2. Analysis of Quality and Production Advantages

Wear-resistant materials and structural design

Roll shell material: High-chromium manganese steel alloy (containing ≥12% chromium), with wear resistance three times that of ordinary manganese steel, and a service life exceeding 8,000 hours.
Dual-roll synchronisation technology: Balanced pressure between upper and lower rolls reduces one-sided wear, extending overall service life.

Efficient Crushing and Intelligent Control

Hydraulic Adjustment System: Real-time adjustment of roller spacing and speed to accommodate materials of varying hardness (e.g., limestone with compressive strength ≤160 MPa).
Automated Operation: A single operator can complete parameter settings and monitoring, reducing labour costs by over 30%.

High Production Capacity and Stability

Continuous Operation Capability: Large-scale models (e.g., 2PGY2000×1200) can operate continuously for 72 hours without failure, achieving an average daily output of 9,600 tonnes.
Low Failure Rate: Modular design reduces downtime for maintenance, with maintenance costs 40% lower than comparable products.

3. Typical application scenarios and cases

Limestone sand making

Equipment configuration: 2PGY750×500 double-tooth roller mill + sand washing machine
Effect: Output particle size 2–8 mm, cubic particle ratio >85%, replacing natural sand for C30 concrete, reducing costs by 25%.

Iron ore crushing

Equipment Configuration: 2PGY800×600 hydraulic double-roll crusher + magnetic separator
Effect: 50 tonnes per hour, iron concentrate recovery rate increased by 15%, over-crushing rate <3%.

Construction Waste Recycling

Equipment Configuration: 2PGY1000×800 double-tooth roller crusher + vibrating screen
Effect: Concrete blocks crushed into 0–50 mm recycled aggregate, utilization rate ≥90%, dust reduction of 60%.

Industry Certification:
• Certified under the ISO 9001 quality management system, with a 3-year warranty on core components (such as roll shafts).

5. Selection Recommendations and Pitfall Avoidance Guide

Select based on needs

Small and medium-sized projects: Choose the 2PGT400×250 spring double-roll crusher (starting at 14,000 yuan), suitable for primary processing of construction waste.
High-precision requirements: Hydraulic double-roll crusher (starting at 80,000 yuan) or four-roll crusher (starting at 60,000 yuan), with more precise particle size control.

Factory Inspection Focus

Material Testing: Request a chromium content report for the roller lining (≥12% is acceptable) to avoid misrepresentation of wear resistance.
Machine Testing: Conduct on-site tests to verify crushing performance on materials of different hardness levels (e.g., limestone and basalt).

Avoiding Pitfalls

Misleading Production Capacity Claims: Require third-party testing reports (e.g., if the claimed hourly output is 80 tonnes, it must be verified through actual testing).
After-Sales Terms: Clearly stipulate a warranty period of ≥1 year, spare parts supply within ≤72 hours, and 24-hour technical support response.
