•No power consumption. •Simplicity and great durability. •Possibility of installation in the basement (under the base), without external piping (piping are inside the housing mill, requiring available space). •Ensures oscilations always equal of pistons of the mill, compensating differences due to the drive (crownwheels) and uneven cane feeding. •Eliminates all the problems caused by different oscillation of bearings, such as flange bolt breaks, wear, break flanges, etc. •Protects the hydraulic cylinders of abrupt changes in pressure and risk of overload, because they are not connected to the top cap. •Improvement the whole operational system with excellent cost-benefit ratio •Gain efficiency in the milling process.
