It can also serve as a specialized reclaiming supplement for bucket wheel stacker-reclaimers, meeting the global industrial demand for efficient and precise bulk material reclaiming.

Core Functions of Bucket Wheel Reclaimer

The core competitiveness of ZOOMRY Bucket Wheel Reclaimer lies in “high reclaiming precision + wide operating range + strong site adaptability” — addressing the core pain points of power plants’ “precise control of boiler feed” and mines’ “layered reclaiming to avoid mixing”, through the coordinated optimization of the bucket wheel system, slewing mechanism and travel device, it solves the problems of traditional reclaiming equipment such as “large reclaiming deviation, narrow coverage, and difficult adaptation to complex sites”, while meeting global customers’ dual demands for “international compliance and long-term durability”.

Customized Bucket Wheel System

The bucket wheel system is the core execution unit for precise reclaiming. 8-12 bucket wheels are designed in an “equidistant circumferential distribution”, with a single bucket capacity of 0.25-0.71m³, flexibly configurable according to reclaiming scale: small and medium-sized stockyards in power plants (500-1500m³/h) are suitable for 8-10 bucket wheels, while large stockyards in mines (1500-3000m³/h) use 10-12 bucket wheels, combined with an adjustable speed of 5-6r/min, achieving “on-demand reclaiming”. The bucket wheel blades adopt an “arc-shaped bionic design”, different from traditional straight-edge blades, fitting the arc of the stockpile during material grabbing, with reclaiming deviation ≤2%, far below the industry average error of 5%, especially suitable for power plants’ precise requirements for coal feed quantity (avoiding boiler underfeeding or overfeeding). The blade material is 16mm thick Mn13 wear-resistant manganese steel, with a tungsten carbide alloy layer surfacing on the surface (thickness 3mm), improving wear resistance by 180% compared to ordinary carbon steel, capable of withstanding long-term impact from mine ore and power plant coal gangue; the inner side of the bucket wheel is equipped with an “anti-stick material deflector”, coated with polytetrafluoroethylene, with material residue rate ≤0.2%, reducing reclaiming quantity deviation caused by residue and lowering manual cleaning frequency. The bucket wheel drive system is equipped with a “precise torque control” function, monitoring grabbing resistance in real time through torque sensors; when encountering large lumps >500mm in diameter, it automatically reduces speed (minimum 2r/min) and triggers an audible and visual alarm, avoiding bucket wheel jamming or motor burnout, ensuring continuous precise reclaiming.

Full-Angle Slewing Mechanism

The slewing mechanism is key to expanding the reclaiming range. The bucket wheel reclaiming arm supports ±65-360° full-angle slewing, and the discharge arm can be adjusted ±90-±105° relative to the reclaiming arm, combined with 15m upward digging height and 1m downward digging height, covering a stockpile range of 80m in diameter. A single unit can complete dead-angle-free reclaiming from “stockpile edge-center” and “bottom-top” without frequent repositioning. The slewing drive adopts a “dual-motor synchronous control + planetary reducer” combination, with output torque up to 10000N·m and slewing precision ≤0.3°, ensuring reclaiming position deviation within 100mm, meeting power plants’ “fixed-point reclaiming (e.g., partitioned reclaiming of different coal types)” and mines’ “layered reclaiming (avoiding mixing of different grade ores)” precision requirements. The slewing bearing uses a “four-point contact ball bearing” (diameter 3-5m), with a load capacity of 1800kN, capable of simultaneously bearing axial load, radial load and overturning moment during reclaiming, with bearing clearance ≤0.1mm, maintaining slewing precision after long-term operation; the bearing surface adopts “nitriding + sealing” dual protection, improving dust and corrosion resistance by 60%, suitable for high-dust power plants and high-humidity mining environments, with a service life exceeding 60000 hours.

Low Ground Pressure Crawler Travel

The crawler travel system is designed for complex sites in power plants and mines. The crawler drive form can be “hydraulic motor + reducer” or “motor reducer”, with travel speeds divided into “operating mode (0.51Km/h)” and “transfer mode (0-2Km/h)”. Low-speed movement during operation ensures reclaiming precision, while high-speed repositioning during transfer improves efficiency. The track shoe width is 600mm, with ground pressure controlled at 125-193KPa, only half that of traditional wheeled reclaimers, evenly distributing weight on soft ground in power plant coal yards or mine slag accumulation areas, avoiding equipment entrapment and reducing crushing damage to buried pipelines (such as power plant coal conveying pipelines). The track tensioning system adopts “hydraulic automatic adjustment”, real-time monitoring of ground hardness through pressure sensors, automatically adjusting track tension: loosening the track on soft ground (tension 8-10kN) to increase contact area; tightening on hard ground (tension 12-15kN) to reduce track deviation, adapting to different site travel needs. In addition, the track drive wheel and guide wheel adopt “forged steel integral forming”, with tooth surface quenching hardness up to HRC60, extending wear resistance to over 12000 hours and reducing the cost of frequent track component replacement.

Core Components of Bucket Wheel Reclaimer

The long-term reliable operation of ZOOMRY Bucket Wheel Reclaimer, from bucket wheel drive to electrical control system, every component has undergone simulation testing under power plant and mine reclaiming conditions, ensuring adaptation to continuous precise reclaiming needs in global industrial scenarios.

Precise Bucket Wheel Drive Unit

The bucket wheel drive system focuses on “precise speed control + impact resistance”, with drive motor power 75-1100Kw, matched in gradients according to reclaiming scale: 500-1000m³/h suitable for 75-220Kw motors, 1000-2000m³/h for 220-630Kw motors, 2000-3000m³/h for 630-1100Kw motors. The motor adopts “high-efficiency permanent magnet synchronous” technology, with efficiency up to 96.5%, saving 12% energy compared to ordinary asynchronous motors, and equipped with IP55 protection grade and anti-condensation heating device, capable of resisting erosion in high-dust power plants and high-humidity mines. The supporting reducer uses a “hardened planetary reducer”, with transmission efficiency of 97.5%, load capacity 50% higher than ordinary reducers, capable of withstanding instantaneous impact loads when the bucket wheel grabs hard materials (maximum impact torque up to 1.8 times rated); the reducer output shaft and bucket wheel shaft adopt “elastic coupling + positioning pin” dual connection, buffering startup impact while ensuring bucket wheel coaxiality (deviation ≤0.05mm), avoiding reclaiming deviation due to eccentricity. In addition, the drive system is equipped with a “torque monitoring and protection” device, real-time feedback of bucket wheel load; when load exceeds 120% of rated, it automatically reduces speed, and cuts power when exceeding 150%, protecting drive components from damage.

Stable Conveying Connection System

The conveying system, as the core connection for “bucket wheel reclaiming - backend transfer”, focuses on “stable conveying + low residue”: reclaiming conveyor belt width 1200-1600mm, belt speed 2.5-5.0m/s, precisely matched to reclaiming volume — 500-1500m³/h suitable for 1200mm width + 2.5-3.0m/s speed, 1500-3000m³/h for 1400-1600mm width + 3.0-5.0m/s speed, ensuring synchronization of reclaiming and conveying rhythms, avoiding material accumulation and blockage. The conveyor belt adopts “high wear-resistant PVG flame-retardant rubber belt” (thickness 14mm), with longitudinal tensile strength up to 2000N/mm, surface treated with “diamond anti-slip pattern + polishing” dual processing, improving anti-slip performance by 50%, preventing slippage of wet coal or sticky slag during conveying; both sides are equipped with 400mm high “wear-resistant rubber skirts + soft sealing strips”, reducing side leakage, with leakage rate ≤0.5%, meeting power plants’ strict material recovery requirements. The conveying system is also equipped with an “automatic deviation correction + cleaning” combination device: belt deviation correction uses “passive hydraulic centering idlers”, with correction response time ≤2 seconds, avoiding conveying deviation due to belt runout; head and tail each equipped with a set of “heavy-duty polyurethane scrapers + brushes”, cleaning rate up to 99.8%, thoroughly removing residual material on the belt surface, reducing belt wear and extending service life to over 3 years.

Precise Electrical Control and Hydraulic System

The electrical control system focuses on “precise reclaiming path planning”, equipped with a 15-inch high-definition HMI touch screen (supporting language switching in English, Russian, Spanish, Chinese, etc.), capable of storing 5 sets of reclaiming scenario programs (such as power plant “fixed-point coal reclaiming”, mine “layered ore reclaiming”), one-key recall during switching without repeated debugging. The system supports three control modes, all optimized around “precise reclaiming”:

1. PLC fully automatic mode: through laser level meter + infrared positioning sensor, real-time collection of stockpile height and reclaiming position data, automatic planning of reclaiming path (such as “bottom-to-top layered reclaiming” “fan-shaped reclaiming along stockpile arc”), synchronously controlling bucket wheel speed, crawler travel speed and slewing angle, achieving “unmanned” precise reclaiming, with reclaiming quantity deviation ≤3%, suitable for power plant boiler feed precision needs;
2. Remote control mode: equipped with 200m range industrial-grade wireless remote controller (anti-interference compliant with IP67 standard), operators can observe stockpile status in safe areas (such as power plant control room, mine watchtower), real-time adjust reclaiming parameters — for example, during mine layered reclaiming, remotely fine-tune slewing angle to ensure uniform layer thickness, avoiding mixing of different grade ores;
3. Manual mode: quick switch in emergencies, manual interface equipped with “reclaiming quantity warning” function, when detected reclaiming quantity exceeds set threshold (such as 3300m³/h), automatically reduces bucket wheel speed and triggers audible and visual alarm, ensuring precise control. The hydraulic system provides power for crawler travel and slewing mechanism, with the core being a “graded hydraulic pump station” (matched to equipment specifications with total power 166-1410Kw), oil tank capacity 1200-2500L, equipped with quadruple filtration devices (filtration precision 5μm), hydraulic oil cleanliness reaching NAS 7 level, reducing hydraulic component wear, with system annual failure rate below 0.3%. Hydraulic pipelines adopt “stainless steel joints + high-pressure hoses” (working pressure 31.5MPa), excellent corrosion resistance, suitable for high-dust power plants and high-salt fog mines, and pipeline layout uses “modular quick-connect” design, reducing local failure replacement time to within 1.5 hours.

Modular Transportation and Efficient Installation

Addressing the pain points of global power plant and mine projects such as “difficult cross-border equipment transportation and long installation cycles”, ZOOMRY Bucket Wheel Reclaimer adopts a “reclaiming-specific modular disassembly + high-proportion pre-assembly” design, significantly reducing transportation and installation difficulty while ensuring precise reclaiming performance, ensuring rapid project commissioning.

Modular Disassembly

The Bucket Wheel Reclaimer equipment is disassembled into “bucket wheel reclaiming module, slewing drive module, crawler chassis module, electrical control module, hydraulic module” 5 standard units based on the “reclaiming function priority” principle, each unit dimension strictly fitting 40-foot high cube containers (length 12.03m × width 2.35m × height 2.69m): the bucket wheel reclaiming module reduces height to 2.4m through hydraulic folding of the reclaiming arm, weight controlled within 32 tons (15% lighter than similar stacker-reclaimer modules); the slewing drive module integrates slewing bearing and drive motor, weight ≤28 tons; the crawler chassis module is split into left and right parts, each ≤45 tons; electrical control and hydraulic modules are integrated in waterproof boxes (dimensions 1.5m×1.2m×2.0m), requiring no special transport permits. Compared to the traditional integral reclaimer’s “special transport + oversized item customs declaration” mode, cross-border logistics costs are reduced by 40%, and core reclaiming components (such as bucket wheel, slewing bearing) are packaged with “anti-rust + anti-collision” double-layer protection before leaving the factory, with wear-resistant protective film on bucket wheel blade surfaces, avoiding precision damage due to bumps during transportation, suitable for logistics conditions in Europe, Southeast Asia, Africa and other global regions.

Pre-Assembly Before Leaving Factory

85% of pre-assembly work is completed before the equipment leaves the factory, focusing on core reclaiming functions: precise docking of bucket wheel and reclaiming arm (coaxiality deviation ≤0.05mm), no-load debugging of slewing drive system (slewing precision calibrated to ≤0.3°), preliminary connection and sealing test of hydraulic pipelines (72 hours no leakage), pre-setting of reclaiming programs in electrical control system, and 100-hour “simulated power plant/mine reclaiming” full-load trial run (verifying reclaiming quantity deviation, slewing precision), ensuring zero failures during on-site installation. On site, only 3 core processes need completion: first, modular unit splicing, connecting bucket wheel module with slewing module and left/right crawler chassis parts via high-strength bolts (M36, torque 2200N·m), completable by 3 people in 3 hours; second, final docking of hydraulic pipelines and electrical plugs, using “quick-connect joints + anti-misconnection design”, avoiding reverse connection, taking ≤1.5 hours; third, reclaiming precision fine-tuning, calibrating bucket wheel reclaiming position with laser positioning instrument, adjusting slewing angle error, taking ≤1 hour. A skilled team can complete all installation and commissioning within 1.5 days for production, shortening the industry average 3-day installation cycle by 50%, particularly suitable for power plants and mines with “high downtime impact and need for rapid commissioning”. ZOOMRY provides multilingual technical manuals including reclaiming precision calibration guidelines, with manuals highlighting key points (such as bucket wheel coaxiality adjustment, slewing bearing seal installation), along with 24-hour online technical support, assisting customers via video guidance to resolve installation questions without needing professional heavy equipment installation teams.
