  • Spiral jet mill apparatus for micronisation of a powdered material or a material containing particles in general, with a novel system for feeding and dispensing the powdered material to be micronised, and corresponding process for micronisation of a powdered product
    Patent number: 9427743
    Abstract: Apparatus (10) for the micronisation of a powdered material (P) containing particles, comprising: a container (11), containing a reserve of the powdered product (P) to be micronised; a high-energy gaseous spiral fluid-jet micronising mill (12) with which powdered product (P) is micronised; and a feed system (13) to feed powdered product (P) from container (11) to the spiral jet mill (12), wherein feed system (13) comprises a special microdispenser device (20, 21, 26, 27, 28, 29) that micrometrically dispenses and directly feeds the powdered material (P), in a dense state, to the spiral jet mill (12), and wherein said microdispenser device (20) comprises one or more dispensing sections (21) which are cyclically filled with material originating from container (11) and then emptied to feed the material to the spiral jet mill (12), opening and closing at high frequency a plurality of control valves (26, 27, 28 and 29) associated with the dispensing sections (21) of the microdispenser device (20).
