Abstract

A crushing plant comprising a crushing rotor (12), a crushing plate (13) as well as an endless conveyor belt (6) supplying the material to be crushed and sweeping the crushing plate (13), has a particularly simple structure, the endless conveyor (6) forming at least one transport run (5) and in the area of the crushing plate (13), an inclined transport run. The endless conveyor (6) is thereby configured as a closed plate conveyor. The operation of the crushing plant is such that the endless conveyor (6) stops temporarily in case of exceeding a predetermined crushing pressure.

Description

Die Erfindung bezieht sich auf einen einen Brechrotor, eine Brechplatte und einen das Brechgut zuführenden, die Brechplatte überstreichenden Endlosförderer aufweisende Brechanlage (vgl- z.B. FR-A- 2 374 958, Fig. 6).The invention relates to a crushing rotor, a crushing plate and a crushing plant which feeds the crushed material and passes over the crushing plate (cf. e.g. FR-A-2 374 958, Fig. 6).

Brechanlagen dieser Art, die auch als Durchlaufbrecher bezeichnet werden, weisen in der Regel einer ansteigend angeordneten Bandförderer auf (FR-A-2 374 958), oder einen horizontal angeordneten Endlosförderer auf, der gleichzeitig die Brechplatte überstreicht. Der Endlosförderer ist dabei als Ketten- bzw. Stegkettenförderer ausgebildet. Diese bekannten Brechanlagen, die oftmals mit einem schlechten Wirkungsgrad arbeiten, sind nur speziell und begrenzt einsetzbar.Crushing plants of this type, which are also referred to as continuous crushers, generally have an ascending belt conveyor (FR-A-2 374 958) or a horizontally arranged endless conveyor which simultaneously sweeps over the crushing plate. The endless conveyor is designed as a chain or web chain conveyor. These known crushing plants, which often work with poor efficiency, can only be used in a special and limited way.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Brechanlage zu schaffen, die bei einfachem Aufbau vielseitig einsetzbar ist. Diese Aufgabe ist gelöst mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1. Die Erfindung bringt den Vorteil, daß durch eine Zusammenfassung verschiedener Teile, nämlich der Zuförder- und Aufgabevorrichtung mit dem Brechrotor Herstellungs- und Unterhaltungskosten in erheblichem Umfang eingespart werden können.The invention is based on the object to provide a crushing plant which is versatile in use with a simple structure. This object is achieved with the features of the characterizing part of claim 1. The invention has the advantage that manufacturing and maintenance costs can be saved to a considerable extent by combining different parts, namely the feeding and feeding device with the crushing rotor.

Außer den bekannten Durchlaufbrechern sind auch bereits Einwalzenbrecher mit einer sogenannten umlaufenden Brechwand bekannt geworden. Diese Brecher weisen ebenfalls im Bereich der Walze eine abfallende Förderstrecke auf, sie unterscheiden sich jedoch hinsichtlich der übrigen Merkmale sowie in der Aufgabenstellung wesentlich von der Erfindung.In addition to the known continuous crushers, single-roll crushers with a so-called rotating crushing wall have also become known. These crushers also have a sloping conveyor section in the area of the roller, but they differ significantly from the invention in terms of the other features and the task.

Ein Durchlaufbrecher, der bereits eine ansteigende Zuförderstrecke seines endlosen Kettenförderers aufweist, ist aus der GB-A-2 079 624 vorbekannt. Dieser Brecher ist jedoch nicht mit einer Brechplatte, sondern mit einer dem Brechrotor gegenüberliegenden Brechwalze versehen, die im unteren Bereich des Brechrotors angeordnet ist und gleichzeitig als Umlenkrolle für das Kettenband dient. Von diesen Merkmalen macht die vorliegende Erfindung keinen Gebrauch.A continuous crusher which already has an increasing feed section of its endless chain conveyor is known from GB-A-2 079 624. However, this crusher is not provided with a crushing plate, but with a crushing roller opposite the crushing rotor, which is arranged in the lower region of the crushing rotor and at the same time serves as a deflection roller for the chain belt. The present invention makes no use of these features.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen wiedergegeben.Advantageous embodiments of the invention are given in the subclaims.

Besonders vorteilhaft ist es, wenn der Endlosförderer ein Plattenbandförderer oder dergleichen ist, da auf diese Weise Funktionssicherheit und geringer Verschleiß der Anlage gewährleistet werden kann.It is particularly advantageous if the endless conveyor is a slat conveyor or the like, since in this way functional reliability and low wear of the system can be guaranteed.

Insbesondere für fahrbare Brechanlagen kann die Zuförderstrecke mit Vorteil auch als Steilförderstrecke ausgebildet werden, wodurch eine weitere Verringerung der Abmessungen der Anlage erzielt wird. Die Zuförderstrecke wie auch der abfallende Teil der Förderstrecke kann erforderlichenfalls zur Anpassung an verschiedene Betriebszustände verstellbar sein.In particular for mobile crushing plants, the feed conveyor line can also advantageously be designed as a steep conveyor line, whereby a further reduction in the dimensions of the system is achieved. The feed section as well as the falling part of the conveyor section can be adjustable if necessary to adapt to different operating conditions.

Die Erfindung betrifft auch ein Verfahren zum Betrieb der Brechanlage, das darin besteht, daß der Endlosförderer bei Überschreitung eines bestimmten vorgegebenen Brechdrucks kurzzeitig angehalten wird. Dieses Verfahren bringt den Vorteil, daß während des Anhaltens eine größere Brechkraft wirksam werden kann. Besonders vorteilhaft ist es, wenn das Anhalten durch eine Antriebsmotor-Leistungs-Regelung gesteuert wird.The invention also relates to a method for operating the crushing plant, which consists in that the endless conveyor is briefly stopped when a certain predetermined crushing pressure is exceeded. This method has the advantage that a larger refractive power can be effective during stopping. It is particularly advantageous if the stopping is controlled by a drive motor power control.

In der nachfolgend näher erläuterten Zeichnung sind zwei Ausführungsbeispiele der Erfindung schematisch dargestellt. Es zeigen:

  • Fig. 1 eine Brechanlage in senkrechtem Schnitt und
  • Fig. 2 einen Teil einer solchen Anlage im Brechbereich ebenfalls im senkrechten Schnitt im großeren Maßstab.
Two exemplary embodiments of the invention are shown schematically in the drawing explained in more detail below. Show it:
  • Fig. 1 is a crushing plant in a vertical section and
  • Fig. 2 shows a part of such a plant in the crushing area also in vertical section on a larger scale.

Wie aus Fig. 1 ersichtlich, weist die Brechanlage ein Gehäuse 1 auf, das im Aufgabebereich einen Aufgabebunker 2 und im Brechbereich die Seitenwände 3 sowie die Stirnwand 4 eines Brecherteils bildet. Unter dem Aufgabebunker 2 ist die Zuförderstrecke 5 eines Endlosförderers 6 angeordnet, der mit einem abfallenden Teil 7 im Bereich der Seitenwände 3 über zwei Umlenkrollen 8 und 9 geführt ist. Unter dem Obertrum der Zuförderstrecke sind Stützrollen 10 und unter dem gemeinsamen Untertrum des Endlosförderers 6 sind im Umlenkbereich unter der oberen Umlenkrolle 8 Stützrollen 11 angeordnet. Zwischen den Seitenwänden 3 ist ein mit Hämmern versehener Brechrotor 12 angeordnet, der einer sich zwischen den Umlenkrollen 8 und 9 erstreckenden Brechplatte 13 gegenüberliegt. Der Brechrotor 12 ist horizontal verschiebbar gelagert, um verschiedene Brechspalte einstellen zu können.As can be seen from FIG. 1, the crushing plant has a housing 1 which forms a feed hopper 2 in the feed area and the side walls 3 and the end wall 4 of a breaker part in the crushing area. Under the feed hopper 2, the feed section 5 of an endless conveyor 6 is arranged, which is guided with a falling part 7 in the region of the side walls 3 over two deflection rollers 8 and 9. Support rollers 10 are arranged under the upper run of the feed section and 8 support rollers 11 are arranged in the deflection area under the upper deflection roller under the common lower run of the endless conveyor 6. Arranged between the side walls 3 is a crushing rotor 12 provided with hammers, which is opposite a crushing plate 13 extending between the deflecting rollers 8 and 9. The crushing rotor 12 is horizontally displaceable in order to be able to set different crushing gaps.

Das Brechgut wird im Bereich des Aufgabebunkers 2 auf die Zuförderstrecke 5 des Endlosförderers 6 aufgegeben und bewegt sich in Richtung der Pfeile über die Umlenk: rolle S hinweg um danach in den zwischen dem Brechrotor 12 und der Brechplatte 13 ausgebildeten Brechspalt 14 zu fallen. In zerkleinerter Form wird das Brechgut dann über eine Schurre 15 einem abfördernden Bandförderer 16 aufgegeben.The crushed material is fed in the area of the feed hopper 2 onto the feed section 5 of the endless conveyor 6 and moves in the direction of the arrows over the deflection: roll S to then fall into the crushing gap 14 formed between the crushing rotor 12 and the crushing plate 13. In crushed form, the crushed material is then fed to a conveyor belt conveyor 16 via a chute 15.

Der Endlosförderer 6 weist ein geschlossenes, aus geeignetem verschleißfestem Material bestehendes Band auf. Als Brechgut kommen alle für einen Hammerbrecher geeigneten weichen bis mittelharten Stoffe in Betracht. Um Verunreinigungen, wie sie insbesondere bei schmierenden Stoffen, insbesondere bei bestimmten Kohlesorten, auftreten,zu beseitigen, ist am Umfang der Umlenkrolle 9 und des Brechrotors 12 jeweils im unteren Bereich ein nachstellbarer Abstreifer 17 und 18 angeordnet.The endless conveyor 6 has a closed belt consisting of a suitable wear-resistant material. All soft to medium-hard materials suitable for a hammer crusher can be considered as crushed material. In order to remove contaminants, such as those that occur in particular with lubricating substances, in particular with certain types of coal, an adjustable scraper 17 and 18 is arranged in the lower region on the circumference of the deflecting roller 9 and the crushing rotor 12.

Der Aufbau der Brechanlage nach Fig. 2 ist der gleiche wie im vorhergehenden Ausführungsbeispiel. Anstelle eines Hammerbrecher-Rotors ist jedoch als Rotor eine mit Zähnen 19 versehene Brechwalze 20 eingesetzt. Die Brechwalze 20 ist ebenfalls horizontal verschiebbar angeordnet und wird dabei durch einen an ihren Lagern 21 jeweils angreifenden hydraulischen Hubzylinder 22 verstellt. Als Endlosförderer 6' ist bei dieser Brechanlage ein aus Stahlplatten bestehendes Plattenband verwendet, das zu beiden Seiten mit Zähnen versehen ist, die in entsprechende Zähne von Antriebsrädern 27 eingreifen, wie es durch Strichpunktlinien 23 angedeutet ist. Die Brechplatte 13' ist auf einer Unterkonstruktion 24 befestigt, welche die Lager 25 und 26 der Umlenkrollen 8' und 9' verbindet und damit ein besonders steifes Gerüst für den Endlosförderer 6' bildet. Die Umlenkrollen 8' und 9' sind jeweils mit einem Hydromotor als Antriebseinheit versehen, dessen Geschwindigkeit bis zum Stillstand stufenlos verstellt werden kann. Eine Antriebsmotor-Leistungs-Regetung sorgt dafür, daß bei Überschreitung eines bestimmten vorgegebenen Brechdrucks, wie er bei Übergröße oder Überhärte des Brechtguts auftreten kann, der Endlosförderer kurzzeitig angehalten wird. Hierdurch wird für diesen Zeitraum eine feste Brechbacke gebildet. Nachdem der Brechdruck wieder unter einen bestimmten Wert abgesunken ist, wird die ursprüngliche Geschwindigkeit des Endlosförderers wieder eingestellt. Diese Ausführung ermöglicht es, daß härteres Material gebrochen werden kann, als diese normalerweise mit nur einer Brechwalze möglich ist. Durch Veränderung des Brechspalts kann der Feinanteil des ausgetragenen Brechguts verändert bzw. reguliert werden. Weitere Reguliermöglichkeiten, insbesondere in bezug auf die Brechleistung können im Bedarfsfall dadurch erzielt werden, daß der Winkel der abfallenden Förderstrecke in bezug auf die Senkrechte veränderbar ist.The structure of the crushing plant according to Fig. 2 is the same as in the previous embodiment. Instead of a hammer crusher rotor, however, a crushing roller 20 provided with teeth 19 is used as the rotor. The crushing roller 20 is also arranged to be horizontally displaceable and is supported by one on each of its bearings 21 attacking hydraulic lifting cylinder 22 adjusted. As an endless conveyor 6 ', a plate belt consisting of steel plates is used in this crushing plant, which is provided on both sides with teeth which engage in corresponding teeth of drive wheels 27, as indicated by chain lines 23. The crushing plate 13 'is fastened to a substructure 24 which connects the bearings 25 and 26 of the deflecting rollers 8' and 9 'and thus forms a particularly stiff frame for the endless conveyor 6'. The deflection rollers 8 'and 9' are each provided with a hydraulic motor as a drive unit, the speed of which can be infinitely varied until it comes to a standstill. A drive motor power control ensures that the continuous conveyor is briefly stopped when a certain predetermined crushing pressure is exceeded, as can occur when the crushed material is too large or too hard. As a result, a fixed jaw is formed for this period. After the crushing pressure has dropped below a certain value, the original speed of the endless conveyor is set again. This design enables harder material to be broken than is normally possible with only one breaker roller. By changing the crushing gap, the fine fraction of the discharged material can be changed or regulated. If necessary, further regulating options, in particular with regard to the breaking power, can be achieved in that the angle of the sloping conveyor path can be changed with respect to the vertical.

Zur Verminderung der Antriebskraft sowie auch zur Verschleißminderung ist zwischen dem Endlosförderer. und der Brechplatte 13 bzw. 13' eine Schmierung vorgesehen ist, deren Speisung selbsttätig erfolgt. Die Konstruktion der Brechanlage ermöglicht es ferner, verschliessene Teile leicht.auszuwechseln.To reduce the driving force as well as to reduce wear is between the endless conveyor. and the crushing plate 13 or 13 'is provided with lubrication, which is fed automatically. The design of the crushing plant also makes it easy to replace closed parts.

Die Zuförderstrecke 5 ist in den meisten Fällen, insbesondere wenn der Erfindungsgegenstand wie bevorzugt, als fahrbare Brechanlage gestaltet ist, ansteigend ausgebildet. Der Bunker 2 kann dann auf einfache Weise ohne Zwischenschaltung eines Förderbandes durch Kipplastwagen, Frontlader, Löffelbagger oder ähnliche Transporteinheiten erfolgen. Bei dieser Art der Beladung kann der Abzug des Brechguts aus dem Bunker durch Änderung der Geschwindigkeit des Endlosförderers vergleichmäßigt werden. Wenn die neue Brechanlage für einen besonders vielseitigen Einsatz in Betracht kommt, so kann die Zuförderstrecke ebenfalls winkelverstellbar - bis hin zur Waagerechtenausgebildet sein und ggf. auch eine oder mehrere Stufen aufweisen.In most cases, the feed conveyor 5 is designed to rise, in particular if the subject of the invention, as preferred, is designed as a mobile crushing plant. The bunker 2 can then be carried out in a simple manner without the interposition of a conveyor belt by dump trucks, front loaders, backhoe excavators or similar transport units. With this type of loading, the removal of the crushed material from the bunker can be evened out by changing the speed of the endless conveyor. If the new crushing plant is considered for a particularly versatile use, the feed path can also be adjustable in angle - designed to be horizontal and possibly also have one or more stages.

Bei der Ausbildung als fahrbare Brechanlage kann das Fahrwerk bevorzugt demontierbar oder als selbstfahrende, die Anlage anhebende Transporteinheit, die auch noch andere Geräte versetzen kann (sog. semimobile Anlage), ausgebildet sein.When designed as a mobile crushing plant, the undercarriage can preferably be dismantled or designed as a self-propelled transport unit which raises the plant and can also move other devices (so-called semi-mobile plant).
