Grain flow regulator for roller mills
Achieve consistent grain distribution and safeguard your roller mills from wear and costly downtime with our advanced flow regulator, engineered to efficiently remove impurities and maintain production integrity.

Regulates and Cleans Grain Flow
The Protector Roll Feeder by Ottevanger Milling Engineers is designed to enhance your roller mill operations by ensuring an even distribution of grains and cereals while filtering out impurities. This equipment is crucial for cleaning and purifying raw materials, reducing the risk of wear and potential downtime of your roller mills. The integrated feeder roll ensures consistent flow, while an embedded permanent magnet captures magnetic particles. With a high-capacity stationary and vibrating screen, it handles up to 60 tons per hour, optimizing both process efficiency and machine protection. Ideal for applications in grain, cereal, and feed industries, it supports production lines of cornflakes, poultry feed pellets, and more. Featuring variable amplitude settings and frequency control, this system offers seamless automation and integration into existing setups, making it a reliable choice for continuous, high-speed operations. The heavy-duty steel construction and optional screen executions cater to various product types, ensuring durability and adaptability in diverse processing environments.
