  • Patent number: 8813833
    Abstract: To provide a heat exchanging device for powder, which is capable of suppressing as much as possible the compression force applied to an object to be processed and reducing the manufacturing man-hour (time), while ensuring the piston flowability of the object to be processed. In order to achieve this object, the present invention is a heat exchanging device for powder, which is configured such that a shaft 13 is rotatably supported within a horizontally long casing 1, that a plurality of heat exchangers 30 are disposed at predetermined intervals on the shaft, and that a heat exchanging medium is supplied into the heat exchangers via the shaft, wherein the heat exchangers 30 are formed as substantially hollow disk-shaped heat exchangers each having a notched recess 31 directed to a center from a circumferential edge.

  • Patent number: 7455252
    Abstract: It is an object of the present invention to provide a particle crushing and sizing apparatus having a sufficiently wide particle crushing and sizing range, capable of being scaled down in size, and having high processing throughput. To achieve the object, a particle crushing and sizing apparatus has, in a casing 1a, a horizontally provided drive shaft 2, a plurality of circular plates 10 fixedly supported with intervals at the drive shaft 2, and stators 5 arranged so as to be opposed to plate faces 10a at lower peripheral edges of the circular plates 10 and each having inclined faces 5b that cause a gap between the plate faces 10a of the circular plates 10 to become narrower toward peripheral edges of the plate faces 10a.

  • Patent number: 4915987
    Abstract: A method of improving the quality of the surface of solid particles is disclosed. The method includes fixing material different from the solid particles to the surface of the solid particles by the use of an impact striking device. The material fixed to the solid particles can be other solid particles or particles contained in a liquid, which forms a film.
