Environmentally Friendly Clinker Ship Unloader Suppliers

Environmentally Friendly Clinker Ship Unloader Manufacturer

As a Environmentally Friendly Clinker Ship Unloader Suppliers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

Hangzhou Aotuo Mechanical and Electrical Co., Ltd. (AOTUO) is a China-based manufacturer and supplier of continuous screw-type ship unloaders, specializing in environmentally friendly cement clinker handling. With over 20 years of engineering and manufacturing experience, we supply fixed, rail-mounted, and tire-mounted unloaders that combine high unloading efficiency with stringent dust control. Our equipment is designed for ports, cement plants, and bulk terminals that need to handle clinker, cement, and similar abrasive materials while meeting modern environmental standards.

We are the drafting unit for the industry standard JC/T 2575 "Bulk Cement Spiral Unloader," and our products are exported to Australia, the Philippines, Vietnam, Indonesia, Bangladesh, and other countries along the Belt and Road. Our unloaders are built to handle vessels from 500 to 100,000 DWT with capacities from 300 to 1500 t/h, and we offer complete integration with your existing conveyor and dust collection systems.

Our Product Range for Clinker Unloading

We offer three main configurations in this category, each suited to different berth layouts and operational requirements:

All models are available with capacities from 300 to 1500 t/h and can handle vessels up to 100,000 DWT. We also supply related equipment such as cement screw ship unloaders and coal ship unloaders for other bulk materials.

Dust Control: Integrated by Design

Clinker unloading generates fine dust that must be contained to protect workers and the surrounding environment. Our environmentally friendly clinker ship unloaders are designed with a fully enclosed conveying path from the ship's hold to the dock conveyor. This includes:

• Enclosed spiral conveyor: The gantry and vertical screw are fully covered, preventing dust escape during transfer.
• Vacuum cleaning system: High-power fans create negative pressure at key points like the discharge port and transfer points, capturing dust before it can spread.
• Dust suppression spray: Fine water mist nozzles are positioned above the unloading area to agglomerate airborne particles and accelerate settling.
• Automated control: The system adjusts suction and spray intensity based on real-time dust concentration, optimizing energy use while maintaining compliance.

These measures ensure that dust emission concentrations remain far below national and industry standards, even under full-load operation. Our approach is backed by our experience as a leading Environmentally Friendly Cement Clinker Ship unloader manufacturer.

Engineering and Customization

Every clinker unloader we supply is engineered to match the specific vessel sizes, berth constraints, and throughput targets of your project. Our in-house team covers process, steel structure, mechanical, hydraulic, automation, and IT disciplines, allowing us to provide a complete solution rather than just a machine.

Key customization parameters include:

• Reach and clearance: We adjust the boom length and gantry height to suit your berth and vessel beam.
• Capacity and speed: We size the screw diameter and drive power to achieve your required unloading rate.
• Material handling: For clinker, we use wear-resistant liners and hardened screw flights to extend service life.
• Automation level: Options range from manual operation to semi-automatic and fully integrated control with your terminal management system.
• Environmental extras: We can add centralized dust collection, seawater-resistant coatings, or explosion-proof components if needed.

We also offer a range of auxiliary equipment such as dust collectors and conveyors to complete your transfer system.

Quality Assurance and Testing

Our manufacturing facility in Hangzhou covers 35,000 square meters and includes an A-level production workshop of 14,000 square meters. We hold certifications for quality management (ISO 9001), environmental management (ISO 14001), and occupational health and safety (ISO 45001).

Before delivery, each unloader undergoes:

• Structural inspection: Welds and steel structures are checked to ensure integrity.
• Mechanical run test: The screw and drive systems are tested for smooth operation and alignment.
• Dust system test: We verify the vacuum and spray systems achieve the specified dust control performance.
• Electrical and control check: All sensors, interlocks, and control logic are validated.

We also provide documentation including drawings, operation manuals, and test certificates to support your project acceptance.

Installation, Service, and Support

Our service team provides on-site installation supervision, commissioning, and operator training. We offer a 24/7 technical hotline and commit to a 1-hour response and 6-hour solution for urgent issues. For overseas projects, we work with local partners to ensure timely support.

We also provide predictive maintenance solutions using online fault diagnosis and data analysis to reduce downtime and extend equipment life. Spare parts are available for the long term, and we can set up scheduled inspections to keep your unloader running at peak efficiency.

Information We Use to Configure Your Solution

To prepare a detailed proposal and quotation, we need the following project information:

• Material characteristics: Bulk density, angle of repose, moisture content, and abrasiveness of the clinker.
• Vessel details: Typical vessel size (DWT), beam, draft, and number of hatches.
• Required unloading rate: Average and peak capacity in tonnes per hour.
• Berth layout: Available rail gauge, quay height, and distance from ship to storage area.
• Environmental requirements: Local dust emission limits and any specific regulations.
• Power supply: Available voltage and frequency.
• Integration needs: Existing conveyor systems, control systems, or dust collection infrastructure.

With this information, we can provide a tailored solution that meets your performance and environmental goals.

Frequently Asked Questions

Q: How does your clinker unloader control dust during operation?

A: Our unloaders use a fully enclosed conveying system, a vacuum cleaning system with negative pressure suction, and a dust suppression spray system. These work together to capture dust at the source and suppress any remaining particles, keeping emissions well below regulatory limits.

Q: What is the maximum unloading capacity you can offer?

A: For environmentally friendly clinker unloaders, we offer capacities from 300 to 1500 t/h. For other materials like coal, we can go up to 3000 t/h. The exact capacity depends on the material properties and your operational requirements.

Q: Can your unloaders handle vessels of different sizes?

A: Yes, our unloaders are designed to handle vessels from 500 to 100,000 DWT. The specific range depends on the model and configuration. For example, our rail-mounted and tire-mounted models can move along the berth to access different hatches.

Q: Do you provide installation and after-sales support overseas?

A: Yes, we provide on-site installation supervision and commissioning. We have a global service network and have exported to countries like Australia, the Philippines, and Vietnam. Our team offers 24/7 technical support and can dispatch engineers as needed.

Q: What is the typical lead time for a custom clinker unloader?

A: Lead time varies based on the configuration and customization level. After we receive your project details, we will provide a specific schedule. Generally, it ranges from several months to a year, depending on the complexity and our production load.
