Core Functions & Operating Principles

The Tracked Bucket Wheel Reclaimer from ZOOMRY is a mobile continuous bulk material reclaiming equipment that centers on a high-efficiency bucket wheel excavation system. Its operating principle is built around three synchronized actions: the motor-driven bucket wheel rotates to scoop materials from the stockpile face; the slewing mechanism adjusts the boom angle and position to cover the designated reclaiming area; and the tracked undercarriage provides mobility to reposition across the stockpile. The equipment operates on a coordinated mechanical-hydraulic-electrical control logic – the bucket wheel speed adjusts automatically to material density, the hydraulic-driven track system enables smooth relocation and in-situ steering, and the intelligent electrical system monitors real-time parameters to ensure continuous, precise reclaiming with minimal operator intervention.

Compared to traditional loader-based reclaiming methods, the Bucket Wheel Reclaimer delivers 3-6 times higher efficiency, with a single-unit capacity of 500–3,000 m³/h, making it the preferred solution for large-scale, 24/7 continuous production in mining, port transfer, and industrial stockyard operations.

Key Structural Systems

ZOOMRY's Tracked Bucket Wheel Reclaimer is engineered as an integrated system of five core structural assemblies, each precisely designed for durable, high-precision reclaiming in demanding bulk material environments:

1. Bucket Wheel Excavation System

The reclaiming core, featuring 8–12 bucket wheels arranged equidistantly around a heavy-duty rotor, with single-bucket capacities from 0.25 to 0.71 m³. The blades are fabricated from 16mm thick Mn13 wear-resistant manganese steel with a 3mm tungsten carbide alloy coating, offering 180% greater wear resistance than standard carbon steel. An arc-conforming profile ensures close material contact during scooping, achieving reclaiming deviation ≤2%.

2. Slewing & Luffing Mechanism

The bucket wheel reclaiming arm supports ±65–360° full-angle slewing, with the discharge arm adjustable ±90–±105° relative to the reclaiming arm. This configuration, combined with 15 m upward and 1 m downward digging height, enables a single unit to cover an 80 m diameter stockpile area. A four-point contact slewing bearing (diameter 3–5 m) with 1800 kN load capacity ensures slewing precision ≤0.3°.

3. Tracked Undercarriage (Travel System)

Specially designed for complex, soft, and uneven terrains, the 600 mm wide track plates distribute ground pressure at 125–193 kPa – approximately one-half that of traditional wheeled reclaimers – preventing entrapment and reducing damage to ground surfaces. Travel speed is adjustable between operation mode (0.51 km/h) and transition mode (0–2 km/h).

4. Conveyor Connection System

Designed to ensure smooth material flow from bucket wheel to downstream equipment. The Conveyor Belt widths range from 1,200–1,600 mm, with belt speeds from 2.5 to 5.0 m/s, precisely matched to reclaiming capacity. High-wear-resistant PVG flame-retardant rubber belts (14 mm thickness, 2000 N/mm tensile strength) feature diamond anti-slip patterns and 400 mm high rubber skirts with soft sealing strips, maintaining side leakage rates ≤0.5%.

5. Hydraulic & Electrical Control Integration

The electrical system features a 15-inch HMI touch screen with multi-language support, storing up to five reclaiming scenario programs. The hydraulic system (166–1410 kW pump station, 1200–2500 L oil tank) supplies power to track travel and slewing mechanisms, with quadruple filtration (5 μm accuracy) ensuring system cleanliness at NAS 7 level and an annual failure rate below 0.3%.

Automated Operating Modes

The Tracked Bucket Wheel Reclaimer supports three control modes, all designed to maximize reclaiming precision and operational flexibility:

• PLC Full-Automatic Mode: Laser level meters and infrared positioning sensors collect stockpile data, automatically planning layered or fan-shaped reclaiming paths. The system synchronously controls bucket wheel speed, track travel, and slewing angle, achieving unmanned reclaiming with deviation ≤3% – ideal for continuous, high-volume operations.
• Remote Control Mode: A 200 m industrial-grade wireless remote controller (IP67 anti-interference compliant) allows operators to adjust reclaiming parameters in real time from safe areas, ensuring uniform layer thickness and precise material blending.
• Manual Mode: Available for quick intervention during emergencies, equipped with a reclaiming volume warning function that automatically reduces speed and alerts the operator when loads exceed safe thresholds.

With only 1–2 operators required per shift and intelligent monitoring for real-time blockage and belt deviation warnings, the system significantly reduces labor dependence while maintaining consistent reclaiming quality.

Primary Application Industries

ZOOMRY's Tracked Bucket Wheel Reclaimer is deployed across multiple industrial sectors for precision bulk material reclaiming:

• Power Generation: Coal reclaiming in thermal power plant stockyards, ensuring consistent fuel feed to boilers with minimal degradation.
• Mining & Metallurgy: Ore, coal gangue, and aggregate reclaiming in open-pit mines and mineral processing plants.
• Ports & Terminals: Bulk material (coal, iron ore, fertilizers) reclaiming from large stockpiles for ship-loading operations.
• Cement & Construction Materials: Limestone, gypsum, and additive reclaiming for continuous cement production lines.
• Stockyard Management: Mobile reclaiming across temporary and permanent stockyards without fixed infrastructure.
