Abstract
Description
Die Erfindung betrifft ein Schlagwerkzeug für eine Schlagmühle, insbesondere zur Vermahlung von körnigen Produkten, wie zum Beispiel Getreidekörner, Malz oder dergleichen.The The invention relates to an impact tool for a hammer mill, in particular for grinding granular products, such as for example, cereal grains, malt or the like.
Schlagmühlen bzw. Hammermühlen mit vertikalen oder horizontalen Rotordrehachsen sind in verschiedenen Ausführungen bekannt. Der Rotor und die Schlagwerkzeuge befinden sich im Innern eines Gehäuses und sind von einem Siebmantel umgeben. Zum Mahlen gelangt das Mahlgut in einen, die Schlagwerkzeuge aufnehmenden Mahlraum, in welchem beim Aufprallen des Mahlgutes auf die Schlagwerkzeuge eine Zerkleinerung des Mahlgutes erfolgt. Der beim Mahlen entstehende Feinanteil verlässt den Mahlraum durch das umgebende Sieb und gelangt zu einer Auslassöffnung des Gehäuses.coffee grinders or hammer mills with vertical or horizontal rotor axes of rotation are known in different versions. The rotor and The impact tools are located inside a housing and are surrounded by a screen coat. For grinding, the millbase arrives in a, the impact tools receiving grinding chamber, in which when crushing the ground material on the striking tools a crushing of the ground material. The fines produced during milling leave the grinding chamber through the surrounding sieve and reaches an outlet opening of the housing.

Bekannt sind auch Schlagwerkzeuge mit zur Längsachse abgewinkelten Schlagflächen, die eine energiesparende Vermahlung ermöglichen sollen.Known are also impact tools with angled to the longitudinal axis Impact surfaces that enable energy-saving grinding should.
Schlagwerkzeuge werden sowohl aufgrund ihres Verschleisszustandes als auch vorbeugend und vor Erreichung eines signifikanten Verschleisses zur Vermeidung von Ermüdungsbrüchen gewechselt.Striking Tools are both due to their state of wear as well as preventive and avoid significant wear before achieving it changed from fatigue fractures.
Der Erfindung liegt die Aufgabe zugrunde, Schlagwerkzeuge für eine Schlagmühle, insbesondere zur Vermahlung von körnigen Produkten zu entwickeln, die eine höhere Standzeit aufweisen und eine bessere Ausnutzung der verfügbaren Standzeit ermöglichen.Of the Invention is based on the object striking tools for a hammer mill, especially for grinding of granular To develop products that have a longer service life and make better use of available life.
Die Aufgabe ist mit den Merkmalen des Patentanspruchs 1 gelöst. Die Schlagwerkzeuge weisen einen gehärteten Arbeitsbereich und einen ungehärteten Aufnahmebereich auf. Der Aufnahmebereich ist somit zäher und neigt weniger zum abreissen.The The object is solved with the features of claim 1. The impact tools have a hardened working area and an unhardened recording area. The recording area is thus tougher and tends less to demolish.
Vorteilhafte Ausführungsformen sind in den Unteransprüchen offenbart. So sind die Arbeitsbereiche bevorzugt einsatzgehärtet, insbesondere mit variablem Härteverlauf. Die Schlagwerkzeuge sind bevorzugt gelasert, was eine Verringerung der Kerbbruchneigung im Bereich der Bohrung bewirkt.advantageous Embodiments are in the subclaims disclosed. Thus, the work areas are preferably case hardened, in particular with a variable hardness profile. The striking tools are preferably lasered, which is a reduction in Notch tendency effected in the bore.
Es hat sich gezeigt, dass mit der erfindungsgemässen Schlagwerkzeug gegenüber bekannten Schlagmühlen mit vertikal angeordnetem Rotor eine deutliche Erhöhung der Standzeit insbesondere bei der Vermahlung von Rohprodukten für die Brauwirtschaft erreichbar ist.It has been shown that with the inventive impact tool compared to known impact mills with vertical arranged rotor a significant increase in service life especially in the grinding of raw materials for the Brewing is achievable.
Die Erfindung wird nachfolgend in einem Ausführungsbeispiel an Hand einer Zeichnung näher beschrieben. In der Zeichnung zeigen dieThe Invention will be hereinafter in an embodiment described in detail with reference to a drawing. In the drawing show the
