Mining Crushers
I. Core Product Types and Models
Double-Roll Crusher (Main Model)
Small Series:
2PGT400×250: Capacity 2-10 t/h, output particle size 1-3 mm, motor power 5.5 kW × 2, price approx. ¥25,000.
2PGT400×400: Capacity 5-12 t/h, suitable for wet sticky materials (e.g., clay-bearing gold ore), anti-clogging design.
2PGT610×400: Capacity 5-20 t/h, compatible with construction waste recycling and mobile placer gold mining lines.
Medium Series:
2PGY800×600: Hydraulic adjustment, processing capacity 20-50 t/h, discharge size 5-30 mm, price approx. ¥120,000.
2PGY1000×800: Processing capacity 50-80 t/h, suitable for iron ore pre-crushing.
Large Series:
2PGY1500×1000: Full hydraulic system, processing capacity 150-200 t/h, high crushing ratio, suitable for hard rock (granite, basalt).
2PGY1800×1000: Processing capacity 200-400 t/h, modular design for easy maintenance.
Two-stage screenless series: Specifically designed for high-moisture materials (e.g., coal gangue, shale) with zero clogging risk:
800×600: Processing capacity 35-55 t/h, dual motors 45kW+55kW, discharge size ≤3mm.
1200×1000: Capacity 80-120 t/h, suitable for large-scale sand and gravel aggregate production lines.
Box Crusher: Heavy-duty hammer crusher structure, capacity 50-400 t/h, feed size ≤1200 mm, suitable for medium-hard materials (limestone, iron ore).
PEX Series: e.g., PEX-250×1200, often integrated with double-roll crushers in production lines, processing capacity 40-50 t/h, suitable for coarse crushing of vein gold ore.
2. Core Advantages and Technical Highlights
Wear Resistance and Extended Lifespan
Patented Roll Shell/Hammer: High-chromium manganese steel + rare metal composite material (patent pending), roll shell lifespan exceeds 2 years (processing over 30,000 tons), hammer lifespan increased by 30%.
Hydraulic Protection System: Automatically adjusts pressure to prevent overload, reduces equipment damage, and extends core component lifespan.
Energy-Efficient Design
Low Energy Consumption: Roller crushers consume 15%-20% less energy per unit than traditional hammer crushers. Two-stage hammer crushers eliminate secondary processing.
Wet Material Adaptability: Anti-clogging structure supports direct crushing of materials with 15% moisture content (e.g., muddy gold ore, coal), eliminating pre-treatment steps.
Intelligent Flexibility
Precise particle size control: Roller gap stepless adjustment from 1-20mm; hammer crusher output size (1-50mm) adjusted via impact frame clearance.
Mobile integrated solutions: Select models support PTO (Power Take-Off) drive for tractor power, suitable for off-grid mining areas.
3. Typical Application Scenarios
Gold Mining
Veined Gold Ore: Small double-roll crushers (e.g., 2PGT400×400) perform primary crushing to 10-40mm for leaching; large hydraulic double-roll crushers (2PGY1500×1000) process hard quartz veins.
Placer Gold Ore: Mobile lines integrate double-roll crushers with gravity separators; waterproof designs ensure continuous production during river operations.
Aggregate Production
Manufactured Sand Preparation: Double-roll crushers produce well-shaped output (1-3mm fine sand) with lower over-crushing rates than impact crushers, suitable for high-grade concrete aggregates.
Hard Rock Crushing: Large hydraulic double-roll crushers (e.g., 2PGY1800×1000) process granite/basalt at 400 tons per hour.
Resource Recovery and Environmental Protection
Construction Waste Recycling: Small double-roll crushers (250×400) process waste concrete, producing 1-3mm recycled aggregate and boosting recycling rates by 40%.
Steel Slag Processing: Box crushers perform multi-stage crushing of metal scrap, yielding uniform particle sizes ideal for metallurgical reuse.
