Abstract:
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).
Abstract:
A system for processing a heterogeneous material includes a conduit for a pressurized fluid and a nozzle assembly in fluid communication with the conduit. The nozzle assembly includes a plurality of adjustable nozzles configured such that fluid streams passing through each nozzle intersect at an oblique angle after passing through the nozzles. At least one of the fluid streams comprises a heterogeneous material. A method of processing a heterogeneous material includes entraining heterogeneous particles into at least one fluid stream, passing the fluid stream through an adjustable nozzle, impacting the fluid stream with another fluid stream at an oblique angle to ablate the heterogeneous particles, and classifying the heterogeneous particles.
Abstract:
A method for producing powder including supplying a powder material to a fluidized bed container, jetting fluid from each of a plurality of fluid jetting nozzles provided in the fluidized bed container to collide against each other, thereby fluidizing and pulverizing the powder material in the fluidized bed container to form powder, classifying the powder using a centrifugal classification rotor provided at the upper part of the fluidized bed container and discharging the classified powder from an outlet by being guided by the centrifugal classification rotor, wherein the centrifugal classification rotor is rotated at a first rotating speed for a predetermined time from the beginning of the flow of the powder material in the fluidized bed container, and at a second rotating speed after the predetermined time has passed, and the centrifugal classification rotor is controlled so that the first rotating speed is higher than the second rotating speed.
Abstract:
A plurality of pre-formed controlled particles for use in an aerosol deposition method by which an aerosol with brittle material fine particles dispersed in a gas is sprayed toward a substrate to form a structure made of the brittle material fine particles. Each of the controlled particles includes an assembly packed with a plurality of fine particles which are not chemically bonded together, which include the brittle material fine particles, and have a mean primary particle diameter of 0.1 μm or more and 5 μm or less. The controlled particles have a mean circle-equivalent diameter of 20 μm or more.
