Abstract:
A comminution reactor includes an inlet chamber, one or more processing chambers, and a discharge chamber. Each chamber includes a rotor, and the chambers are separated by split divider plates. The reactor is designed with assemblies comprising portions of the reactor walls and divider plates which rotate open to allow access to the inside of the reactor, including the shaft and attached rotors. The design of the rotors and vortex generators on the reactor walls direct the flow, optimize comminution, and minimize wear on the apparatus.
Abstract:
Eine Zerkleinerungsvorrichtung (10) umfasst einen in einem stationären Gehäuse (18) drehbar angeordneten Rotor (20), auf dem eine Mehrzahl von Zerkleinerungselementen (34) befestigt ist, die in einem vorbestimmten Abstand (D) von einer Umfangswandung (16) des stationären Gehäuses (18) angeordnet sind. Ferner ist zwischen dem äusseren Umfangsrand (32d) des Rotors (20) und der Umfangswandung (16) des Gehäuses (18) ein Austrittsspalt (46) für zerkleinertes Gut (48) vorgesehen. Erfindungsgemäss ist der Abstand (d) des äusseren Umfangsrands (32d) des Rotors (20) kleiner als der vorbestimmte Abstand (D) der Zerkleinerungselemente (34) von der Umfangswandung (16) des Gehäuses (18).

Abstract:
The device according to the invention relates to a rotor that can be rotated in at least one direction of rotation about a vertical axis of rotation, which rotor is provided with at least one guide member and at least one impact member, the take-off location of which guide member is displaced, when wear occurs along the guide surface, in such a way that the material is directed from a said displaced take-off location into a spiral path that is oriented essentially transversely or remains oriented essentially transversely to the impact surface of the impact member that is associated with the guide member.
Abstract:
The method and the device according to the invention relate to a rotor which rotates about a vertical axis and is fitted in a streamlined mill in which the stationary collision surface is constructed as smooth (cylindrical) collision ring and is arranged an adequate distance away from the rotor and thus makes it possible to allow the material to collide, optionally several times, in an essentially completely determine manner, or at an essentially predetermined collision location, at an essentially predetermined collision velocity and at an essentially predetermined collision angle; by which means a high probability of breakage and thus the degree of comminution is achieved, the energy consumption is reduced, wear is restricted and a crushed product is produced which has a regular grain size distribution, a restricted amount of undersize and oversize and a very good cubic grain configuration, the effect i.e. the determinism essentially not being influenced by the wear on the collision element, whilst the material does not rebound (or at least rebounds to a much lesser extent) against the rotor.
Abstract:
A method and an apparatus for finely crushing particles of material in a centrifugal mill or the like, wherein at least one rotor (13) projects the particles against stationary impact surfaces (20) in the mill, the comminution taking place substantially in vacuum. To obtain fractions with very small grains (below 10 mu ) with a low energy consumption the particles are accelerated in vacuum to such a high impact energy against the impact surface(s) (14) of the rotor (13), that a first crushing will take place before the particles are projected against the stationary impact surfaces (20) of the mill.
Abstract:
The invention is referred to agriculture, beekeeping branch and definitely can be applied in production of bee bread threshing machines. For the purpose of creation of safe and non-complex bee bread threshing machine, allow to increase the output and improve in quality of bee bread granules, the disk-type bee bread threshing machine consists of a body (1) with raw material loading (2) and escape (3) holes, electric motor (4) installed inside, disk form crusher (6) fastened to the vertical shaft (5) equipped with two or more vanes (7), formed of the same disk material and directed to the loading hole (2) side. If required there can be two and more vanes (7). The vanes are tilted at 0-30 degree angle from perpendicular position to the disk opposite to the rotation direction and sharp edges are rolled.˙
Abstract:
The invention relates to a crusher housing (67) which is provided with a lid member (69) that is provided with an inner lid lining face (82) that is positioned as closely as practical possible to the open rotor (72) creating essentially a sandwich rotor with a rotating rotor table and a stationary roof with minimum free space between the top side of the sliding members (85) and the inner lid lining face (82), which configuration provides the crushing chamber with a number of unique features in that vortex building and turbulence in the crushing chamber are severely limited, such that the particles are focused for accurate and undisturbed impact; increasing the reduction ratio, providing constancy to the breakage process - resulting in less oversize and less undersize, better shaping and a high degree of selectivity - and reduces wear along the feed opening and along the inner lid lining in dramatic way, saves on energy, and limits dust formation.
