The grinding force for comminution is generated solely by one hydraulic cylinder per roller unit. This concept also requires only one piston accumulator to act as the spring system. The fixed bearing is maintenancefree, and although the roller bearing is located in the mill, it is fully capsuled without any shaft sealing inside the mill.
