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.
Abstract:
The invention relates to a crusher housing that is provided with an impact block member (4) that is composed of impact blocks (47) which stretches along the drum wall such that at least one essentially closed inner space is created between the impact block member and the drum wall, such that the closed inner space fills with particle material when the impact block starts to wear through, creating a partly worn through impact face (14) that is partly autogenous of own material, which is compacted by repetitive impact, such that the partly worn through impact face provides still significant impact intensity as well as temporary protection to the construction behind the impact block member, which impact block member (4) is supported with the aid of at least one support member (25) such that collapse into the crushing chamber of the upper part of the impact block and/or of the lower part of the impact block is hindered, when an impact block (47) wears through completely.
Abstract:
The method and the device according to the invention relates to a stator and an armoured ring which are combined to give a stationary annular collision member that is arranged around the rotor, as it were in the form of a stator that is provided all round along the inside, which faces the axis of rotation, with protruding collision surface reliefs, each of which is provided with at least one collision surface that is arranged transversely in the ejection stream that the material describes when it is propelled outwards from the rotor.
Abstract:
Bei einer Anlage für die Behandlung von metallhaltigen Verbundstoffen als Behandlungsgut mit einem einer Prallmühle (30, 50) vorgeschalteten Metallabscheider (22, 22 a , 28) -- sowie gegebenenfalls einem der Prallmühle (30, 509 folgenden Wirbelstromscheider (54) als Einrichtung zur Abscheidung von Behandlungsgut durch Verwirbelung -- ist zum Rückgewinnen von Eisen- und NE-Metallen aus der Schlacke einer Müllverbrennungsanlage eine Siebstation (20) sowohl mit ihrem Austrag (21) für Feinkorn als auch mit dem Austrage (26) für das Überkorn jeweils an einen Metallabscheider (22, 28) angeschlossen, und dessen Austrag (24, 29) für nicht magnetisches Haufwerk ist eine Prallmühle (50, 30) nachgeordnet. Zudem ist eine Trennschnitt bei der als Grobsieb (20) ausgebildeten Eingangssiebstation für ein Überkorn von etwa 45 mm bis etwa 100 mm vorgesehen. Der Eingangssiebstation (20) ist ein Vorsieb (12) für eine Körnung von mehr als etwa 100 mm vorgeordnet, und an den Austrag (29) für nicht magnetisches Haufwerk des Metallabscheiders (28) ist für das Überkorn eine vertikale Prallmühle (30) angeschlossen, in deren Austrage (31) sich ein Metallabscheider (22 a ) befindet.
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 mill includes a generally vertical, rotatable shaft having at least one set of cutter blades driven thereby and a fan assembly mounted on the shaft below the cutter blades in position to receive output therefrom. The fan assembly includes a fan disc secured to the shaft and rotatable therewith. A plurality of fan blades is secured to the fan disc in a generally radial orientation. A terminal portion of the mill includes a gradually, radially expanding outer wall configured in a volute form. The expanded outer wall decreases wear and increases efficiency of discharge and airflow through the mill.
Abstract:
A rotor of the open type, rotatable in one or both directions of rotation, provided with a composed accelerating member (5) that comprises a radially arranged multiple block sliding member (11) and at least one attachment member (13), which radially arranged multiple sliding block member is of at least two sliding block parts (29,30), arranged in a radial direction, each provided with a sliding face part (31,34), directed in the same direction of rotation, creating a radially arranged multiple sliding face; the radially arranged multiple block sliding member, simple, dividing the weight of the sliding block member over at least two sliding block parts, limiting handling weight, limiting the centrifugal force generated by the sliding block part, essentially, without affecting acceleration performance.
Abstract:
Die Erfindung bezieht sich auf Verfahren und eine Vorrichtung zum Zerkleinern von Teilen und/oder Gütern, die hochfeste Stoffe oder Stoffgemische enthalten. Die Aufgabe der Erfindung besteht darin eine Vorrichtung und ein Verfahren anzugeben, welche ein Zerkleinern von Teilen und/oder Gütern in zuverlässiger und wirtschaftlicher Weise erlaubt, auch wenn diese hochfeste Stoffe oder Stoffgemische enthalten, wie Metallkörper, Verbundmaterialien oder auch Gussteile. Die Vorrichtung umfasst dabei einen Prallreaktor (10), der einen ersten Prallraum (11) und einen zweiten Prallraum (21) aufweist, wobei der erste Prallraum (11) einen zylinderförmigen Körper (12) und einen rotierbar angeordneten Scheibenrotor (13) aufweist, auf dessen Oberseite eine Mehrzahl von Prallelementen (15) angeordnet sind. Dabei soll der Scheibenrotor (13) so angeordnet sein, dass zwischen dem Scheibenrotor (13) und einer Unterkante des zylinderförmigen Körpers (12) ein vertikaler Spalt (14) ausgebildet ist, durch den vorzerkleinertes Gut aus dem ersten Prallraum (11) in den zweiten Prallraum (21) hindurchtreten kann, wobei der zweite Prallraum (21) seitlich durch eine Vielzahl von flachen Wandelementen (22) begrenzt ist, die so angeordnet sind, dass sie ein Vieleck bilden; und dass ein flügelförmiger Rotor (23) innerhalb des zweiten Prallraums (21) zur weiteren Zerkleinerung rotierbar angeordnet ist.
