A wheat milling machine operates with these rollers just millimeters apart, allowing very little room for anything to pass unhindered. The rollers operate at different speeds and spin in opposite directions, pulling anything that passes through them with great force. Bulk grains are fed into these rollers, which make quick work of them.
