Product Features
Military-Grade Wear Resistance Structure
- Multi-layer composite liner system: base layer uses 16Mn high-strength manganese steel (20mm thickness), work surface features replaceable wear-resistant alloy plates (HRC58-62 hardness), with ceramic inserts in critical impact zones. Triple protection extends liner lifespan to 18,000 operating hours when handling abrasive materials like iron ore - 3 times longer than conventional equipment.
- Box girder main frame: 400×400mm enclosed box girder structure optimized through finite element analysis, increasing torsional stiffness by 150% to ensure 1. 5mm deformation under 300-ton full load conditions.
Intelligent Flow Control System
Laser material flow sensors collect real-time data, working with PID control algorithms to automatically compensate for ±15% material density fluctuations, maintaining preset throughput.
Zero-Clogging Operation Guarantee
- High-angle hopper design: 60° optimal inclination angle with polyethylene lining (friction coefficient 0. 15) eliminates material residue.
- Active anti-bridging system: Built-in high-frequency vibrator (0. 5-3mm adjustable amplitude, 0-50Hz frequency) and rotating plow effectively break arch formations from materials with 18% moisture content.
Maintenance-Friendly Design
- Quick-release components: Wear liners use wedge locking mechanisms allowing tool-free replacement within 15 minutes per plate.
- Centralized lubrication: The hopper feeder features automatic progressive lubrication pumps delivering timed grease to 12 critical bearing points, extending maintenance intervals to 500 operating hours.
Application Scenarios
Ferrous metal Mining
- Materials: Iron ore, manganese ore, chromite
- Conditions: High hardness (Mohs 5-6) with sharp edges causing severe impact wear, typically requiring 200-500t/h capacity.
- Configuration: Heavy-duty hopper feeder models with tungsten carbide composite liners and impact-absorbing idler groups in loading zones.
Cement Production
- Materials: Limestone, gypsum, clinker, slag powder
- Conditions: Dust concentrations exceeding 30g/m³, material temperatures fluctuating 80-200℃.
- Configuration: IP65-rated fully enclosed dust covers, high-temperature bearings (250℃ rated), and static eliminators for explosion prevention.
Grain Processing
- Materials: Wheat, corn, soybeans, feed
- Conditions: Poor material flow requiring food-grade standards without contamination risks.
- Configuration: 304/316L stainless steel contact surfaces, 1. 5kW anti-bridging vibrators, and insect-proof sealing.
Solid Waste Recycling
- Materials: Construction debris, industrial slag, municipal waste
- Conditions: Complex compositions with metal/fiber/plastic contaminants, pH 3-11 corrosive media.
- Configuration: 25mm thick manganese steel liners, auto-reverse anti-jamming function, and 300 m epoxy anti-corrosion coating.
