Clamping system of a roller mill with a modular hydraulic storage unit

摘要

In a tensioning system (118), in particular a hydropneumatic tensioning system, a roller mill (110) with at least two cylinder units (124), each designed to apply a grinding pressure and a counterpressure, each cylinder unit (126) having at least two pressure storage vessels (126c, 126b) , a grinding pressure (126c) and a back pressure storage container (126b), as well as a hydraulic unit arranged close to the respective cylinder unit (124), a solution is to be created which makes it possible to reduce the assembly effort as well as the space requirement and thus the installation costs and also optimize operations to reduce operating and maintenance costs. This is achieved in that the at least one grinding pressure (126c) and the at least one back pressure storage container (126b) can be exchanged together with the hydraulic unit, and are designed as a modular hydraulic storage unit (130).
