Feed pellet crumbler
Achieve precise size reduction of feed pellets with high efficiency and minimal fines, optimizing your production line’s overall performance.

Reduces Pellet Size to Uniform Crumbles
The Crumblers HE-serie from Ottevanger Milling Engineers is engineered to deliver precise size reduction and high-efficiency processing in feed and grain operations. Utilizing dual, independently driven 300 mm rollers, it effectively reduces pellets into uniformly sized crumbles, minimizing fines and maximizing production consistency. Ideal for feed and pet food producers, the Crumblers HE-serie is capable of handling a range of materials, including chicken feed crumble and dog food kibble, with a throughput of up to 40 tons per hour, depending on product specifications.
Its robust construction includes a mild steel housing and hard cast iron rollers, ensuring durability and resistance to wear. The machine offers manual or remote roller adjustment, enhancing operational flexibility and enabling rapid adaptation to varying production needs. Designed for continuous operation, the Crumblers HE-serie integrates seamlessly into existing production lines, supported by high-efficiency mode for reduced energy consumption.
Maintenance and cleaning are streamlined by the large inspection hatch and easily accessible components, while die springs provide a protective safety mechanism against foreign objects. The Crumblers HE-serie can be customized with frequency-controlled dual rotation feeders and additional roller revision options, allowing for tailored configurations to meet specific production demands. Suitable for various feed applications, it meets industry standards and is supported by comprehensive engineering support from Ottevanger.
