Enclosed Pipe Belt Conveyor Dust-Free Bulk Material Transport for Mining, Cement & Power Plants

The Enclosed Pipe Belt Conveyor is a new generation of bulk material handling equipment designed for dust-free, flexible, and long-distance transport.
It combines the advantages of conventional belt conveyors and tubular systems, offering a fully enclosed, curved, and environmentally safe conveying method.

Unlike flat belt conveyors, the pipe-type system encloses the material within a circular belt formed by hexagonal idler sets, preventing spillage and contamination while enabling complex routing with horizontal and vertical curves.

1. Fully Enclosed Conveying
   The tubular belt completely seals off the material from the external environment, ensuring zero dust, no material loss, and protection from rain and wind.

2. Flexible Path Design
   Capable of continuous horizontal and vertical curves, reducing transfer points and optimizing plant layout. Perfect for installations where space or terrain is limited.

3. Steep Inclination Capability
   Handles slopes up to 30° higher than conventional conveyors, suitable for uphill transport and elevated discharge systems.

4. Bidirectional Transport
   Both upper and return belt sections can simultaneously carry materials in opposite directions, increasing system efficiency.

5. Precision Belt Tracking
   The circular tube geometry ensures perfect alignment, reducing idler wear and eliminating belt deviation problems.

6. Low Civil Construction Cost
   No need for enclosed galleries or dust covers — reducing structure weight, space requirements, and installation time.

The system applies a frictional drive mechanism identical to a standard belt conveyor.
Material enters through a feeding chute, then the belt wraps into a pipe shape via six idlers arranged in a hexagonal pattern.
The enclosed material travels smoothly along curves and inclines until discharged at the head pulley. The return belt remains closed, maintaining a clean conveying loop.

• Mining – Coal, ore, tailings, and concentrate transport

• Cement Industry – Clinker, gypsum, fly ash, and raw meal

• Power Plants – Fuel and ash handling

• Ports & Terminals – Bulk cargoes like fertilizer, salt, or grain

• Steel Mills – Safe transfer of powders and additives

• Chemical & Paper Plants – Dust-sensitive materials

Sichuan Xinghe Yongchen Machinery Equipment Co., Ltd. is located in Zigong, Sichuan, a key city in the Chengdu-Chongqing Economic Circle. Originating from the Rong County Hongguang Conveying Machinery Factory founded in 1992, the company restructured in 2006 into Sichuan Zigong Hongguang Conveying Machinery Manufacturing Co., Ltd., and officially renamed itself in 2021 after a merger, entering a new phase of development.

With a registered capital of 25.1 million yuan and a 73,000 m² facility, the company employs 216 staff, including 35 engineers and technicians. It integrates R&D, design, production, and sales, specializing in mining machinery and complete system solutions. Main products include general and mining belt conveyors, tubular and curved conveyors, bucket elevators, screw conveyors, apron feeders, chain conveyors, buried scraper conveyors, and crushing and screening systems.

These products are widely used in industries such as power, coal, metallurgy, construction, chemicals, and transportation, with an annual output value of 1 billion yuan. The company is ISO 9001:2015 and GB/T19001:2016 certified, holds multiple patents, and is a member of the China Heavy Machinery Industry Association. It has received honors including “Sichuan Innovative SME" and “Zigong Advanced Collective in Industrial Reconstruction 2022."

Guided by its core values—“Quality First, Technology Leadership, Premium Service, and Pursuit of Excellence"—the company is committed to building long-term partnerships and driving innovation-led, sustainable growth. With a focus on upgrading traditional industries and embracing new technologies, Xinghe Yongchen is striving to become a modern, high-tech manufacturer in the mining equipment sector.
