Design Capacity: 200 t/h
Finished Product Specifications: Multi-grade aggregates (0–5 mm, 5–10 mm, 10–20 mm, 20–31.5 mm)
Core Equipment: GZG1245 feeder, PE750×1060 jaw crusher, CH430 single-cylinder hydraulic cone crusher, 1145 vertical shaft impact crusher, 3YK2160 triple-deck circular vibrating screen
I. Project Background and Customer Requirements
In recent years, infrastructure development in Myanmar has accelerated, driving a surging demand for high-quality manufactured aggregates. With natural sand resources limited, manufactured sand and crushed stone have become the primary market supply. However, Myanmar’s complex mountainous terrain and long rainy seasons pose challenges; traditional fixed aggregate production lines typically require 2–3 months from civil engineering to commissioning, entailing high infrastructure investment and significant schedule risks.
To meet the customer's core objectives of rapid commissioning and capturing market share—while addressing the high hardness and abrasiveness of granite—we tailored a modular crushing and screening solution. Ultimately, the entire 200 t/h production line was assembled and test-run in a record-breaking four days following equipment delivery.
II. Targeted Process Design: Three-Stage Crushing + Modular Containerization
Granite is extremely hard; using a hammer crusher would result in rapid hammer wear and frequent downtime. Therefore, this project utilizes a "three-stage crushing + one-stage screening" process specifically designed for hard rock:
Process Flow:
Raw material → Pre-screening feeder → PE Jaw Crusher (primary crushing) → CH430 Single-cylinder Cone Crusher (secondary crushing; utilizes inter-particle crushing for wear resistance) → 1145 Vertical Shaft Impact (VSI) Crusher (tertiary crushing and shaping; "stone-on-stone" impact improves particle shape) → Triple-deck circular vibrating screen (grading) → Four product specifications.
Five Major Independent Modules:
The entire line is scientifically divided into five independent modules: feeding, primary crushing, secondary crushing, tertiary crushing/shaping, and screening. Each module undergoes pre-assembly and commissioning at the factory. The equipment utilizes skid-mounted steel structural bases; upon arrival at the site in Myanmar, only simple ground hardening is required before standardized lifting and connection can take place, perfectly suiting the requirements for multimodal (sea and land) transport via standard shipping containers.
III. 4-Day Assembly Record: From Empty Lot to Operational Plant
Day 1: Site preparation and positioning of the feeding module. Simple ground hardening was completed on-site; the feeding module was the first to arrive and was positioned directly using its skid-mounted base, eliminating the need for a concrete curing period.
Day 2: Hoisting of the core primary crushing module. The PE750 jaw crusher module—the heaviest component of the line—was put into position. It was quickly connected to the feeder via a prefabricated short conveyor gallery, with elevation adjustment and anchoring completed within half a day.
Day 3: Sequential positioning of secondary and tertiary crushing modules. The cone crusher and VSI crusher modules arrived one after the other. Thanks to factory-pre-installed piping and electrical interfaces, on-site work required only the connection of inclined conveyors to rapidly link the secondary and tertiary crushing stages.
Day 4: Closed-circuit screening connection and full-line trial run. The vibrating screen was positioned and connected to the VSI crusher. Electrical wiring and commissioning for the entire line were completed that afternoon, and the no-load integrated trial run was successful on the first attempt!
IV. Key Benefits for the Customer
1. Seizing market opportunities: On-site assembly took only 4 days—saving nearly two months compared to traditional methods—enabling the customer to supply products ahead of the peak infrastructure construction season. 2. Infrastructure costs slashed by over 30%: Eliminates the need for massive concrete foundation pouring, ensures operations continue uninterrupted during the rainy season, and significantly reduces upfront sunk costs.
3. 15% premium for high quality: Combines cone crushing and vertical shaft impact crushing for superior particle shaping; over 90% of the finished aggregate is cubical, meeting high-specification concrete standards and commanding a 10–15% price premium over standard aggregates.
4. Low-barrier O&M and high mobility: System energy consumption is reduced by approximately 15%; should the quarry site need to relocate, the entire modular system can be rapidly dismantled and reinstalled, ensuring high asset retention value and recyclability.
V. Conclusion
Rapid construction, stable operation, easy relocation, and flexible scalability.
The successful implementation of the 2025 granite project in Myanmar vividly demonstrates the practical effectiveness of modular solutions in hard-rock processing. For emerging infrastructure markets, this represents more than just a crushing equipment setup—it is an optimal investment strategy characterized by an asset-light model, rapid turnover, and high flexibility.
