2. Core Product Advantages
Wear-resistant and durable design
Roller shell material: High-chromium manganese steel alloy (containing rare metals) is used, with wear resistance improved by 3 times and a service life exceeding 8,000 hours.
No wear-prone components: Some models (such as the HSZS hammer crusher) feature optimised designs that reduce traditional wear-prone components, lowering maintenance costs by 40%.
Intelligent Control and Environmental Friendliness
Hydraulic Adjustment System: Parameters such as roller spacing and speed can be adjusted in real-time to accommodate materials of varying hardness (limestone compressive strength ≤160 MPa).
Low Dust and Noise: Closed crushing chamber + high-efficiency dust collection system reduces dust emissions by 60% and noise levels to below 85 dB.
Flexible Adaptability
Mobile models: Some models support tyre/track chassis, with relocation time ≤2 hours, suitable for construction sites with frequent relocation requirements.
Multi-scenario coverage: Can process over 200 types of materials such as construction waste, limestone, and river pebbles, with particle size control accuracy of ±2 mm.
3. Typical Application Cases
Construction Waste Recycling
Equipment Configuration: HSZS400×300 Hammer Crusher + Vibrating Screen
Results: Concrete blocks are crushed into 0–50mm recycled aggregate, with a utilization rate of ≥90%, and costs 40% lower than purchasing sand and gravel.
Limestone Sand Making
Equipment Configuration: 2PGY750×500 Double-Roller Crusher + Sand Washer
Effect: Output particle size 2–8mm, cubic particle ratio >85%, used as a substitute for natural sand in C30 concrete.
Coal Gangue Recycling
Equipment Configuration: 2PGT400×250 double-roll crusher + magnetic separator
Effect: Crushed coal gangue is used for brick making, with iron impurity separation rate >95%, meeting environmental standards.
4. Purchase Recommendations and Pitfall Avoidance Guide
Clarify priority needs
Limited budget: Choose a spring-type double-roll crusher (starting at 14,000 RMB), suitable for low-intensity, temporary operations.
High precision requirements: Hydraulic double-roll crusher (starting at 80,000 RMB) or double-tooth roll crusher (starting at 60,000 RMB), with more precise particle size control.
Factory inspection and trial operation focus
Material Inspection: Request a material test report for the roller casing (high-chromium alloy must contain ≥12% chromium).
Testing Verification: Conduct on-site tests to evaluate crushing performance on materials of different hardness levels (e.g., limestone and basalt).
Avoiding Common Pitfalls
Misrepresented Capacity: Request third-party testing reports (e.g., hourly production verification data issued by a third-party institution).
After-sales terms: Clearly define the warranty period (≥1 year), spare parts supply timeline (≤72 hours), and remote technical support.
5. Service and Support
National Service Network: Over 200 service centres, 24/7 response, offering material testing and operation training.
Customised Solutions: Optimise equipment configuration based on material characteristics (e.g., moisture content, hardness) and support non-standard modifications.
Transparent Pricing: Directly reported base prices on the official website (hnhsm.com), with no markups by intermediaries.
Summary
HuaShengMing small rock crushers excel in cost-effectiveness, adaptability, and low maintenance costs, making them particularly suitable for small to medium-sized production lines.
Entry-level recommendation: HSZS400×300 hammer crusher (starting at 22,000 RMB), suitable for primary processing of construction waste;
Advanced recommendation: 2PGY750×500 double-tooth roller machine (starting at 60,000 RMB), meeting high-precision sand-making requirements;
