Multi-Functional Screening Buckets: Revolutionizing On-Site Material Processing
Publish Time: 2025-03-06 Origin: Site
Durability, Precision, and Versatility for Excavators & Loaders
Core Technology: Bi-Directional Drum System
Powered by the host machine’s hydraulic flow (120-320 L/min), our screening buckets feature foot-pedal-controlled drum rotation for precision operations:
1. Dual-Rotation Modes
Forward Rotation (15-25 RPM): Crushes hard materials (glass, bricks, gypsum)
Reverse Rotation (2-3 RPM): Self-cleaning mode prevents clogging in high-moisture clay (up to 40% water content)
Instant Switching: <0.5s transition via torque-sensing automation
2. Sludge-Optimized Design
Spiral blade configuration enhances centrifugal separation
Maintains 95%+ throughput efficiency in wet conditions
Outputs stabilized backfill with ≤12mm particle size
Engineering Excellence
1. Ultra-Durable Drum Assembly
Tungsten Carbide Wear Blocksdian
Material: YG15 alloy (89+ HRA hardness)
5.2X lifespan vs standard manganese steel (ASTM G65 tested)
Modular replacement: <30 minutes per segment
2. Premium Hydraulic Components
Danfoss Motors
10,000-hour MTBF certification
IP69K waterproof rating (-40°C to 120°C operation)
