Grain flow regulator for roller mills
Modern milling operations require precise and consistent grain flow to maximize mill efficiency and minimize downtime caused by wear or damage. This calls for a solution that not only ensures an even distribution of raw materials but also removes impurities effectively.

Regulate grain flow and protect roller mills
The Protector Roll by Ottevanger Milling Engineers is designed to regulate the even spread of grains, cereals, or mixtures over a mesh screen into the Roller Mill. It achieves this by incorporating several key components, including a feeder roll that maintains a consistent flow, a permanent magnet to capture and release ferro particles, and a dual-screen system with adjustable vibration for efficient impurity removal. The high self-cleaning capacity of the screen, along with a bypass valve for redirecting larger particles, minimizes the risk of mill wear and downtime. With a capacity ranging from 25 to 60 tons per hour and a robust steel frame, the Protector Roll is essential for advanced milling operations.
