Abstract (en)

[origin: WO0178898A1] A description is provided of a roller press comprising two oppositely rotating rollers (1, 2) which are driven by means of a drive system. The roller press is peculiar in that the drive system is designed so that its lowest natural torsional frequency Vsystem is greater than a calculated frequency expressed by formula (I) where V represents roller velocity, D roller diameter, H grinding bed thickness, ρout density of pressed cakes, ρin bulk weight of feed to roller press. This will allow the roller press to be designed for operation at roller peripheral velocities in excess of 1.5 m/s.
