Core Advantages of Bucket Wheel Excavator

Impact-Resistant Excavation System

The bucket wheel system of the Bucket Wheel Excavator adopts a "compact impact-resistant arrangement"; 8-12 bucket wheels are flexibly configured according to mine mining scale: 8-10 bucket wheels for small to medium capacity scenarios (500-1500 m³/h), 10-12 for large-scale operations (1500-3000 m³/h); the spacing between adjacent bucket wheels is shortened by 15% compared to general equipment, achieving synchronous capture of hard rock stockpiles, dispersing single bucket load and lowering wear risk. Single bucket capacity is 0.25-0.71 m³, with speed 2-6 r/min stepless adjustable, precisely adapting to materials of different hardness:

During excavation of ores with hardness ≤300 MPa, speed is adjusted to 2-4 r/min; 16 mm thick Mn13 wear-resistant manganese steel blades paired with 5 mm tungsten carbide welding coating, wear resistance 200% higher than ordinary equipment, capable of directly crushing lightly clumped hard materials; during processing of medium-soft bulk materials like coal, speed is raised to 4-6 r/min, with PTFE anti-stick guide plates on the inner side of the bucket wheel keeping material residue rate ≤0.2%, avoiding excavation blockages from wet material adhesion.

Bucket wheel drive power is 75-1100 kW gradient matched; for hard rock excavation, 630-1100 kW high-power motors are adapted, output torque 30% higher than general equipment, capable of withstanding instantaneous impacts from large hard rock blocks with diameter ≤500 mm; for medium-soft bulk material processing, 220-630 kW motors are used, balancing efficiency and energy saving. The motor protection level is upgraded to IP55 + double-layer dust cover, resisting high dust environments in mines; built-in anti-condensation heating device allows stable startup even in -30℃ low-temperature mines.

Full-Domain Dead-Angle-Free Coverage

The Bucket Wheel Excavator achieves dead-angle-free processing of mine deep stockpiles through deep coordination of "operation height + slewing angle": 15 m upward digging height can directly excavate the top bulk materials of common 12-15 m high mine stockpiles, without needing layered stacking; 1 m downward digging height, combined with the bucket wheel's low center of gravity design, can penetrate 1 m deep into the stockpile bottom to excavate residues, reducing stockpile residue by 30% compared to traditional equipment and avoiding secondary processing costs for mine residues.

The bucket wheel reclaiming arm supports ±65-360° full-angle slewing, paired with the track's 0.51 km/h low-speed excavation mode, enabling "fan-shaped excavation" along the stockpile edges to adapt to irregular mine stockpile shapes; a single unit covers an 80 m diameter stockpile area, reducing equipment repositioning times by 90%. The slewing drive adopts a "dual hydraulic motor + planetary reducer" combination, with output torque of 12000 N·m; during hard rock excavation, even under instantaneous impacts, the slewing precision can still be controlled within ≤0.3°, ensuring precise excavation positions and avoiding stockpile collapses; the slewing bearing selects "four-point contact ball bearing + reinforced dust-proof sealing ring," with diameter 3-5 m and load capacity of 2000 kN, effectively blocking mine dust intrusion, with service life exceeding 60000 hours.

Mine Terrain Adaptation: Stable Support for Complex Sites

The track system is customized for complex mine terrains, with ground pressure of 125-193 kPa. Through the "600 mm wide track plate + anti-slip pattern surface of track plate" design, during excavation on soft mine fields (bearing capacity ≤200 kPa), it can evenly distribute the equipment weight (overall machine 65-750 t) to avoid entrapment; the track plate material selects Q690 high-strength alloy steel, after carburizing and quenching treatment (hardness HRC58-62), improving scratch resistance by 80%, capable of resisting wear from sharp ores in mines, with service life exceeding 12000 hours.

The track drive form optionally "hydraulic motor + reducer"; the hydraulic system adopts "anti-pollution specialized design": the oil tank is equipped with quadruple filtration device (filtration precision 5 μm), hydraulic oil cleanliness reaches NAS 7 level, effectively filtering mine dust impurities, with system annual failure rate below 0.3%; the hydraulic pipelines use "stainless steel connectors + high-pressure wear-resistant hoses" (working pressure 31.5 MPa), with excellent impact resistance; during hard rock excavation, pipeline vibration does not cause leaks, adapting to high-load continuous operation demands in mines.

Core Components of Bucket Wheel Excavator

Drive Transmission Core

The bucket wheel drive system is equipped with mine-customized high-torque permanent magnet synchronous motors, power 75-1100 kW, efficiency above 96.5%, energy-saving by 12% compared to ordinary motors. The motor rotor adopts "high-silicon steel sheet + reinforced rib strengthening design," improving fatigue resistance by 40%, capable of withstanding frequent impacts during hard rock excavation in mines; the motor housing is fitted with double-layer dust cover, achieving IP65 dust-proof level to prevent mine dust intrusion leading to failures.

The matching hard-tooth surface planetary reducer achieves 97.5% transmission efficiency, 60% higher load capacity than general reducers; the gear surface undergoes "nitriding + carburizing" double hardening treatment (hardness HRC62), with excellent anti-wear performance; during hard rock excavation in mines, gears do not exhibit pitting or tooth breakage; the connection between reducer and bucket wheel shaft uses "elastic coupling + positioning pin," with the elastic coupling buffering instantaneous impact torque up to 2 times rated, and the positioning pin ensuring bucket wheel coaxiality deviation ≤0.05 mm, avoiding excavation deviations due to eccentricity.

Mine-Specific Conveyor System

The conveyor system is optimized for mine ore conveyance, with reclaiming Conveyor Belt width 1200-1600 mm, belt speed 2.5-5.0 m/s, precisely adapted to excavation volume and ore particle size: for large block ore (diameter ≤500 mm), select 1400-1600 mm belt width + 3.0-5.0 m/s belt speed to avoid ore blockages; for fine particle ore, use 1200-1400 mm belt width + 2.5-3.0 m/s belt speed to ensure smooth conveyance.

The conveyor belt uses 16 mm ultra-thick PVG flame-retardant wear-resistant belt body, 2 mm thicker than general belt bodies, with longitudinal tensile strength of 2200 N/mm; the surface undergoes "diamond anti-slip + anti-scratch" double treatment, improving anti-slip performance by 50%, anti-scratch performance by 80%; sharp ore edges cannot scratch the belt body; both sides equipped with "400 mm high wear-resistant rubber skirts + steel wire frame," with skirt wear life over 2000 hours, side leakage rate ≤0.5%. The system is equipped with "heavy-duty polyurethane scraper + brush" combination; the scraper hardness reaches Shore A90, cleaning rate 99.8%, thoroughly clearing ore debris residues on the belt surface; the rollers select "mine-specific dust-proof rollers," sealing level IP55, service life over 30000 hours.

Intelligent Electrical Control and Hydraulic

The electrical control system centers on "convenience of mine excavation," with 15-inch HMI touch screen supporting multi-language switching, interface focusing on mine excavation parameter settings, storing 5 groups of mine-exclusive excavation programs (e.g., "hard rock excavation," "deep stockpile excavation," "fine particle ore excavation"), with one-click invocation during switching without repeated debugging. The system supports three control modes, all optimized for mine scenarios:

• PLC full automatic mode: Through laser level meter + infrared sensor collecting stockpile height and hardness data, automatically planning layered excavation, arc excavation, and other paths, with excavation volume deviation ≤3%, achieving unattended mine excavation;
• Remote control mode: Equipped with 200 m industrial-grade wireless remote controller (IP67 anti-interference compliant, adapting to strong electromagnetic environments in mines), operators at mine safety platforms observe excavation status, real-time fine-tuning bucket wheel speed and track position—for example, remotely lowering speed during hard rock excavation to avoid jamming, fine-tuning downward digging depth during deep stockpile excavation to reduce residues;
• Manual mode: Quick switch in emergencies, interface equipped with "mine excavation warning" function; when detecting bucket wheel load exceeding 120% rated (e.g., encountering oversized hard rock), automatically reduces speed and alarms to avoid drive system damage.

The hydraulic system provides power for excavation and travel, with the core being the "mine-specific hydraulic pump station," adapted to overall machine power of 166-1410 kW per specifications, oil tank capacity 1200-2500 L, equipped with "oil temperature control + level monitoring" dual protection: automatic cooling startup when oil temperature exceeds 55℃, heating startup when below -10℃, ensuring hydraulic performance under extreme mine temperatures; level monitoring real-time feedback hydraulic oil stock to avoid system failures during mine operations due to oil shortage.

Mine Scenario Deployment Solution

For mine "narrow sites, complex transportation routes, limited lifting equipment" pain points, the Bucket Wheel Excavator from ZOOMRY adopts a "mine-adapted modular disassembly + pre-assembly of excavation functions" design. While ensuring excavation performance, it substantially reduces transportation and installation difficulty at mine sites, ensuring rapid commissioning.

Modular Disassembly

Based on "mine site constraints," the equipment is disassembled into 5 units: "bucket wheel excavation module, track travel module, slewing drive module, electrical control module, hydraulic module," all adapted to 40-foot high containers (length 12.03 m × width 2.35 m × height 2.69 m), with single unit weight after disassembly ≤45 tons (track module), transportable via conventional mine freight vehicles without special vehicles; the bucket wheel excavation module reduces height to 2.4 m via hydraulic folding of bucket wheel arm, passing through mine narrow tunnels (width ≥3 m); electrical control and hydraulic modules are integrated into waterproof dust-proof boxes (dimensions 1.5 m × 1.2 m × 2.0 m), with IP65 protection level to resist dust and rain during mine transport.

Compared to traditional equipment "special transportation + oversized customs declaration," cross-border logistics costs are reduced by 40%; core excavation components (bucket wheel blades, track plates) undergo "anti-rust + anti-collision" double-layer packaging before leaving the factory; wear-resistant protective film is pasted on bucket wheel blade surfaces to avoid precision damage from transport bumps, adapting to global mine logistics conditions.

Strong Excavation Function

Before leaving the factory, the equipment completes 85% pre-assembly, focusing on "mine excavation function": precise docking of bucket wheel and excavation arm (coaxiality deviation ≤0.05 mm), slewing drive system's excavation torque debugging (simulating hard rock excavation load), hydraulic pipeline anti-pollution test (72 hours dust environment sealing test), electrical control system's mine program pre-setting, and 100-hour full-load trial run of "simulated mine excavation" (alternating hard rock, deep stockpile scenarios), ensuring no faults during on-site installation.

At the mine site, only 3 core processes are needed: first, modular splicing, connecting track module and slewing module, bucket wheel module and excavation arm with high-strength bolts (M36, torque 2200 N·m), completable by 3 people in 3 hours; second, hydraulic and electrical docking, using "quick-connect fittings + color-coded anti-error," with different interfaces marked "excavation drive" or "travel drive," taking ≤1.5 hours; third, excavation parameter fine-tuning, calibrating bucket wheel downward digging depth and slewing angle via laser positioner to adapt to mine stockpile layout, taking ≤1 hour. An experienced team can put into operation within 1.5 days, shortening the industry average 3-day cycle by 50%, avoiding mine extraction interruptions due to equipment installation.
