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 shaftis rotatably supported within a horizontally long casing, that a plurality of heat exchangersare 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 exchangersare formed as substantially hollow disk-shaped heat exchangers each having a notched recessdirected to a center from a circumferential edge.

Heat exchanging device for powder, and method for manufacturing the same

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 casinga horizontally provided drive shafta plurality of circular platesfixedly supported with intervals at the drive shaftand statorsarranged so as to be opposed to plate facesat lower peripheral edges of the circular platesand each having inclined facesthat cause a gap between the plate facesof the circular platesto become narrower toward peripheral edges of the plate facesThe plate facesof the circular platesand the inclined facesof the statorsform gap portions A where particles are held, and particle crushing and sizing portions B are formed by the peripheral edges of the circular platesand narrowest gap portions between the peripheral edges of the circular platesand the inclined faces of the stators

Powder particle disintegrating and sizing apparatus

A part of an outer wall composing a clean boxbecomes a component of a particle processing apparatus, a processing chamberand the clean boxare integrated, the entire apparatus can be made compact, and in accordance with such compactness, even when a shaft sealing meansand an oil sealing meansare disposed in proximity to each other, reliable shaft sealing performance is secured, whereby a shaft sealing structure enabling processing of fine particles by high speed rotation is provided. Furthermore, integration of setting means for components accompanied with assembly and disassembly of the processing chamber is achieved, the entire assembling structure is simplified and the assembly work is made easier, whereby a particle processing apparatus the assembly and disassembly of which accompanied with cleaning work can be easily carried out in a short time without loss of productive efficiency. Moreover, use requiring a raw material supply unitand use involving no necessity of a raw material supply unitcan be selectively achieved in a balanced manner in accordance with a supply manner for production in view of attachment and detachment accompanied with cleaning work, and this reduces the work burden of attachment, detachment, and cleaning of the supply unititself.

Particle processing apparatus

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.
