Abstract. The article presents results of the rock complex dewatering by vibrating device of new design, which allows to use simultaneously three dehydration mechanisms - vibration, vacuum and electroosmosis. Effect of electroosmotic method on the capillary moisture and increase of rock dehydration efficiency were established experimentally. Effect of complex dewatering on the changes of final moisture content was studied depending on area of perforated surface of the device. The findings make it possible to determine effectiveness of electrokinetic method in the new dewatering device for capillary moisture.
Keywords: vibration, evacuation, electroosmosis, dehydration, complex method.
