Grinds wheat from the cleaning section into flour, with pneumatic control. The sheet-steel frame is machined to ensure roller parallelism. Rubber strips under the bearing slides absorb vibration. Roller specifications depend on the milling diagram and desired flour yield. Air-operated valves control the machine; incoming product activates the pistons and feeding rolls. A plate regulates feed quantity and distributes the product as a curtain between the rollers. Brushes beneath the rollers prevent product buildup. When feed stops, the valves separate the rolls and stop feeding. Helical gears transmit power with low noise and vibration. Front levers allow precise parallelism adjustment. Current is displayed on the panel ammeter, and a transparent inlet allows observation of product flow.
