The investigation results of the physical, chemical and strength properties dusts from bentonite sands treatment plants as well reclamation processes analogous spent sands, are presented in paper. aim investigations was determination preliminary conditions allowing to pelletising bowl granulator. verified examination methods were applied for testing such dust features as: specific density, bulk density loosely built compacted materials related them porosity, ignition losses reaction (pH). grain composition after measured by means laser diffraction analysis, significantly widening size measuring range. optimal wetting liquid content (in this case: water), at which water-dust mixture has best (formula) established. Examinations moisture influence on permeability, compactibility, flowability friability samples standard moulder's rammer also performed.
