Horizontal ribbon mixers for animal feed production
Experience precise and efficient mixing with low energy consumption for diverse feed ingredients, ensuring thorough blending of powders and granules in just minutes while maintaining hygiene standards.

The RM Series Ribbon Mixers from Ottevanger Milling Engineers are designed for high-efficiency batch processing in feed and food production. These mixers feature a tulip-shaped housing with internal mixing spirals for optimal material flow in opposite directions, achieving a mixing accuracy of 1:100,000. Ideal for applications in compound feed, pet food, and aquafeed production, they support end-products like cattle feed pellets, dog kibble, and fish meal. With a capacity range from 500 to 12,000 liters, the RM mixers accommodate varying batch sizes. Low rotation speed reduces energy consumption, while the smooth internal construction minimizes contamination risk. Constructed with options for stainless steel and ATEX 22 components, they offer enhanced hygiene and safety in processing environments. The pneumatic outlet and inspection hatch ensure efficient operation and maintenance, making them a reliable choice for feed mill operators and related industries.
