Abstract
A roller mill system includes a vessel having an inlet, an outlet, a grinding zone and a classifier zone. The grinding zone includes a grinding assembly configured for grinding the material into fine particles. The grinding zone also includes a rejects capture and discharge system that includes one or more discharge conduits for conveying rejects away from the vessel. The rejects capture and discharge system includes: 1) a collection trough located under the grinding assembly and in communication with one of the discharge conduits, for discharging rejects from the grinding zone; and/or 2) a turbine classifier mounted in the classifier zone. The turbine classifier is rotatable about a central axis. Another outlet is formed in a side wall of the classifier zone. The turbine classifier is configured to expel the rejects radially outward therefrom, through the side wall outlet and into another one of the discharge conduits.
