Industrial hammer mill for granulate grinding

Optimize the grinding process in feed production with a high-efficiency solution that reduces particle size to approximately 200 microns, ensuring uniformity in end products like poultry feed pellets and soybean meal.

Grinds and Mills Granules for Feed Production

The Hammer Mills 650 Series from Ottevanger Milling Engineers is an expertly engineered solution for achieving precise granule size in feed manufacturing processes. This series features models like Type 650-375 and Type 650-550, renowned for their solid all-welded construction and anti-vibration design, ensuring seamless integration into feed and grain processing lines. The mills are capable of processing granule sizes up to 20 mm and reducing them to approximately 200 microns, meeting the needs of industries such as animal feed, pet food, and aquaculture feed production.

Equipped with a mechanically driven, fully enclosed vibrator feeder, the system ensures even feed distribution and is complemented by an automatic load control for continuous operations. The Type 650-550’s dual direction of rotation enhances its versatility, while an automatic self-cleaning magnet and stone trap improve efficiency and longevity. With options for ATEX 22 certified components, these hammer mills are designed to handle a variety of materials in a safe and energy-efficient manner, making them ideal for facilities focused on high yield and low energy consumption. Available configurations allow customization to meet specific processing needs, ensuring robust performance in demanding environments.
