AGGREGATE AND METHOD OF THERMAL PUNCH PROCESSING OF GRANULAR MATERIALS Russian patent published in 2009 - IPC B01J8/10 B01J19/18 B04B5/12 

FIELD: technological processes.

SUBSTANCE: invention concerns chemical industry and can be applied in cases where thermal processing of granular materials is required in manufacturing of catalysts, carriers, adsorbents, drying agents, in a drying and cooling process in chemical, food and woodwork industries. Aggregate includes vessel for source material, heaters, vertical shaft with rotation drive and poppet mounted on it. Source material flow controller is made in the form of bushing interacting with shut-off cone and mounted in the bottom part of source material vessel. Material flow controller has a drive for axial shift of the cone. At that bushing remains at its place, and flow controller drive has reverse temperature correlation with automatic programmed control system. Method involves material loading, distribution and transportation due to centrifugal forces at the heated rotating poppet surface. Poppet temperature is maintained by calibration clearance area adjustment at full heater output.

EFFECT: enhanced aggregate efficiency.
