Huashengming mechanical crusher, centered around double-roll crushers, excel in sand and gravel aggregate processing, mining fine crushing, and environmental recycling applications through patented wear-resistant technology, hydraulic intelligent control, and highly adaptable design. The equipment combines three key advantages: extended service life (roller liners lasting 2-3 years), low energy consumption (1-2 kWh per ton of material processed), and strong compatibility (suitable for both wet and hard materials). This makes it an ideal choice for cost reduction and efficiency enhancement in industrial crushing applications.
Mechanical Crusher
1. Core Technical Advantages of Double Roll Crushers
Wear Resistance and Durability
Roll Shell Material: Utilizes high-chromium manganese steel + rare metal alloy (patented technology), with compressive strength ≤160MPa and service life of 2-3 years, reducing maintenance costs by over 30%.
Overload Protection: Integrated hydraulic spring design automatically retracts rolls upon encountering hard objects to prevent damage.
Intelligent Control & Energy Efficiency
Precise Particle Size Adjustment: Hydraulic system enables one-touch roll gap adjustment (1-20mm), delivering uniform output particle size (e.g., 1-3mm fine sand) with under-crushing rate <10%.
Energy-Efficient Operation: Power consumption of only 1-2kWh per ton of material, achieving 30%-50% energy savings compared to traditional crushers, aligning with the “more crushing, less grinding” principle.
High Adaptability
No clogging with wet materials, no jamming with dry materials: Processes coal gangue, construction waste with moisture content ≤35%, or high-hardness granite (≤160MPa).
Multi-functional crushing: Suitable for river pebbles, iron ore, quartzite, construction waste recycling, etc.
2. Mechanical Crusher Main Models and Capacity Configurations
Huashengming double-roll crushers are categorized into three capacity tiers. Users may select spring-type (economy model) or hydraulic-type (smart model) based on requirements:
| Model Series | Representative Model | Processing Capacity (t/h) | Suitable Applications |
| Small equipment | 2PGT400×400 | 2-20 | Startup sand plants, small-scale sand production |
| Medium equipment | 2PGY1000×800 | 20-80 | Conventional sand and gravel aggregate lines |
| Large equipment | 2PGY1800×2000 | 300-400+ | Large-scale mines, intensive production lines |
3. Application Scenarios & Industry Solutions
Aggregate Production
Hard Rock Sand Making: Crushes granite and river pebbles into 0-5mm premium sand with well-rounded particle shape for concrete aggregates.
Case Study: A Sichuan sand plant processing 200 tons/hour uses 2PGY1000×800, producing finished sand meeting high-standard building material requirements.
Mining Fine Crushing & Mineral Processing
Ball Mill Pre-crushing Replacement: Fine crushes iron ore to 1-3mm, enhancing subsequent grinding efficiency while reducing energy consumption by 30%-50%.
Environmental Recycling Sector
Construction Waste Processing: Screenless design of double-stage crushers breaks concrete blocks into recycled aggregates (10-30mm) with 90% utilization rate.
Coal and Chemical Industries
Coal Fine Crushing: Dual-tooth rollers gently crush raw coal, minimizing over-grinding at 150-200 tons per hour.
Chemical Raw Material Processing: Quartz stone crushed to 1-3mm for glass and refractory applications.
