Abstract (en)
[origin: WO2020234191A1] The invention relates to a vibrating disc milling device (10) for comminuting feed material, comprising: a milling housing (11); a milling system (13) which is arranged in the milling housing in an oscillating manner and which comprises a milling chamber (13.1) and at least one millstone movably arranged in the milling chamber; at least one eccentric shaft drive (14), which is mounted in the milling housing and generates the oscillating movement in the milling chamber, and at least two eccentric shafts (15); and at least one compensating mass unit (16) which is coupled to the eccentric shaft drive and is designed to compensate for an imbalance; wherein the compensating mass unit is coupled to the eccentric shaft drive such that a phase offset of more than 180°, in particular more than 185°, can be set between the eccentric maximum of the compensating mass unit and the eccentric maximum of the milling chamber, thus allowing vibrationally optimized operating conditions. The invention additionally relates to a method for vibrationally regulating a vibrating disc milling device and to the use of eccentric shafts (15) with a phase offset.
