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
- methods of sorting
- sorting by density (sink-float-separator, laboratory washer)
- electrostatic seperator
