Designed to improve yield at suitable passages in flour milling diagrams. Can be installed after roller mills or suspended at upper bends of pneumatic conveying pipes. It disperses adhering particles in fine and medium semolina and helps lower ash content. Two versions are described: round pins on the fixed upper disc with square pins on the lower rotating disc, or round tapered pins on both discs. All pins are heat-treated. Capacity and motor options vary by need.
