Dosing roller, dosing devices and dosing method for bulk material particles

摘要

The roller (10) has dosing chambers (1) arranged at an outer surface of the roller and conveying bulk material particles during a dosing process. The dosing chambers comprise a chamber surface lying back in a rotation direction (U) of the roller. The chamber surface is designed as a curved guide surface for the bulk material particles and exhibits a ramp. The dosing chambers are interconnected by a connection passage. The chamber surface of the dosing chambers exhibits an angle smaller than 90 degree to an outer side of the roller. An independent claim is also included for a method for dosing bulk material particle.
