Title
(DE) SPANNSYSTEM EINER WÄLZMÜHLE MIT EINER MODULAREN HYDRAULIKSPEICHEREINHEIT

(FR) SYSTÈME DE SERRAGE D'UN BROYEUR À ROULEAUX COMPORTANT UNE UNITÉ D'ACCUMULATION HYDRAULIQUE MODULAIRE
Abstract
(DE)
Bei einem Spannsystem (118), insbesondere einem hydropneumatischen Spannsystem, einer Wälzmühle (110) mit mindestens zwei, jeweils zur Aufbringung eines Mahl- und eines Gegendrucks ausgebildeten Zylindereinheiten (124), wobei jeder Zylindereinheit (126) mindestens zwei Druckspeicherbehälter (126c, 126b), ein Mahldruck- (126c) und ein Gegendruckspeicherbehälter (126b), sowie eine zu der jeweiligen Zylindereinheit (124) ortsnah angeordnete Hydraulikeinheit zugeordnet ist, soll eine Lösung geschaffen werden, die es ermöglicht, den Montageaufwand sowie den Platzbedarf und damit die Installationskosten zu reduzieren und außerdem den Betrieb zur Reduzierung der Betriebs- und Wartungskosten zu optimieren. Dies wird dadurch erreicht, dass der mindestens eine Mahldruck- (126c) und der mindestens eine Gegendruckspeicherbehälter (126b) mit der Hydraulikeinheit gemeinsam austauschbar, als eine modulare Hydraulikspeichereinheit (130) ausgebildet sind.
(EN)
In a clamping system (118), in particular a hydropneumatic clamping system, of a roller mill (110) having at least two cylinder units (124) that are respectively intended to apply a grinding pressure and a counter-pressure, wherein each cylinder unit (124) is assigned at least two pressure accumulator vessels (126c, 126b), namely a grinding pressure accumulator vessel (126c) and a counter-pressure accumulator vessel (126b), and a hydraulic unit arranged in the vicinity of each particular cylinder unit (124), a solution is intended to be created that makes it possible to reduce the assembly effort and the space requirement and thus the installation costs and also to optimize operation so as to reduce the operating and maintenance costs. This is achieved in that the at least one grinding pressure accumulator vessel (126c) and the at least one counter-pressure accumulator vessel (126b) are configured to be exchangeable together with the hydraulic unit, as a modular hydraulic accumulator unit (130).
(FR)
L'invention concerne un système de serrage (118), notamment un système de serrage hydropneumatique, d'un broyeur à rouleaux (110) pourvu d'au moins deux unités à vérin (124) respectivement configurées pour appliquer une pression de broyage et une contre-pression. Au moins deux récipients d'accumulation de pression (126c, 126b), à savoir un récipient d'accumulation de pression de broyage (126c) et un récipient d'accumulation de contre-pression (126b), ainsi qu'une unité hydraulique disposée à proximité de l'unité à vérin (124) correspondante, sont associés à chaque unité à vérin (124). L'invention a pour objectif de réaliser une solution qui permet de réduire la complexité de montage ainsi que l'encombrement et, de ce fait, les coûts d'installation, et aussi d'optimiser le fonctionnement en vue de réduire les coûts d'exploitation et de maintenance. Cet objectif est réalisé en ce que ledit récipient d'accumulation de pression de broyage (126c) et ledit récipient d'accumulation de contre-pression (126b) sont réalisés sous la forme d'une unité d'accumulation hydraulique (130) modulaire et peuvent être remplacés conjointement avec l'unité hydraulique.
