1. Project Overview & Site Execution
Operating in the challenging climate of Mongolia, this 100-300TPH crushing line is expertly configured to process highly abrasive Granite into premium construction materials. To balance low wear costs with high-quality output, the plant utilizes a powerful three-stage configuration: a PE Series Jaw Crusher for primary reduction, an HPT Multi-cylinder Cone Crusher for secondary crushing, and a VSI5X Sand Maker for final shaping. This sophisticated closed-circuit system delivers perfectly graded 0-5mm, 5-10mm, and 10-20mm aggregates that exceed the strict requirements of local concrete batching plants.

"The VSI5X sand maker is crucial for us. It perfectly shapes the hard granite into high-quality 0-5mm sand and 10-20mm aggregates, completely meeting local concrete plant standards."
2. Detailed Process Flow & Design Rationale
Due to the extreme hardness of Mongolian granite and the strict requirement for 0-5mm sand, we designed a robust three-stage "Crushing + Shaping" circuit:
- Primary Crushing: The raw granite boulders are fed into the PE-750×1060 Jaw Crusher. Its deep crushing cavity easily reduces large rocks to manageable sizes (~150mm).
- Secondary Crushing: The material is conveyed to the HPT300 Multi-cylinder Hydraulic Cone Crusher. Utilizing the lamination crushing principle, it efficiently crushes the hard rock while keeping liner wear costs low.
- Tertiary Shaping & Sand Making: Crushed stone enters the VSI5X Sand Maker. The "rock-on-rock" technology shapes the particles into perfect cubes and generates a high percentage of 0-5mm sand.
- Precise Screening: An S5X Vibrating Screen separates the final output into 0-5mm, 5-10mm, and 10-20mm. Any oversize material is returned to the VSI5X in a closed circuit.
3. Key Equipment Configuration List
We selected market-leading, durable models to ensure stable 24/7 operation and low maintenance costs.
4. Project Highlights & Value Creation
Low Wear Cost
Using a Cone Crusher instead of an Impact Crusher for the secondary stage dramatically reduces the replacement frequency of wear parts when processing granite.
Perfect Cubical Shape
The integration of the VSI5X ensures that the final 5-10mm and 10-20mm aggregates are free of needle/flake shapes.
Cold Weather Reliability
The lubrication and hydraulic systems are specially adapted to maintain stable 24/7 operation during Mongolia's harsh, freezing winters.
