The 4,000 tons per day sand and gravel production line is a newly built project designed to produce aggregates such as 12, 13, and 05 stone. Construction started in October 2017, with a total construction period of 45 days.
• Location: Duyun City, Guizhou, China
• Raw Material: Limestone
• Capacity: 4,000 tons per day
• Finished Products: 12, 13, 05 aggregates
The project site features a compact layout and a streamlined production process. The production line operates efficiently with stable performance and easy maintenance, ensuring reliable aggregate output.
| Equipment | Model | Quantity | Capacity (tph) |
|---|---|---|---|
| Vibrating Feeder | ZG1538 | 1 | 400–700 |
| Heavy Hammer Crusher | PCZ1615 | 1 | 400–800 |
| Vibrating Screen | 4YKQ2460 | 2 | 240–300 |
| Belt Conveyor | — | Several | — |
The limestone raw material is fed into the ZG1538 vibrating feeder, then conveyed to the PCZ1615 heavy hammer crusher for primary crushing.
Qualified aggregates are sent to the finished product stockpile, while oversized materials are returned for secondary processing.
• Simple production line design eliminating secondary crushing stage
• Up to 40% cost reduction compared with traditional solutions
• Scientifically designed process with high crushing efficiency
• Uniform finished products with excellent particle shape
• Easy maintenance and low operating workload
This project adopts an optimized aggregate production solution that balances capacity, efficiency, and operating cost. The streamlined design improves overall productivity while ensuring stable long-term operation.
