Solution for a 320TPH basalt crushing and sand production line in Dong Nai Province, Vietnam
01. Why are large quarries in Dong Nai province upgrading to 320t/h crushing lines?
In Dong Nai province, facing highly abrasive basalt and the stringent aggregate standards of the Long Thanh Airport project, inefficient production lines mean high maintenance costs and substandard particle shape. Baili Heavy Industry's customized 320t/h high-configuration crushing line, through a mature three-stage crushing process of "jaw crusher + cone crusher + VSI sand making," achieves:
Capacity Targets: Stable production of 300-350 tons/hour, matching the pace of large-scale infrastructure construction.
Excellent Particle Shape: Controllable fineness modulus of manufactured sand, finished aggregate is cubic, with needle-like and flaky content below 8%.
Hard Rock Buster: Hydraulic cone crusher designed for basalt, increasing the lifespan of vulnerable parts by 30%.
02. Project Background: Precisely Targeting the Infrastructure Opportunity in Dong Nai Province
Dong Nai Province is not only a transportation hub in southern Vietnam but also a large-scale stone reserve base.
Resource Characteristics: Dong Nai is primarily composed of basalt and andesite, rocks with extremely high compressive strength, resulting in rapid wear by traditional impact crushers.
Core Driver: The first phase of Long Thanh International Airport is projected to require 18 million cubic meters of stone. Currently, natural sand mining is prohibited; high-quality manufactured sand is the only compliant profit point in the area.
03. Hardware Configuration: 320TPH Sand Crushing Line Technical Parameters
| Process | Equipment Mode | Core Function |
| Feeding | GZD1300x4900 Vibrating Feeder | Stable feeding, pre-screening of fine materials |
| Primary Crushing | C110/PE900x1200 Jaw Crusher | Large crushing ratio, easily handles <750mm raw stone |
| Medium Crushing | HPC300 Hydraulic Cone Crusher | Specifically designed for basalt, layered crushing, good finished product particle shape |
| Fine Crushing/Sand Making | VSI1140 Centrifugal Sand Making Machine | "Stone-on-Stone" process, combining shaping and high proportion of sand production |
| Screening | 3YK2460/2YK2460 Vibrating Screen | Precise Grading in Multiple Sizes (0-5mm, 5-10mm, 10-20mm, 20-30mm) |
04. Core Advantages: The Power of Industrial Innovation That Breaks the Mold
1. No More Headaches Over Particle Shape: Through the dual optimization of the HPC cone crusher and VSI sand making machine, our production line is not just "crushing stones," but "producing industrial-grade raw materials."
2. Unfazed by the High Abrasion of Basalt: The special wear-resistant alloy we use has a longer lifespan than ordinary manganese steel, reducing the pain of frequent downtime and parts replacement in the scorching heat of Dong Nai province.
3. Modular Quick-Assembly System: Designed for rapid quarry commissioning, the entire line supports modular assembly, reducing infrastructure costs by 15% and shortening the installation cycle by 1/3.
Frequently Asked Questions (FAQ)
Q: Why not use an impact crusher to process basalt in Dong Nai province?
A: Basalt has a high Mohs hardness and high silica content. Impact crusher hammers wear out extremely quickly when processing this type of rock, resulting in maintenance costs per ton that are several times higher than those of cone crushers.
Q: Can this production line produce sand that meets the standards of Long Thanh Airport?
A: Yes. By adjusting the speed of the VSI sand making machine, the fineness modulus and gradation of the manufactured sand can be precisely controlled, meeting Vietnamese TCVN 9205:2012 and other construction sand standards.
Q: How long does it take to recoup the investment in a 320tph sand crushing line?
A: Considering the current premium for manufactured sand and aggregates in the southern Vietnamese market, the estimated ROI (Return on Investment) under full-load operation is approximately 10-14 months.
