Ultra-Long Belt, a Winding Dragon | SBHQ Four-Quadrant Permanent Magnet Multi-Drive System Solution
In the mountainous region of Nanning, Guangxi, a 9.5km ultra-long belt conveyor system winds like a giant dragon. As the core artery of a 10-million-ton annual aggregate production project, this system connects directly to four 5,000-ton port berths, forming an integrated “Mine-Belt-Port” transportation network, effectively solving the bottleneck in aggregate supply for the Guangdong-Hong Kong-Macao Greater Bay Area. This 9.5km downhill belt conveyor system is powered by four 1000kW four-quadrant permanent magnet VFDs, providing the core driving force.
The SBHQ series four-quadrant permanent magnet VFDs are widely applied in mining, machinery, ports, and other industries—especially in energy-feedback scenarios such as downhill conveyors, mine hoists, and cranes. In this 9.5km belt conveyor project, four VFDs operate in coordinated control, ensuring balanced load distribution across the system and enabling one-click startup and synchronized full-line operation.
Key technical features include:▲ Outstanding soft-start performance, with starting torque exceeding 150%
▲ Reliable dust-proof design, adaptable to harsh field environments
▲ Advanced control technology to prevent belt slippage and rollback
▲ Proprietary “anti-voltage dip” feature, enabling frequent start-stop operations
▲ Efficient sine-wave energy feedback, returning over one million kWh of energy
▲ Advanced “N+1” redundancy, allowing full-load output even if one unit fails
Upholding the design philosophy of “Total Brand Service – Satisfaction Plus Surprise”, Hope SLANVERT actively participates in belt conveyor projects—from early-stage design and selection, to manufacturing, site commissioning, and final delivery—with a clear focus on precision fulfillment.
Backed by successful cases such as the 33 km ultra-long belt conveyor in Xinjiang, the Fengdu downhill four-quadrant system, and the Wushan downhill project, SLANVERT’s four-quadrant VFDs demonstrate exceptional performance, ensuring load balance under full load, current imbalance rate under 3%, and 100% compliant energy feedback quality.
At the very moment a SLANVERT engineer triggers the startup test, the drive motors along the 9.5 km belt corridor come alive in perfect sync, sending aggregates smoothly to the port berths at a speed of 4m/s.
This successful commissioning of the 9.5km permanent magnet multi-drive system marks yet another major breakthrough in long-distance downhill belt conveyor four-quadrant multi-drive projects.
With “intelligent drive + green innovation” at its core, SLANVERT is accelerating the mining industry’s shift into a new era of high-efficiency, low-carbon transportation.
