Abstract.

The article presents new methods for building sand segregation and dehydration by vibrating screens. Conditions for further intensification of these processes are defined. A new method of shock-vibrating screening is proposed, which allows to intensify sand disintegration and, thanks to this, to increase efficiency of the sand segregation and dehydration. Impact of specific feeding load on screening technological parameters was studied. The proposed new method of shock-vibrating screening is especially useful at processing minerals of wide spectrum of size when it is necessary to separate thin classes (usually, rejects) and to maximally dehydrate ready products (oversized fraction) . Findings can be used for designing mathematical models of process of mineral segregation and dehydration and new shock-vibrating screens.

Keywords:

vibrating screening, shock-vibrating mode, segregation, dehydration, building sands.
