What Is a Stacking Conveyor? Features of Stacking Conveyors, Mobile Ship Loaders, and Truck Unloaders

Stacking Conveyor is an industrial equipment designed for automated stockpiling and transportation of bulk materials, enabling vertical lifting, horizontal expansion, and enclosed transport through a continuous belt system. Zoomry Heavy Industry (ZOOMRY) integrates high-strength steel cord belts, SEW/Flender gear motors, and intelligent control technologies into its stacking conveyors to build efficient and durable operational systems. The conveyor belts utilize ST/S6300-grade steel cord cores with a tensile strength of 6,300 N/mm and an 8mm wear-resistant rubber surface, suitable for high-abrasion materials like coal and iron ore. The drive system supports variable frequency speed control from 0.1 to 4.0 m/s, achieving ≥96% transmission efficiency even in extreme environments (-30°C to 50°C). The intelligent control unit combines Siemens PLCs and a 10-inch HMI touchscreen, pre-programmed with 20 stockpiling modes (e.g., conical, linear) and supporting remote monitoring and fault diagnostics.

Zoomry’s stacking conveyors, such as the ZR-SF Series Stacking Conveyor, can achieve a stockpile height of 22 meters in iron ore yards with an error margin of <3%, improving yard utilization by 25% and annual throughput to 12 million tons per unit. Widely used in ports, mines, grain silos, and steel plants, these systems replace manual operations to significantly enhance efficiency and reduce pollution.

Core Advantages of Stacking Conveyors

Zoomry’s stacking conveyors lead the industry with innovations in efficiency, sustainability, and reliability:

1. High Efficiency: The ZRSL-60 Series Mobile Ship Loader achieves a maximum throughput of 3,000 tons/hour, 40% faster than traditional grab systems, ideal for rapid port loading and continuous mining operations.
2. Terrain Adaptability: Hydraulic telescopic chassis enables 360° rotation, fitting narrow spaces in mines and stockyards with a minimum turning radius of 3.5 meters.
3. Eco-Friendly Design: Fully enclosed structures reduce dust emissions to ≤10 mg/m³, complying with ISO 14001 standards, while intelligent frequency conversion systems cut energy consumption by 15-25%.
4. Extended Lifespan: Ceramic-coated rollers exceed 50,000 hours of service life, and CEMA C5-grade idlers reduce maintenance frequency by 30%, lowering long-term operational costs.

Application Scenarios: Industry-Specific Solutions

Zoomry provides customized configurations for diverse industries:
Ports & Terminals: The Mobile Ship Loader adapts to Handymax (35,000-50,000 DWT) and Panamax (60,000-80,000 DWT) vessels. Hydraulic luffing mechanisms adjust clearance heights (8-14 meters), while telescopic arms (10-22 meters) ensure full cargo hold coverage, achieving 3,000 tons/hour loading rates with 90% dust reduction.

Mines & Stockyards: The Mobile Truck Unloader employs hydraulic tipping platforms to unload 100-ton trucks in 30 minutes, handling 2,000 tons/hour. Dual-belt synchronization ensures uninterrupted operations for coal and iron ore.

Agriculture & Grain Silos: Radial Telescopic Stackers feature modular designs for rapid switching between materials like soybeans and corn. Tubular conveyors reduce grain breakage to <0.5%, processing 1,500 tons/day with 80% less loss than traditional systems.

Harsh Industrial Environments: High-temperature models use 200°C heat-resistant belts and ceramic rollers for sintered ore transport in steel plants. Stainless steel frames with nano-coatings resist acid/alkali corrosion, doubling equipment lifespan.

Case Study

In Western Australia’s Pilbara region, an open-pit iron ore mine faced environmental fines and inefficiency—annual capacity needed to rise from 8 to 12 million tons, but traditional grabs caused rampant dust pollution, with 50 workers struggling across three shifts. Zoomry deployed the ZR160SF Mobile Stacking Conveyor and tubular conveyor network:

The steel-arm-like ZR160SF transported iron ore powder at 4.0 m/s, while GPS-guided hydraulic arms stacked materials to 22 meters with ±10cm precision. Tubular conveyors sealed the transport network, slashing dust to 8 mg/m³ and restoring clear skies. Post-deployment, labor was reduced from 50 to 12 workers, saving $2 million annually. Energy consumption dropped to 1.1 kWh/ton, with full ROI achieved in 14 months. Today, the mine processes 32,000 tons daily, surpassing 12 million tons annually, becoming a global benchmark for smart mining. “Zoomry’s solution isn’t just equipment—it’s a revolution in production philosophy,” remarked the mine’s operations director.
