1. Sand-making Advantages and Core Technologies
High-efficiency sand-making performance
Flexible output particle size: By hydraulically or mechanically adjusting the roller spacing, the sand particle size can be precisely controlled within the range of 0.2–20 mm, meeting different gradation requirements.
High sand production rate: The finished sand has excellent particle shape (multiple edges and corners, few needle-like or flake-like particles), low stone powder content, and a sand production rate of up to 98%, meeting the standards for construction sand.
Wet material processing capability: The screenless design prevents blockages, enabling stable operation even when processing materials with a moisture content of up to 15% (such as river pebbles or coal gangue).
Wear-resistant and durable design
Roll shell material: High-manganese steel or alloy wear-resistant liners are used, which undergo heat treatment to achieve high compressive strength, extending the service life by over 30% compared to ordinary equipment.
Core component protection: Bearings and transmission systems are equipped with heavy-duty configurations, supporting 24-hour continuous operation and reducing maintenance frequency by 40%-50%.
2. High-output model recommendations (hourly output ranging from 4 to 400 tonnes)
Below is a comparison of Huashengming’s main double-roll crusher models and technical parameters:
| Model | Type | Hourly Output (t/h)) | Application Scenarios | Core Features |
| 2PGY1000×1000 | CNC Hydraulic | 80-150 | Medium-sized sand plant | One-button start/stop, automated control |
| 2PGY1200×1200 | CNC Hydraulic | 100-200 | Large-sized sand plant | Highly wear-resistant roll liners, low failure rate |
| 2PGY1500×1000 | CNC Hydraulic | 120-250 | Large-sized sand plant | Dual motor drive, 15% energy savings |
| 2PGY2000×1000 | CNC Hydraulic | 150-400 | Ultra-large production line | IoT remote monitoring, customisation available |
Note: All of the above models support customised configurations (such as diesel power and mobile design), and the proportion of fine sand below 2 mm in the output exceeds 85%, making them particularly suitable for high-quality manufactured sand production.
3. Quality assurance and technological innovation
Manufacturing process
Precision machining: The roller surface gears are machined using CNC machine tools, ensuring high meshing accuracy and reducing vibration and noise.
Welding Technology: Laser welding ensures a robust overall structure with seamless connections, extending the equipment’s service life.
Smart Control
Integrated PLC automation system monitors bearing temperature and load status in real-time, automatically shutting down to protect against overloads.
Optional IoT modules enable remote monitoring of production data and fault diagnosis via mobile devices.

4. Environmental and Cost Advantages
Low Dust and Low Noise: Sealed structure + optional dust collection system, dust emissions comply with national standards; operating noise ≤75dB.
Low Overall Cost: Compared to similar equipment, energy consumption is reduced by 20%, maintenance costs are reduced by 40%-50%, and the investment payback period is short.
Summary
The Huashengming double-roll crusher, with its high sand production rate, flexible control, durability, and energy efficiency, is an ideal choice for manufactured sand production. It is recommended to select large hydraulic models such as the 2PGY1200×1200 or 2PGY2000×1000 based on production capacity requirements, and to visit the factory for on-site testing.
