Abstract

A materials processing device comprises a chamber (101) having a first chamber region (101b) with a substantially circular inner wall (202) and being connected to materials feeding means (101a; 510), and a second chamber region (102) fluidly connected to and arranged below the first chamber region and having a downwardly extending frusto-conical shape and a bottom opening (1 16). A gas exhaust channel (1 10) is arranged concentrically with the chamber axis (c-c) and extending a distance into the chamber. The device comprises a plurality of more nozzles (501), each nozzle having an inlet (512), an internal bore and an exit opening (502a; 502b) in fluid communication with the first chamber region (101b), and a pulse generator (504, 503; 505, 507, 508) configured for imparting pressure pulses on a gas (F) flowing through the nozzle. In operating the device, pressure pulses are imparted on the gaseous flow (F) flowing through the nozzle and the resulting pulsed gaseous flow (E) is ejected tangentially into the first chamber region (101b) in order to generate a rotary array of vortices within t he chamber. Typically, the device and method are useful for e.g. drying, separating, pulverizing and particle coating.
