Basalt Rock Properties and Crushing Solutions

Basalt, a dense volcanic rock with high compressive strength (200-300 MPa) and abrasion resistance, is ideal for high-quality aggregates. Its dark color and angular particle shape make it popular for construction, road base, and concrete mixtures.

Crushing Process and Equipment

A typical basalt crushing line includes:
1. Primary Jaw Crusher: Breaks large basalt blocks (≤1200mm) into 150-300mm pieces. Example model: JC5460 (Feed opening: 1400×1100mm, Capacity: 800-1000 t/h).
2. Secondary Cone Crusher: Further reduces size to 40-70mm. Recommended: HPT300 (Max feed: 230mm, Power: 315kW).
3. Tertiary Impact Crusher (for sand-making): Produces 0-5mm cubical particles. Model: VSI6X1263 (Throughput: 250-380 t/h).

Key Equipment Parameters

Equipment Model Max Feed Size Capacity Power
Jaw Crusher JC5460 1200mm 800-1000 t/h 400kW
Cone Crusher HPT300 230mm 250-500 t/h 315kW
VSI Crusher VSI6X1263 50mm 250-380 t/h (2×250)kW

Screening and Grading Control

Multi-layer vibrating screens (e.g., 3YK3070) separate aggregates into 0-5mm (sand), 5-10mm, 10-20mm, and 20-40mm fractions. Moisture content should be <3% for dry screening.
