Grain Auger Conveyor is a kind of equipment specially used for conveying grain. It can solve the problems of scattering and low efficiency in the process of transporting grain. It can convey grain at different angles horizontally, obliquely or vertically to ensure that grain can be quickly transported from one place to different places.
Grain Auger Conveyor employs a central shaft helical blade structure to continuously push materials within a closed trough. It operates smoothly, preventing grain breakage, blockages, and dust leakage. It can be arranged horizontally, inclined, or vertically, and multiple units can be connected in series for long-distance conveying. Non-standard customization is supported, allowing for the addition of roller designs and variable frequency motors. It supports 24-hour continuous operation and easily adapts to various grain conveying needs.
The Grain Auger Conveyor offers smooth conveying without damaging grains. Its fully enclosed structure prevents spillage and dust, effectively protecting grain quality and the production environment. It is flexible in installation, occupies little space, operates stably and reliably, and is easy to use, making it an ideal piece of equipment for grain storage, processing, and transshipment.
Convenient to move: The roller design at the bottom of the conveyor can be moved to the designated position at any time.
Strong adaptability: It can adapt to conveying at different angles, with high flexibility and suitable for a variety of process requirements.
No dust pollution: The closed design can avoid scattering and dust pollution during the conveying process.

The Grain Auger Conveyor uses a motor-driven reducer to rotate the auger shaft. The thrust generated by the continuous rotation of the auger blades propels grains such as wheat, corn, and rice directionally along a sealed cylinder. The grains move smoothly inside the sealed cylinder without breakage, spillage, or dust generation, and can be conveyed horizontally, inclined, or even vertically at 90°. The machine operates stably, feeds evenly, and the conveying process is continuous and smooth. It can complete feeding, lifting, and transfer operations, and can also connect to grain silos and processing equipment to achieve automated assembly line operations. With its simple and reliable structure and convenient maintenance, it is the core equipment of a grain conveying system.
The Grain Auger Conveyor mainly consists of a drive motor, reducer, screw shaft, conveyor blades, enclosed cylinder, inlet and outlet ports, and support frame. The overall structure is compact, robust, and durable. The screw shaft and blades work smoothly together, ensuring stable operation without damaging the grains.
Spiral blades: Spiral blades are an important component of the screw conveyor. It is inside the spiral tube. The grain spiral blades are generally axial spirals, which are convenient for pushing grains for transportation.
Conveying trough: The conveying pipeline is the outer shell of the screw conveyor, which is used to accommodate the spiral blades and guide the conveying direction of grains.
Support frame: The support frame is used to support and fix the various components of the screw conveyor to ensure the stable operation of the equipment.
Feed port silo: Mainly used to put and store grain materials to ensure the continuity of grain during transportation.
Discharge port: Responsible for smoothly discharging the grains from the feed port to the designated location.
We offer different types of Grain Auger Conveyors based on our customers' transportation needs, transportation scenarios, and grain characteristics. Customers can choose the one that best suits their needs to ensure the smooth operation of grain transfer.
Hose spiral conveyor: suitable for powdered and granular grains, such as flour, soybean meal, rice bran, feed, etc., using high-strength wear-resistant hoses, can be bent for conveying, and adapt to complex spatial layouts. Fully enclosed conveying to avoid dust spillage, in line with environmental protection requirements. Suitable for short-distance (3-30 meters) and small-batch conveying, easy to move.
Belt conveyor: suitable for granular grains, wheat, corn, rice, soybeans, suitable for long-distance (10-100 meters) and large-scale continuous conveying. The belt is soft and does not damage the grain, especially suitable for seed grain conveying. The maximum inclination angle is ≤25°, which is suitable for loading, warehousing and other scenarios.
U-shaped screw conveyor: suitable for granular and small-block grains, such as corn, wheat, beans, and feed pellets. The U-shaped trough design prevents leakage and is suitable for medium and long-distance transportation (5-30 meters). It can be horizontal or inclined (≤20°) to adapt to different working conditions.
The Grain Auger Conveyor automates the conveying, loading, unloading, and transfer of grains, easily connecting storage and processing equipment. It can quickly complete grain transportation, reduce manual handling, and improve the operational efficiency of grain depots, granaries, feed mills, and other similar facilities.
Conveying grain: The main function is to convey grain from one location to a warehouse, production line or processing equipment, which can be conveyed horizontally, obliquely or vertically.
Conveying of production line: Grain can be conveyed from processing links such as cleaning, crushing, screening, drying, etc. to the next process.
Improve production efficiency: The emergence of grain screw conveyors has greatly reduced the time and labor costs in the material transportation process.
Reduce grain loss: Through stable and uniform transportation, the vibration and loss of grain during transportation can be reduced, and the quality of grain can be maintained.
Grain Auger Conveyor is widely applicable and can transport common grain crops such as wheat, corn, rice, soybeans, sorghum, barley, and oats. It is also suitable for granular materials such as bran, rapeseed, and millet.
Grains: wheat, corn, rice, barley, sorghum, good fluidity, suitable for standard spiral design, need to control the speed to prevent breakage (especially rice)
Beans: soybeans, mung beans, red beans, peas, hard particles, need wear-resistant blades, soybeans are easy to roll, it is recommended to reduce the inclination angle (<20°).
Oil crops: rapeseed, peanuts, sunflower seeds, small particles (such as rapeseed) need to be leak-proof design; peanuts and other fragile materials need to run at low speed.
Whole grains: oats, buckwheat, quinoa, light particles need to reduce the speed to avoid dust
Processing by-products: bran, rice bran, soybean meal, high dust, need closed design and equipped with dust removal interface
Seeds: breeding corn, hybrid rice seeds, strict low damage transportation, double spiral flexible push is recommended (breakage rate <0.3%).
Materials not suitable for conveying
Sticky materials: such as wet flour, grains soaked in syrup (easy to adhere to spiral blades).
Perishable materials: high-moisture grains (moisture content > 18%), which may cause mold and blockage.
Extreme-shaped materials: extra-long fibers (such as straw) or extra-large lumps (such as unbroken corn cobs).
