Abstract (en)
[origin: WO2010105783A1] The invention relates to a hydraulic array for roller mills, having a spring unit (11) for each grinding roll, a gas/oil reservoir (16, 17) and hydraulic supply systems for changing the operation states of the spring units or grinding rolls. In order to ensure an almost constant crushing power and a uniform contact pressure of the grinding rolls and at the same time reduce the production and assembly costs and the risk of failure of the components of the hydraulic system and to improve the exchange of components or the entire system, each spring unit of a grinding roll is associated, in its proximity, with its proper hydraulic supply unit (20) as a compact hydraulic system and a reservoir station (22) so that the necessary connections can be realized by means of relatively short conduits (23) and high-pressure lines (24). Every hydraulic supply unit can be pre-assembled under dust-free ambient conditions and accommodated for example in a hydraulic cabinet (25) and only needs to be connected on site.
