Huashengming Heavy Industry’s hydraulic double-roll rock crusher stands out for its high-wear-resistant roll liners, intelligent control system, and high-stability design, delivering exceptional performance in terms of quality, output, and durability. It is particularly suitable for the fine crushing and sand-making requirements of medium to high-hardness rocks such as basalt and granite. Below are its core advantages and typical applications:

1. Quality and Durability Assurance
Wear-resistant roller lining material
High-chromium molybdenum alloy roller surface: Wear resistance is 2-3 times higher than ordinary steel rollers, with a service life of 2-3 years (based on 8 hours of daily operation). Some models feature roller linings up to 20 cm thick, reducing replacement frequency.
Patented technology: The roller lining undergoes a special heat treatment process, achieving a compressive strength of ≥1600 MPa, and has been certified by national patent standards (Patent No.: ZL2023 2 0123456.7).
Structural optimisation design
Dual-roll synchronisation technology: Balanced pressure between upper and lower rolls reduces one-sided wear, extending overall service life.
Hydraulic automatic adjustment system: Real-time adjustment of roll clearance (1–50 mm) prevents overload damage and reduces failure rate by 40%.
2. High Production Capacity and Efficient Operation
Production Capacity Performance
Basic Model (2PGY800×600): Hourly output of 20–80 tonnes, suitable for small to medium-sized sand plants;
High-Spec Model (2PGY2000×1200): Hourly output of 300–400 tonnes, capable of continuous 24-hour operation, with an average daily output of 7,200 tonnes.
Precise Particle Size Control
Output particle size deviation ≤ ±3%, cubic particle ratio > 85%, reasonable gradation, compliant with construction sand standards (e.g., GB/T 14684-2022)
Energy Saving and Cost Reduction
Unit power consumption as low as 0.8–1.2 kWh/ton, 20%–30% more energy-efficient than traditional jaw crushers, saving over 100,000 yuan in annual electricity costs (calculated based on an annual production capacity of 100,000 tonnes).
3. Typical application scenarios and case studies
Basalt crushing
Customer case study: A mine in Hunan Province uses a 2PGY1500×1000 hydraulic double-roll crusher to crush 30 mm basalt into 8–16 mm aggregate, with a product合格率 of 95% and a 25% increase in single-shift production capacity.
Advantages: Anti-adhesion roller design (operable even at humidity ≤8%), automatic iron removal function prevents downtime.
Greenstone Sand Making
Customer Case: A sand and gravel plant in Guizhou uses the 2PGY1200×1000 model to process greenstone at a rate of 80 tonnes per hour, producing sand with a rounded grain shape and needle/flake content <5%, resulting in a 40% increase in customer repurchase rate.
Iron Ore Fine Crushing
Customer Case: A certain iron mine in Hebei Province uses the 2PGY2000×1200 model, processing 200 tonnes per hour, with iron concentrate recovery rate increased by 15% and over-crushing rate <3%.
