Light-Duty Chain Conveyor

Product Overview

The light-duty chain conveyor for solid waste is the first core feeding unit in a solid waste processing line, purpose-built for the continuous conveying of large-volume, heavy-load, and irregular materials. It stably transports lump, bulk, mixed, and various piece goods horizontally or at inclines up to 35 degrees, completely eliminating the industry pain point of conventional belt conveyors being unable to handle oversized, sharp, or heavy-load materials.

The equipment uses high-strength manganese steel integrally stamped chain plates as the load-bearing element, combined with a large-capacity curved feed hopper and a seamless curved transition section, easily accepting direct discharge from loaders and effectively preventing jamming of oversized materials or belt puncture. The drive system employs a hardened-gear reducer motor delivering high output torque and smooth operation, equipped with an automatic tensioning device, chain plate anti-misalignment device, overload protection, and emergency stop system to support uninterrupted 24/7 continuous operation.

The entire frame is welded from Q235 heavy-gauge steel plate, with surfaces treated by sandblasting for rust removal plus epoxy zinc-rich anti-corrosion coating, enabling long-term tolerance of the harsh high-dust, high-humidity, and highly corrosive material environments typical of solid waste facilities. The equipment is highly versatile: beyond its core application in preprocessing and feeding for municipal solid waste, construction and demolition waste, and bulky waste, it is also widely used for conveying various heavy-load materials such as industrial solid waste, mining ores, and building raw materials, making it an indispensable front-end key device for building automated solid waste crushing and sorting lines.

Key Advantages

• Heavy-load impact resistance for extreme conditions: Uses 6 mm thick high-strength manganese steel chain plates, with each plate capable of withstanding impact loads exceeding 500 kg. It can convey oversized and heavy materials such as furniture, large appliances, small appliances, electronics, large kitchen items, and sanitary ware without deformation or fracture, delivering a service life more than three times that of ordinary belt conveyors.

• High incline and high throughput for efficient continuous feeding: Maximum conveying angle of up to 35 degrees, saving over 40% of floor space compared with ordinary horizontal conveyors. The large open feed hopper accommodates various discharge methods including loaders and grab buckets, with a maximum throughput of up to 120 m³ per hour per unit, fully meeting the feeding demands of large-scale solid waste projects.

• Anti-jamming and anti-misalignment for stable, reliable operation: Seamless curved transition section design plus anti-jamming side baffles completely resolve the industry-wide problem of oversized material jamming at corners. Chain plates feature a guide-channel structure paired with an automatic tensioning device, ensuring no misalignment or slippage during operation with an extremely low failure rate.

• Modular and easy to maintain with low total lifecycle cost: Chain plates use a standardized modular assembly design, allowing individual plates to be replaced without disassembling the entire unit. Procurement is convenient and replacement requires no specialized tools. Annual maintenance costs are reduced by over 35% compared with comparable equipment.

Technical Specifications

Application Scenarios

• Municipal Solid Waste Incineration Power Plants: raw MSW preprocessing and feeding, slag conveying

• Construction and Demolition Waste Recycling Projects: pre-crushing feeding of bulky C&D waste, recycled aggregate transfer

• Bulky Waste Dismantling Centers: conveying and feeding of discarded furniture and appliances prior to dismantling

• Industrial Solid Waste Treatment Plants: heavy-load conveying of scrap steel, waste rubber, and industrial offcuts

• Mining and Building Materials: feeding and transfer of ores, limestone, coal, and other bulk materials

• Aged Waste Treatment Projects: preprocessing and feeding of excavated aged waste

Case Study

This series of light-duty chain conveyors has been deployed in volume across more than 40 medium- and large-scale solid waste treatment projects in China. As the first feeding unit in every production line, it handles the continuous conveying of material from the discharge area to the crushing and sorting system.

Representative projects include a 500 t/day MSW incineration plant in Jiangsu, a 1.2 million t/year C&D waste recycling project in Zhejiang, and a bulky waste dismantling center in Guangdong. Since commissioning, all units have maintained a record of zero major failures, completely resolving the issues of conventional belt conveyors being cut by sharp materials and shutting down due to oversized material jamming, ensuring continuous, stable operation of entire production lines. The equipment has earned consistent recognition from numerous environmental engineering companies and project owners, becoming the preferred standard configuration for bulky-material feeding equipment in the solid waste industry.
