk material and recycled material

the following work-up steps/test are offered: 

  • comminution
    • jaw crusher, grinder, impact mills, cutting mills
    • mills in laboratory for dry and wet comminution (jet mironizer, ball mills, vibration mills, attritors)
  • agglomeration
    • pelleting plate
    • moulding and sintering techniques
  • methods of classifying
    • sieving, sifting
  • methods of sorting
    • sorting by density (sink-float-separator, laboratory washer)
    • electrostatic seperator
    • magnetic seperator
    • flotation aggregates
  • mixing/homogenizing/sample splitting
    • different aggregates for mixture
    • different sample splitter (s.a. splitting cross, chequered plate, rotation splitter)
  • drying/liquid-solid-separation
    • dryer, filtering aggregates
