INSTALLATION FOR DEHYDRATION OF FINE CLASSES OF ORE AND NONMETALLIC MATERIALS Russian patent published in 2016 - IPC B01D43/00 F26B5/16 F26B9/08 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be used for dehydration of fine classes of ore and nonmetallic materials, including solid fossil fuels (coal, peat, etc.) with particle size of 0-6 mm. Installation for dehydration of fine classes of ore and non-metallic materials comprises device for supply of wet material, device to supply sorbent, device for mixing of wet material with sorbent with internal rotor, device for separation of dry material from sorbent, device for recovery of sorbent. Inner rotor of device for mixing of wet material with sorbent is made in form of a shaft with fixed tools for mixing material with a sorbent and movement of mixture with formation of zones arranged in-series along the axis. In area of wet material feed and mixing tools are fixed on shaft in form of rods or knives arranged parallel to each other, in area of sorbent supply tools are fixed on shaft in form of rods or knives arranged along spiral. Sorbent mixing zone with material consists of two parts, in first of which tools are fixed on shaft in form of blades arranged along spiral, and in second part and in zone of unloading tools are fixed on shaft in form of two ribbon augers, one is with greater radius of turn, swirled to move mixture to discharge zone, and second is with smaller radius, swirled in opposite direction to move mixture by counter-flow. In area of counter flow tool in form of short ribbon auger is secured on shaft, swirled to direct mix towards unloading zone.

EFFECT: technical outcome is effective dehydration of material.
