Abstract
A bowl mill for producing coarse ground particles has a substantially closed body, a bowl assembly, a plurality of grinding rolls, and a coarse particle transport enabling area. The substantially closed body has an interior area. The bowl assembly includes a rotatable grinding table mounted for rotation in a direction of rotation in the interior area. The grinding table has a grinding surface thereon. The plurality of grinding rolls are positioned proximate the grinding surface. The grinding rolls and the grinding surface define a grinding area therebetween. The coarse particle transport enabling area is located radially outward from the grinding area. The coarse particle transport enabling area is configured to allow the coarse particles to freely exit the grinding area and to mitigate the coarse particles from being circulated back into the grinding area.
