Small Automatic Anti-Bridging Screw Feeder and Screw Auger Feeder for Hammer Mill Dosing Systems

This compact automatic horse feed screw feeder adopts a U-shaped inlet with equal or variable pitch. An optional anti-bridging structure prevents material arching. Tailor-made for hammer mill feeding and dosing systems, it is CE & ISO approved and delivers stable, uniform feeding for livestock feed processing.

This automatic horse feed screw feeder relies on the rotating spiral blade inside the U-shaped trough to push granular and powdery horse feed forward. As the screw rotates continuously, materials are guided from the feeding hopper to the outlet at a steady flow rate. The adjustable pitch structure changes the material conveying speed to match dosing requirements. The optional anti-bridging assembly actively breaks material arches and blockages at the inlet, preventing feed accumulation and ensuring uninterrupted, consistent material flow to the downstream hammer mill.

• 1Customizable screw pitch design. The U-shaped feeding section supports both equal pitch and variable pitch configurations. Variable pitch slows down material stacking pressure at the hopper, fundamentally reducing bridging risk, while equal pitch provides stable constant-rate feeding for regular production.
• 2Optional anti-bridging device. It agitates bulk feed at the inlet, solves the arching and caking problems common in coarse horse feed, and guarantees a uniform feeding quantity.
• 3Compact structure with small footprint. This small-size feeder fits limited installation space around hammer mills and dosing lines and is easy to mount and maintain. Access panels are reserved for quick inspection and internal cleaning.
• 4Stable and precise dosing performance. It maintains a steady feeding speed, effectively avoids sudden material surges, protects the hammer mill from overload, and extends the service life of the grinding equipment.
• 5Reliable quality certification. The whole machine complies with CE and ISO9001 standards. It is built with solid welding and tight sealing, reducing dust leakage during feed processing. Multiple material options, including carbon steel and stainless steel, are available for different corrosion resistance and hygiene demands.
• 6Proven global operation experience. Our feeders have been exported to South Korea, Iraq, Denmark, Egypt, South Africa, Vietnam, and other regions, adapting to diverse climates and feed processing conditions.

This screw feeder is mainly developed for livestock feed processing and is especially suitable for horse feed production lines. It serves as the dedicated feeding and dosing equipment for hammer mills. It can also handle other animal feeds such as cattle feed, poultry feed, mixed forage, and grain powder. It widely matches small and medium feed mills, on-farm feed processing workshops, and customized automatic dosing batching systems. It can work independently or connect with silos, hoppers, and grinding machines to form a fully automatic feeding and grinding production unit. Its flexible layout also supports integration with other bulk material conveying systems for agricultural granular and powder materials.
