hopper feeder

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 300μm epoxy anti-corrosion coating.
