Spiral jet mill equipment for atomizing powder materials or materials containing general particles, including a new system for feeding and supplying powder materials to be atomized, and corresponding processes for atomizing powder products

摘要

A device (10) for atomizing a powder material (P) containing particles, the container (11) containing the prepared powder material (P) to be atomized, and the powder material (P) being fine particles A high energy gaseous spiral fluid jet micronization mill (12) to be converted, and a feeding system (13) for feeding the powder product (P) from the container (11) to the spiral jet mill (12), A special microdispenser device (20, 21, 26, 27, 28, 29) in which the feeding system (13) feeds and sends the dense powder material (P) to the spiral jet mill (12) micrometrically. ) And the microdispenser device (20) is periodically filled with material from the container (11) and then emptied to supply material to the spiral jet mill (12) A plurality of control valves (26, 27, 28, 29) having one or a plurality of supply parts (21) and combined with the supply part (21) of the microdispenser device (20) are frequently opened and closed. An apparatus that makes powder material containing particles fine.
