Primary & Secondary DDC-Sizers McLanahan

Inward rotating rolls on primary and secondary sizers allow under-sized feed material to flow around the crushing zone and backside of the inward rotating rolls. The intermeshing sizing combs prevent any oversized material from passing through. This creates a screening effect and minimizes additional fines generation, which can be created through inter-particle crushing.
