Ringwalzenmühle. Patentiert im Deutschen Reiche vom 25. Dezember 1924 ab.Ring roller mill. Patented in the German Empire on December 25, 1924.
Gegenstand vorliegender Erfindung ist eine Verbesserung an Ringwalzenmühle^The present invention is an improvement on the ring roller mill ^
Bei den bekannten Ausführungsformen von Ring\valzenmühlen wird der in einem Gehäuse drehbar angeordnete Mahlring durch eine in diesem Mahlring exzentrisch angeordnete Mahlwalze angetrieben. Um das Mahlgut zwischen den beiden im gleichen Sinne umlaufenden Mahlflächen nicht nur zerquetschen, sondern auch zerreißen, also schroten zu können, konnte bei einer bekannten Bauart die Umfangsgeschwindigkeit des mitgenommenen Mahlringes gegenüber der Umfangsgeschwindigkeit der Mahlwalze durch eine Bremse verringert werden. Bei anderen Ringwalzenmühlen arbeiteten in einem Mahlring drei exzentrisch angeordnete Mahlwalzen, die durch Federdruck o. dgl. von innen gegen den Mahlring angepreßt wurden. Eine Mahlwalze wurde angetrieben, während die anderen Mahlwalzen durch den Mahlring in Umdrehung versetzt wurden. Die Mahlwalzenflächen erhielten eine ballige Form, woraus sich verschiedene Umfangsgeschwindigkeiten in den einzelnen Ouerschnitten der ^Mahlwalzen ergaben. Derartige Konstruktionen haben nicht die genügende Anpassungsfähigkeit an das zu mahlende Gut, um eine hohe Leistung und ein feines Ausmahlen in einem ununterbrochenen Arbeitsgange zu gewährleisten. In the known embodiments of ring mills, the is in a housing rotatably arranged grinding ring by an eccentrically arranged in this grinding ring Driven grinding roller. To circulate the grist between the two in the same sense Not only crushing grinding surfaces, but also tearing them, i.e. being able to grind, could with a known design the peripheral speed of the entrained grinding ring compared to the peripheral speed the grinding roller can be reduced by a brake. Other ring roller mills worked in a grinding ring three eccentrically arranged grinding rollers, which by spring pressure o. The like. From the inside were pressed against the grinding ring. A grinding roller was driven while the other grinding rollers were set in rotation by the grinding ring. The grinding roller surfaces were given a spherical shape, resulting in different peripheral speeds in the individual cross sections of the ^ Grinding rollers yielded. Such constructions do not have sufficient adaptability of the material to be ground in order to achieve high performance and fine grinding in to ensure uninterrupted work.
Nach vorliegender Erfindung wird der Mahl Vorgang auf die in einer Mehrzahl in einem Mahlringe vorhandenen einzelnen Mahlwalzen verteilt, wie es den Bedürfnissen tatsächlich entspricht. Es seien drei MahlwalzenAccording to the present invention, the grinding process is based on the plural in A grinding ring distributed individual grinding rollers as it actually needs is equivalent to. There are three grinding rollers
