Vertical Bucket Elevator for Grain

What is a Vertical Bucket Elevator for Grain?

A Vertical Bucket Elevator for Grain is a machine that uses uniformly fixed hoppers to vertically and continuously lift grain from a low position to a fixed height of 3-40 meters. To ensure the integrity, cleanliness, and explosion-proof safety of the grain particles, the machine uses slow or medium-speed drive, is made of stainless steel, and has a smooth interior without dead corners to prevent grain residue and mold. It also strictly controls dust concentration to prevent dust explosions. The lifting capacity is 50-500 cubic meters per hour. It is commonly used in grain depots, flour mills, rice mills, feed mills, oil mills, and ports.

What are the applications of a Vertical Bucket Elevator for Grain?

A Vertical Bucket Elevator for Grain can be used for the vertical transfer of various granular and powdery grain materials in the grain industry, replacing inefficient methods such as traditional manual handling and inclined conveyors, realizing a full range of applications for grain storage, processing, transfer, and further processing.

Raw Grain Receiving and Storage: The Vertical Bucket Elevator for Grain lifts raw grains such as corn, wheat, soybeans, and rice unloaded from trucks, trains, or ships to the top of silos or shallow circular bins for storage.

Internal Process Flow: The Vertical Bucket Elevator for Grain connects to equipment such as cleaning screens, destoners, rice hullers, rice mills, and flour mills, completing the vertical transport of grains, saving space and enabling automated continuous production.

Finished Product Processing and Packaging: The Vertical Bucket Elevator for Grain lifts processed flour, rice, broken rice, bran, rice bran, etc., to finished product bins or packaging hoppers, ensuring a clean and orderly workshop.

Drying System Support: Lifting high-moisture grains to the top of the drying tower is a core conveying component of the grain drying line.

Factory Processing Feeding: In deep processing workshops such as starch, alcohol, pressed oil, and puffed food processing, it provides a stable feed to soaking tanks, fermentation tanks, or puffing machines.

What types of vertical bucket elevators for grain are there?

Vertical bucket elevators for grain can be divided into belt-driven and chain-driven types based on their traction components. They differ in the types of grain they can lift and their application scenarios.

Belt-driven vertical bucket elevators for grain are commonly used and inexpensive. They use polyester nylon rubber belts or flame-retardant and anti-static belts as the traction component. The bucket is fixed to the belt, resulting in smooth operation, high speed, low wear, and extremely low grain breakage rate. They are suitable for conveying raw grains, finished grains, and powdery by-products. Lifting heights range from 3-30 meters, and lifting capacities range from 1-200 t/h.

Chain-driven vertical bucket elevators for grain are more expensive. They use high-strength round link chains or plate chains for traction. The bucket is mounted on the chain. They have high tensile strength and good durability, making them suitable for conveying high-temperature grains, such as dried hot grains, high-density grains, or grains with slight abrasiveness, as well as applications requiring extremely high conveying volumes. Lifting heights can reach 50 meters, and the lifting capacity is large.

 

What are the advantages of the Vertical Bucket Elevator for Grain?

The Vertical Bucket Elevator for Grain features a low-speed, stable operation design, paired with a mirror-polished shallow bucket specifically for grain. This ensures gentle scooping and unloading without violent impacts or friction, effectively preventing grain breakage and peeling. The grain breakage rate is less than 0.5%, preserving the commercial value of the grain and solving the problem of severe grain breakage in traditional conveying equipment. The fully enclosed body design with precise sealing at the inlet and outlet prevents grain dust leakage, avoiding grain loss and meeting environmental dust removal standards for grain and oil processing, eliminating the risk of dust explosions and improving the workshop working environment. It can be used for various grain materials, including granular, powdery, and finely crushed grains, making it a multi-purpose machine. For grains with high dust levels, it is also equipped with a dust collection system that collects dust while lifting, preventing environmental pollution.

How does the Vertical Bucket Elevator for Grain work?

The working principle of the Vertical Bucket Elevator for Grain is as follows: Grain enters the elevator base through the feed chute. The base adopts a forward feeding design, allowing the material to flow directly into the digging area, thereby reducing the impact resistance when the bucket digs at the bottom and achieving gentle filling. Subsequently, the drive unit drives the head wheel to rotate, causing the bucket carrying the grain on the traction belt or chain to rise at a constant speed along the shell track. When the bucket reaches the top of the head roller, the material is subjected to the combined action of centrifugal force and gravity, and is ejected from the bucket opening along a specific parabolic trajectory, falling into the discharge chute, completing the emptying process.

Vertical Bucket Elevator for Grain Case

A large corn drying and storage center in Indonesia needed to lift moist corn (28% moisture content) 35 meters to the drying tower inlet, with a processing capacity of 200 tons/hour. They selected a 630mm wide belt-driven Vertical Bucket Elevator for Grain, equipped with a wear-resistant and heat-resistant belt and a buffer base. The linear velocity was controlled at 2.2m/s, with a breakage rate not exceeding 0.2%, resulting in a significant improvement in grain quality.
