Hopper-fed Grinder

The Haarslev Hopper-Fed Grinder is a gravity-fed, high-capacity grinder for fresh or frozen animal by-products. A built-in screw conveyor maintains pressure on the hole plate, while the rifled conical knife housing compresses the material to ensure a consistent particle size. Designed for coarse or fine grinding before further processing, it provides low operating costs, hygienic surfaces, optional separator unit for hard particles, and reliable performance in rendering, pet food and fat-melting plants.
