Indeed, according to Boulvin et al. [44], experimental data from a grinding circuit show that mill throughput impacts the separating curve. A recent experimental study on parameters affecting the VRM performance shows a correlation between product fineness and dynamic separator speed, mill throughput, and the rollers hydraulic pressure applied to the grinding table of the VRM [45].

The performance of hydraulic system plays an important role in roller mill. The hydraulic system was regarded as a vibration system with a single degreeoffreedom and the differential equation of roller was derived on the basis of the analysis of piston movement. It was found that the dynamic performance is affected by the damping ration, which depends on the performance of the hydraulic oil ...

The hydraulic system is also smart and compact; one hydraulic unit serves for the four roller units. 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 ...

The mill foundation is designed according to the force transmission, which results in a vibration value due to the grinding process of less than 2mm/s, measured at the roller units. Of course, to absorb the grinding forces and load spectrum, and to ensure the damping behaviour, reinforcement and post tensioning are needed.
