Summary：Explore our 300TPH granite crushing plant in Vietnam. Featuring the C6X Jaw Crusher and HPT Cone Crusher for high-spec, cubical aggregate production.
Vietnam is an important mining export country in Asia, especially the exportation of Limestone, iron ore, coal, granite and bluestone products. Vietnam’s rapid infrastructure development has created an unprecedented demand for high-quality crushed granite. However, granite’s high quartz content and extreme hardness (Mohs 7+) present a significant challenge: high wear-part consumption and unstable TPH.
This case study examines a recently commissioned 300TPH Granite Crushing Line in Vietnam that successfully balanced high throughput with low operational costs using SBM’s flagship technology.
1. Project Overview & Challenges
- Location: Central Vietnam (High-density Granite Region)
- Material: Hard Granite (Compressive Strength: 200-250 MPa)
- Feed Size: < 800 mm
- Final Products: 0-5mm, 5-10mm, 10-20mm, 20-30mm (High-spec aggregate)
- Required Capacity: 300 Tons Per Hour (TPH)
The client previously struggled with a traditional PE series jaw crusher, which suffered from frequent frame fatigue and low efficiency in secondary stages.
2. Technical Configuration: The "C6X + HPT" Solution
To ensure the 300TPH target was met under the harshest conditions, the following SBM equipment was selected:
Primary Stage: C6X110 Jaw Crusher
The C6X Jaw Crusher was chosen for its non-welded bolted frame. In Vietnam’s tropical environment, welded frames often develop micro-cracks due to thermal expansion and vibration. The bolted structure ensures maximum fatigue resistance.
Performance: Handles the < 800mm feed size with ease, providing a consistent 100mm-150mm discharge to the secondary stage.
Secondary Stage: HPT300 Multi-Cylinder Hydraulic Cone Crusher
Granite requires Lamination Crushing to produce cubical shapes. The HPT300 cone crusher provides the necessary crushing force to break hard granite while maintaining a high percentage of 10-20mm "Gold Medal" aggregate.
Key Advantage: The multi-point hydraulic release allows the machine to pass iron or trap material instantly, minimizing downtime.
3. Performance Results & ROI
After six months of operation, the Vietnam 300TPH line delivered the following results:
- 1. Increased Efficiency: Primary crushing efficiency increased by 22% compared to the old PE series.
- 2. Lower Wear Costs: The high-manganese liners in the HPT300 lasted 15% longer due to the optimized crushing cavity.
- 3. Superior Shape: Flaky and needle-like particles were reduced to under 8%, meeting the stringent requirements for high-speed railway ballast.
Technical FAQ: Vietnam Granite Crushing
Q: Why is the HPT Series better for Vietnam’s granite than single-cylinder cones?
A: Vietnamese granite is exceptionally abrasive. The HPT's multi-cylinder support structure provides a more stable crushing force and better CSS (Closed Side Setting) maintenance, which is crucial for preventing "bowl bounce" in hard rock applications.
Q: What is the typical maintenance schedule for a 300TPH line?
A: Thanks to the centralized lubrication system and backing-free liners, routine maintenance takes 30% less time. We recommend a weekly check of the hydraulic oil and a monthly inspection of the manganese liners.
Q: Can SBM provide local support in Vietnam?
A: Yes. SBM has a dedicated technical service team in Vietnam providing spare parts logistics and on-site engineering support to ensure zero-downtime operations.
Partnering for Profit in Vietnam’s Mining Future
The success of the 300TPH Granite Crushing Plant proves that with the right combination of high-performance technology and localized engineering support, even the toughest granite can be turned into a highly profitable asset. By integrating the C6X Jaw Crusher and HPT Cone Crusher, this facility has set a new benchmark for efficiency and product quality in Central Vietnam.
As the demand for high-spec aggregates continues to rise across Southeast Asia, having a reliable, high-capacity production line is no longer just an advantage—it is a necessity for staying competitive. SBM is committed to helping Vietnamese quarry owners maximize their ROI through smarter engineering, lower maintenance costs, and world-class service.
