1. Quarry Rock Crushers Analysis of Various Crusher Types
Double Roll Crusher: The Preferred Choice for Precision Sand Production
Working Principle: Double-roll compression crushing with hydraulic/spring-loaded roll gap adjustment (±0.1mm precision), under-crushing rate <10%.
Wear Resistance: Roll shells feature high-chromium manganese steel + rare metal composite layers (triple-layer structure), lifespan >2 years (processing capacity exceeding 30,000 tons).
Application Scenarios:
Small-scale sites: 250×400 model (¥25,000+), 2-10 t/h output, 1-3mm fine sand, ideal for construction waste recycling.
Large-scale sites: 1500×1000 model (¥380,000+), 400 t/h output, AI hydraulic control, produces well-shaped sand from hard rock.
Double-Tooth Roller Crusher: Wet & Sticky Material Specialist
Anti-Blocking Design: Serrated roller surfaces (wolf teeth/wave teeth) enhance gripping force, enabling direct crushing of materials with up to 15% moisture content and near-zero blockage rate.
Flexibility: Adjustable roll gap (1-20mm) delivers wide output size range (10-200mm).
Representative Models:
2PGC400×400: 15-30 t/h capacity, ideal for crushing clayey gold ore and coal.
2PGC1200×1500: 200-300 t/h capacity, 800-1050mm feed size, primary crushing for large mining sites.
Jaw Crusher: Primary Crushing of Large Hard Rock
Crush Capacity: Feed size ≤1020mm (e.g., PE-1200×1500), high crushing ratio (1:10).
Structural Advantages: Simple and reliable design, low maintenance costs, suitable for mobile production line integration.
Cost-Effectiveness: Small-scale model PE-150×250 starts at ¥0.88k, hourly output 1.2-3.5 tons.
Two-stage Crusher: Efficient Processing of High-Moisture, Sticky Materials
Screenless Design: Dual-rotor relay crushing completely eliminates wet material blockage.
Energy Efficiency: 15%-20% lower energy consumption per unit compared to traditional equipment, with hourly output of 35-55 tons (800×600 model).
Applications: Coal gangue, shale, construction waste recycling (output ≤3mm).
