Grain auger conveyors for animal feed are used in feed processing and animal husbandry to continuously transport materials such as grains and pelleted feed from lower to higher equipment, such as silos or feeding systems, acting as a link between upstream and downstream processes. The equipment uses a rotating screw to achieve inclined conveying, saving space and providing relatively stable operation. Different models correspond to different conveying capacities, with powders reaching approximately 80 tons per hour and pellets typically between 5 and 60 tons per hour. Common pipe diameters are 160–500 mm, and conveying lengths are mostly 3–7 meters, but can be extended according to site requirements. The inclination angle is usually controlled within 20°–45°, and the conveying efficiency is adjusted accordingly when the angle increases. Parts in contact with the feed are mostly made of 304 stainless steel or Q235B steel; wear-resistant models also have a wear-resistant layer on the blade surface, 3–10 mm thick, for long-term use.
The Grain Auger Conveyor for Animal Feed has a compact design, consisting of a power system, conveying pipe, auger blades, inlet, outlet, and support frame. The power system typically uses an electric motor paired with a reducer, providing stable speed and torque during operation. The conveying pipe covers the outside of the auger blades, serving both a sealing function and reducing feed spillage and dust during transport. The auger blades are welded to the central shaft, continuously propelling the material forward as they rotate. The inlet and outlet can be adjusted according to site layout, commonly featuring a quick-assembly structure for easy assembly and disassembly. To accommodate inclined conveying, the support frame and base are reinforced for greater stability during operation.
The Grain Auger Conveyor for Animal Feed offers several advantages suitable for feed production. First, regarding pellet protection, the equipment typically uses thin, one-piece spiral blades and operates at a relatively low speed, generally controlled at 55–120 revolutions per minute. This gentler blade propulsion reduces squeezing and collision between feed particles, helping to maintain pellet integrity. Next, concerning residue and cleaning, the tubular feed trough has a sealed structure with a polished inner wall, preventing material from easily adhering. Combined with a quick-opening cleaning door and detachable parts, routine cleaning is quick and easy, saving time and effort and reducing the risk of feed spoilage. Furthermore, the spiral rotation itself creates a tumbling effect during transport, suitable for simply mixing different feed formulations for more even feed output.
The price of a grain auger conveyor for animal feed varies depending on the specifications and configuration. For example, a stationary model commonly used on small farms, with a tube diameter of approximately 3 inches and a length between 3–5 meters, has a relatively simple structure and generally costs between $300 and $800. Mobile conveyors for medium-sized operations, with pipe diameters of 4–6 inches and conveying lengths of 6–10 meters, offer more powerful configurations and typically cost between $1,200 and $3,600. Models for large-scale farms, with pipe diameters up to 8–12 inches, stainless steel construction, conveying distances exceeding 20 meters, and equipped with automatic control systems, cost between $4,900 and $9,000, depending on motor power, materials, and additional configurations.
Grain auger conveyors for animal feed can be configured to meet various operating conditions in feed processing and conveying. For pellet conveying, a low-speed motor combined with thin-bladed auger blades ensures a smoother propulsion process and reduces pellet compression; for powder conveying, a sealed tubular trough minimizes dust spillage during operation. In areas with high humidity, hot air and dehumidification modules can be added to the equipment to perform simple drying during conveying, reducing the risk of clumping and mold. Considering the varying spaces in farms or processing workshops, the equipment length and tilt angle can be adjusted according to the site, and suitable pipe diameters and motor power can be matched. For roughage or rapidly abrasive feed, wear-resistant layers can be added to the spiral blades and the inner wall of the feed trough to extend its service life.
Grain auger conveyor for animal feed have a wide range of applications, commonly found in poultry, pig, and cattle/sheep farms, used to feed feed towers, directly conveying feed from the ground to elevated silos, reducing manual handling. In feed processing plants, they are also often installed between grinders, mixers, and packaging machines, serving as connecting equipment. Inclined screw conveyors have a compact structure, occupy little space, and offer flexible conveying angle adjustments, making them suitable for environments with limited space in workshops or farming areas. They can improve feeding rhythm, reduce manual operation, and maintain stable feed condition.
