Areas of Application   Preparation of soil samples for chemical and physical analysis, e.g. determination of the contents for yield optimisation and pollutant identification. Comminution of agglomerates to a grain size of 2 mm, e.g. according to the requirements of the Sewage Sludge Regulation or DIN 19683.     Method of Operation   Agglomerated soil samples are broken up through the combination of collision forces and friction.
