Project Features：
The project employs a "crushing + washing" process.
The main products are 0-5mm manufactured sand, 5-10mm gravel, 10-20mm, and 20-31.5mm crushed stone.
The project utilizes a "crushing + washing" process, with the production process as follows:
Mining process flow: Drilling with a down-the-hole drill at the mining face → Medium-deep hole blasting → Loading with a hydraulic excavator → Transporting the ore to the unloading platform at the raw ore stockpile by mining dump trucks.
Processing Area Production Flow: ZGC2050 Feeder → PCZ1820 Crusher → Long Belt Conveyor → Intermediate Silo → ZG1223 Feeder → HCS1523 Impact Crusher → 2YKZ3680S Vibrating Screen → VSI1263 Impact Crusher → ZG1223 Feeder → 3YKZ3680S Screening Machine → Granite Buffer Silo → ZG1223 Feeder → VSI1263 Vertical Impact Crusher → 2YKZ3070S Vibrating Screen → Silo.
Washing Process: Material <5mm from screening enters LXS1890 Sand Washing Machine → XSH2455 Fine Sand Recovery and Dewatering Integrated Machine → Wastewater Collection Tank → Sludge Concentrator → Filter Press.
