Vertical Bucket Elevator

The Vertical Bucket Elevators designed and manufactured by Jiangteng are distinguished by their stability, durability, and ease of maintenance. We offer specific models optimized for handling common materials with a bulk density of ≤1.5 t/m³; these systems not only enhance lifting efficiency but also significantly reduce the risks of clogging and abrasive wear.

How Does a Vertical Bucket Elevator Work?

1. Feeding: Material enters uniformly through the inlet at the machine base, precisely aligning with the trajectory of the moving buckets to minimize dust generation and spillage.

2. Loading: As the buckets descend to the bottom, they are loaded—either by scooping or by inflow—depending on the material's flow characteristics, achieving a fill rate of up to 95%.

3. Lifting: The fully loaded buckets ascend vertically along the sturdy machine casing, maintaining a stable trajectory free from swaying or spillage.

4. Discharging: Upon reaching the top, the material is smoothly discharged into the outlet—propelled by either centrifugal force or gravity—ensuring a clean, residue-free discharge.

5. Cycling: The empty buckets return along the inner side of the casing to begin a new cycle, enabling continuous, 24-hour operation.

Core Parameters and Flexible Customization

We offer extensive customization options:

Lifting Height: Customizable to meet your specific site requirements, reaching heights of up to 144 meters.

Special Requirements: We provide specialized coatings and configurations, including explosion-proof (Ex d IIB T4 rating), corrosion-resistant, and high-temperature-resistant options.

Non-Standard Design: We support inclined installations (at angles ≤ 15°) as well as modifications to inlet and outlet ports to suit unique specifications.

Jiangteng's Manufacturing Processes

1. Welding Process: Fully automated laser welding ensures weld seams are flat and smooth, thereby fundamentally eliminating material hang-up and clogging issues.

2. Surface Treatment: After sandblasting to remove rust, the machine casing undergoes electrostatic powder coating (with a thickness of ≥60μm) to ensure resistance against acid and alkali corrosion. The buckets undergo carburizing and quenching treatments to achieve a hardness exceeding HRC50, resulting in a threefold increase in wear resistance.

3. Assembly Process: The Vertical Bucket Elevator features a unique modular design in which all components are pre-assembled and commissioned at the factory. On-site installation requires no heavy lifting equipment, allowing the unit to be put into operation within just 2–3 days—significantly saving you both time and installation costs.

4. Inspection Process: Before leaving the factory, every unit undergoes dynamic balancing tests, a 48-hour full-load trial run, and leak-tightness testing to ensure that it is ready for immediate use upon delivery and operates smoothly without any leakage.

Our Core Advantages

1. Higher Conveying Efficiency

Jiangteng’s equipment features an optimally designed hopper with a curved bottom, boosting the filling rate by 15%. Overall conveying efficiency is improved by over 20% compared to traditional equipment, directly reducing your unit energy consumption costs.

2. Greater Operational Stability

The core traction components utilize high-strength imported synchronous belts or chains (with a breaking strength of ≥1000 N/mm²). Coupled with a precision drive mechanism, the average annual failure rate remains below 0.2%, ensuring uninterrupted production.

3. Enhanced Durability

Key wear parts of the Vertical Bucket Elevator—such as the hoppers—are constructed from high-manganese steel, offering a service life of 3 to 5 years under standard operating conditions.

The machine casing’s anti-corrosion coating comes with an 8-year warranty, significantly reducing your long-term maintenance and replacement costs.

4. Flexible Configuration

Whether you are undertaking a small-scale retrofit or a large-scale new construction project, we can provide a tailored solution. We offer flexible, one-on-one customization options regarding lifting height, throughput capacity (starting from 10 t/h), and installation methods.

5. Comprehensive Safety

Integrated features include overload protection, automatic blockage alarms, and reverse-rotation clearing capabilities. Additionally, the equipment is fitted with fully enclosed protective guards, ensuring full compliance with industrial safety standards and safeguarding both the machinery and personnel.

Industry Applications

Building Materials Industry: Features a dust-proof and leak-proof structure, making it ideal for handling powdery materials like cement and lime, thereby contributing to a cleaner and more hygienic workshop environment.

Chemical Industry: Utilizes anti-static and corrosion-resistant materials to safely convey substances such as chemical fertilizers and plastic pellets, effectively eliminating contamination risks and safety hazards.

Feed & Environmental Industries: Offers specialized anti-corrosion and anti-sticking solutions tailored for unique materials—such as soybean meal and sludge—ensuring smooth, obstruction-free conveyance.

FAQ

Q: Is the equipment stable when the lifting height exceeds 50 meters?

A: It is completely stable. We utilize a multi-section, high-strength barrel structure with flanged connections, alongside a synchronized upgrade to the drive system. We have numerous successful installations exceeding 80 meters in height, all operating with exceptional smoothness.

Q: What can be done if wet or sticky materials tend to adhere to the buckets during transport?

A: We offer optional Teflon non-stick coatings for the buckets. Additionally, an automatic scraping and cleaning device can be installed at the bottom of the unit to effectively resolve issues related to material adhesion and clogging.

Q: Is the Vertical Bucket Elevator noisy during operation?

A: Featuring a low-noise motor and a vibration-dampening base design, the operating noise level is kept below 75 dB—surpassing industry standards—thereby creating a more favorable working environment.

Q: Is long-term maintenance complicated?

A: Maintenance is simple. Routine maintenance merely requires periodic checks of the tensioning system and replenishing the lubricant once every six months. The modular design ensures that the replacement of key components is both quick and convenient.
