摘要： A device and method for preparing a nano-fragmented product. A polysaccharide slurry is circulated in a polysaccharide supply path (3) via a chamber (2). Specifically, using a pump (8), the polysaccharide slurry in a tank (7) is circulated in a circulation path (9) which is formed using a vinyl hose, a rubber hose or the like. On the other hand, another slurry than the polysaccharide slurry is circulated through a second fluid medium supply path (4) as another circulation path via the chamber (2). Specifically, using a pump (11), the slurry other than the polysaccharide slurry in a tank (10) is caused to pass through a heat exchanger (12) and a plunger (13) and thereby circulate in the other circulation path. The slurry other than the polysaccharide slurry circulated in the second fluid medium supply path (4) is orifice-injected against the polysaccharide slurry circulated in the polysaccharide slurry supply path (3) and flowing through the chamber (2).

A method for producing powder product includes the steps of: Providing a supply of a precursor powder material; accelerating particles of the precursor powder material by combining them with a flow of gas; confining the accelerated particles in a milling chamber so that they collide with one another to effect a size reduction; and coating newly exposed surfaces of size-reduced particles with oil.

摘要： A method and a device for producing and/or conditioning powdered material. The aim of the invention is to provide a method and an associated device which are used for producing and/or conditioning powdered material in a spouted bed comprising inert particles and in which a dry, fine powder having a very small particle diameter is produced at a low cost and at adequately large quantities in a continuous operation. This aim is achieved by a method in which the material is treated in several stages in a spouted bed comprising inert particles. In the method, the powdered material that is preprocessed in a first spouted bed and is separated from the larger material particles in an integrated dust collector is fed to a superimposed second spouted bed as a material-gas flow along with the gas flow discharged from the first spouted bed in order to be further reduced in size and be conditioned. After separating the fine particles from the larger material particles in a dust collector that is integrated into the second stage, the fine particles are discharged from the two-stage spouted bed treatment along with the gas flow as a powdered material having very small particle diameters. The separated larger material particles are once again fed to the second spouted bed of the second jet chamber. The device includes a spouted bed apparatus in which a jet chamber encompassing an integrated dust collector as well as a second superimposed jet chamber encompassing another integrated dust collector are disposed.

摘要： A jet mill includes plural nozzle devices for discharging a composite stream of high velocity fluid. Each nozzle device includes a plural odd number of nozzle openings for discharging an individual stream of high velocity fluid. Each nozzle opening comprises (i) a converging region for converging and accelerating a volume of high pressure fluid; (ii) a throat region defining a narrowest diameter region of the nozzle opening; (iii) a first expansion region for producing a linear expansion of the volume of high pressure fluid, and (iv) a second expansion region for producing a turning expansion as well as a parallel flow of the volume of high pressure fluid. The first expansion region has a radius “r1” and a length “s1” with radius r1 and length s1 determined such that (dr1/ds1) is a constant. The second expansion region has a radius “r2” and a length “s2” with radius r2 and length s2 determined such that (dr2/ds2) is non-linear and a function of s2.

摘要： The present invention pertains to a fluidized-bed jet mill intended to overcome the problem whereby a fluid jet introduced into the fluidized bed at high velocity takes up solid particles from the fluidized bed mainly in the area of the jet near the circumference. To have solid particles in the core area of the fluid jet as well auxiliary jets with fluidized solid particles are caused to penetrate into the fluid jet to be introduced into the fluidized bed such that the solid particles reach the core area of the fluid jet to enrich the core area with solid particles and allow an area near the circumference to receive solid particles from the fluidized bed.
