The Basalt Sand Machine is a specialized crushing equipment designed for processing high-hardness materials like basalt. With its robust crushing capacity, stable operation, and exceptional sand-making performance, it has secured a prominent position in the aggregate industry. Its working principle relies on two high-strength, wear-resistant rollers rotating in opposite directions, crushing large basalt blocks into sand of desired particle sizes through compression and grinding.

Outstanding Sand-Making Performance

The Basalt Sand Machine delivers remarkable results, particularly when processing high-hardness basalt, with the following core advantages:

1. Superior Sand Quality

• Optimal Particle Shape
  The final sand primarily consists of cubical particles with minimal needle-flake content and no internal cracks, meeting high-standard construction requirements. This particle shape enhances concrete strength and durability, making it ideal for high-grade roads, bridges, and other critical projects.
• Controlled and Uniform Grading
  The output particle size ranges from 1-5 mm (adjustable to 0-5 mm). Precise adjustment of the roller gap via a hydraulic system ensures rational gradation, consistency, and minimized over-crushing.

2. High Efficiency and Cost-Effectiveness

• Enhanced Crushing Efficiency
  Utilizing compression and grinding principles, the crusher achieves a crushing ratio of 15:1, with a single-unit throughput of 150-300 tons/hour. Energy consumption is reduced by 30-40% compared to traditional equipment (only 1.0 kWh per ton).
• Durability and Low Maintenance
  Rollers are made of high-chromium alloy or manganese steel, offering compressive strength up to 2000 MPa, low wear rates, extended maintenance intervals, and cost-effective operation.
• Smart Control and Stability
  Equipped with a hydraulic system for remote monitoring, fault alerts, and overload protection, the crusher ensures stable performance even under prolonged heavy-duty operation.

3. Eco-Friendliness and Adaptability

• Environmentally Friendly Design
  A fully sealed structure combined with dust removal systems limits dust emissions to <5 mg/m3 and noise levels to ≤85 dB, complying with environmental regulations.
• Versatility for High-Hardness Materials
  Specifically engineered for basalt (compressive strength ≤250 MPa), it handles materials with moisture content up to 8%, making it suitable for diverse scenarios.

Conclusion
The roll crusher stands out as the preferred equipment in hard-rock sand production due to its high-quality output, energy-efficient operation, and intelligent features. It meets the stringent demands of construction and infrastructure projects for premium-grade sand and aggregates, solidifying its role as a key solution in modern sand-making applications.
