Abstract:
Device (1) for the micronization of substances comprising two rotors (3) driven in a direction (ω) opposite to each other, each rotor (3) carrying at least one row of multiple hitting elements (5, 7) forming a ring (9, 11), said rings (9, 11) being arranged concentrically in, the rings (9, 11) of the different rotors (3) engaging alternately with one another, the hitting elements (5, 7) being suitably arranged to provide transportation of the substance from inside the rings (3) to the outside by effecting a suitable airflow, at least two, directly adjoining rings (9, 11) carrying hitting elements (5, 7) with different foot print wherein at least a first ring (9) is equipped with trapezoidal hitting elements (5) with trapezoidal foot print and at least one other ring (11), directly adjoining the first ring (9) is equipped with triangular hitting elements (7) with triangular foot print.
Abstract:
A method and apparatus for treating materials or material mixtures in a treatment apparatus operating on the principle of the double-action impact mill, which comprises a discharge conveyor (34), such as a discharge screw. A material layer (40) is maintained between the discharge opening and the discharge conveyor, using the material exiting the outermost ring (16') of the treatment apparatus through the discharge opening (30), which layer prevents free discharge of the material to be treated from the treatment apparatus.
Abstract:
A part of an outer wall composing a clean box 2 becomes a component of a particle processing apparatus, a processing chamber 31 and the clean box 2 are integrated, the entire apparatus can be made compact, and in accordance with such compactness, even when a shaft sealing means 6 and an oil sealing means 323 are 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 unit 7 and use involving no necessity of a raw material supply unit 7 can 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 unit 7 itself.

Abstract:
A first rotor disk (21) and a second rotor disk (22) having a plurality of crushing pins (30) mounted so as to form rows along the circumference are opposed to each other and rotatably supported within casings (14, 15). The first and second rotor disks (21, 22) are rotated to crush materials to be crushed which are charged into the casings (14, 15). The crushing pins (30) are mounted on the first and second rotor disks (21, 22) in a cantilever manner. Escape spaces (21a, 21b, 22a) are provided on the first and second rotor rotor disks (21, 22) so as to face to the extreme ends of the crushing pins (30).
Abstract:
A method and apparatus for individually collecting layers from a laminated film containing many layers made of different materials by peeling or separating the layers one from the other. The laminated film having a plurality of layers made of different materials is shredded (120) into a plurality of fragments to be processed (82); and the fragments to be processed are peeled or separated (130) according to the type of layer by applying an impact frictional striking force to each of the fragments to be processed (82). Subsequently, the peeled or separated layers obtained (83a,83b) in the peeling and separating step (130) are subjected to a wind force classifying step (30). The collected layers in the mixed state are separated from one another, and they are individually collected.
