BUCKET ELEVATOR CONVEYOR

A Bucket Elevator Conveyor is a vertical conveying system used to lift bulk materials safely and efficiently from a lower level to a higher level. It is widely used in industries where powders, granules, or small solid materials need to be transferred in a continuous and dust-free manner.

A bucket elevator conveyor is a system that uses buckets attached to a continuous belt or chain to vertically transport bulk materials like grain, powder, or granules. The buckets scoop material from a lower point, lift it to a higher point, and then discharge the material, either through centrifugal force or continuous discharge. These systems are essential for industries such as agriculture, mining, and manufacturing for efficient, continuous vertical material handling.

The rotary bucket conveyor (referred to as the rotary bucket) is a conveyor that uses two special material chains as traction components, and the two sides of the hopper are fixed on the chains and continuously arranged. It is loaded by inflow and automatically flipped and unloaded at low speed.

Description :- A bucket elevator consists of buckets mounted on a belt or chain enclosed in a steel casing. The material is picked up from the inlet (boot section), lifted vertically, and discharged at the outlet (head section). It is designed for high capacity and compact installation compared to inclined conveyors.

Operational Principle :- The bucket elevator unloading can be divided into three types: centrifugal, gravity, and mixed. The hopper scoops up the material from the storage below. As the conveyor belt or chain rises to the top, it bypasses the top wheel and flips downwards. The bucket elevator dumps the material into the receiving tank. The transmission belt of bucket elevators with transmission generally adopts rubber belts, which are installed on the lower or upper moving rollers and the upper and lower variable direction rollers. Chain driven bucket elevators are generally equipped with two parallel transmission chains, with a pair of transmission sprockets above or below and a pair of variable direction sprockets below or above. Bucket elevators are usually equipped with a casing to prevent dust from flying in the bucket elevator.

Optional configuration :-

Construction of the hoist : Hoists are generally composed of basic components such as motors, reducers, conveyor sprockets, chains, hoppers, etc.
1. Motor: As the power source of the hoist, it is used to provide mechanical energy.
2. Reducer: Converts the high-speed rotation output by the motor into the low-speed rotation required for the conveyor sprocket.
3. Conveyor chain wheel: It is an important component of the elevator, receiving power from the machine and acting on the hopper through chain transmission, carrying animal material upward along the vertical direction of the elevator.
4. Chain: Transfer the power of the conveying sprocket to the hopper.
5. Hopper: used to store and transport materials, transporting them up the elevator.

Product Features :-

The driving power is small, adopting inflow feeding, induction unloading, and dense layout of large capacity hoppers. There is almost no phenomenon of material return and excavation during material lifting, so the ineffective power is low.
Improving this type of elevator requires fewer types and characteristics of materials. It can not only improve general powder and small particle materials, but also improve materials with high grinding ability. It has good sealing performance and less environmental pollution.
The reliability of the entire machine operation has been improved, with a fault free time exceeding 20000 hours. High lifting height. The hoist operates smoothly, thus achieving a higher lifting height.
The feeding of the elevator adopts an inflow type, without the need for a bucket to excavate materials, and there is little squeezing and collision between materials. During the design of this machine, materials are rarely scattered during feeding and unloading, reducing mechanical wear and tear.

🔹 Applications

Food & Agro: Rice, wheat, maize, sugar, pulses.
Cement & Minerals: Clinker, limestone, fly ash, gypsum.
Chemicals & Fertilizers: Crystals, powders, granules.
Pharma & Hygienic Use: Fine powders, specialty chemicals.
Other Bulk Materials: Biomass pellets, sand, coal.

Application :-

Building materials industry: In the transportation of materials such as cement, limestone, gypsum, etc., bucket elevators are the most common and effective conveying equipment. They can transport raw materials from storage tanks or loading equipment to various work sites, while also transporting finished products to warehouses or packaging areas.
Chemical industry: In the chemical industry, bucket elevators are mainly used to transport granular materials such as alumina, potassium sulfate, potassium dihydrogen phosphate, calcium carbonate, etc. It can also be used to transport liquid materials.
Metallurgical industry: In the metallurgical industry, bucket elevators are usually used for material transportation in processes such as ironmaking, steelmaking, and casting, such as iron ore, coke, lime, etc.
Food industry: In the food industry, bucket elevators are mainly used to transport bulk materials such as grains, peanuts, soybeans, and are widely used in fields such as flour processing, feed processing, and dairy processing.
Mining industry: In the mining industry, bucket elevators are usually used to transport bulk materials such as ore and coal from the wellhead to the ground or to other process equipment.
