Huashengming rock crushers feature three core series—dual-stage crushers, hydraulic double-roll crushers, and jaw crushers—covering all scenarios from wet material anti-clogging and precision sand production to coarse crushing of high-hardness rock. The double-stage crusher excels at processing high-moisture materials like sandstone and shale; the hydraulic double-roll crusher stands out in river pebble sand production for its particle size control and energy efficiency; while the jaw crusher offers a cost-effective solution for primary crushing of ultra-hard rocks such as granite. We recommend selecting equipment based on material characteristics (hardness, moisture content), production capacity requirements, and budget. Prioritize hydraulic or intelligent control systems to reduce long-term operational and maintenance costs. Rock Crusher For Sale Near Me ，Choose Huashengming Double Roll Crusher .

1. Core Product Types and Features
Two-Stage Crusher (Screenless Design)
Suitable Materials: Coal gangue, shale, granite, wet clay, and other high-moisture or medium-hard brittle materials.
Technical Highlights:
Dual Crushing: Twin-rotor series design achieves efficient “hammer-crushing + material-on-material” crushing with uniform (adjustable) output particle size.
Clog-Resistant & Moisture-Tolerant: Screenless structure prevents blockages, ensuring stable operation even with materials ≤15% moisture content.
High-Output & Energy-Efficient: Hourly capacity 20-180 tons (e.g., 1600×1400 model), with energy consumption 30% lower than traditional equipment.
Representative Models:
Small: 600×600 (20-30 t/h, 22kW×2);
Large: 1600×1400 (120-180 t/h, 160kW+200kW).
Hydraulic Double-Roll Crusher (Toothed Roll Type)
Suitable Materials: River pebbles, limestone, sandstone, shale, and other medium-hardness materials.
Technical Highlights:
Precise particle control: Hydraulic system adjusts roll gap (output size 2-50mm), achieving 95% particle size uniformity.
Wear-resistant durability: High-chromium manganese steel roll liners last over 2 years, reducing maintenance costs by 50%.
Energy Efficiency: Hourly output 50-450 tons (e.g., 2000×1200 model), energy consumption as low as 60% of industry standards.
Representative Models:
Small: 400×250 (2-10 t/h, 22 kW);
Large: 2000×1200 (300-400 t/h, fully hydraulic drive).
Jaw Crusher (Primary Crushing Choice)
Suitable Materials: Primary crushing of high-hardness rocks like granite and basalt.
Technical Highlights:
Powerful Crushing: Feed size ≤900mm, supports materials with compressive strength up to 160MPa.
Robust Structure: Densely reinforced box design minimizes operational vibration, with noise levels below 85dB.
Representative Models: PE Series (PE-150 to PE-1200), hourly output 2-450 tons.
2. Core Advantages Summary
Wear Resistance Enhancement: Hammer heads/roller liners utilize high-alloy materials (e.g., patented high-chromium manganese steel), extending service life by 30%-50%.
Intelligent Control: Hydraulic models support remote monitoring and automatic gap adjustment, reducing manual intervention.
Energy Efficiency & Environmental Protection: Unit energy consumption reduced by 30%-60%. Dust and noise emissions meet green standards (sealed crushing chamber + dust collection system).
Easy Maintenance: Modular design (e.g., replaceable hammers in double-stage crushers) reduces downtime by 40%.

3. Application Scenarios and Model Selection Recommendations
| Application Scenarios | Recommended Models | Key Parameters | Reference Price Range |
| High-moisture materials (e.g., clay, coal gangue) | Two-stage Crusher | 20-180 tons per hour, clog-free without screen bottom | 50,000–300,000 yuan |
| Fine crushing of medium-hard materials (e.g., river pebbles, sandstone) | Hydraulic Double Roll Crusher | 2-400 tons per hour, adjustable discharge size 2-50mm | 18,000–400,000 yuan |
| Coarse crushing of high-hardness rock (e.g., granite) | Jaw Crusher | Feed size ≤900mm, compressive strength 160MPa | 2,000–250,000 yuan |
| Large-scale continuous sand-making lines | Fully Hydraulic Double Roll Crusher | 100-450 tons per hour, automated control | Over 100,000 yuan |
Selection Tips:
Prioritize wet materials: If moisture content >10%, choose a two-stage crusher to prevent blockages.
Particle size sensitivity: For precise particle control (e.g., sand making), hydraulic double-roll crushers are superior.
Cost control: Small-scale projects may opt for jaw crushers or basic double-roll models (e.g., 400×250 model at only ¥18,000).
4. Considerations
Model Matching:
Two-stage crushers excel at wet materials but require primary jaw crushing for excessively hard materials (e.g., granite).
Double-roll crushers suit medium-hard materials with limited single-unit crushing ratio; multi-stage crushing is needed for ultra-hard rocks.
