Basalt sand-making machines, as crucial crushing equipment in the sand and gravel industry, have gained popularity due to their unique crushing principles and exceptional capabilities in processing basalt. Basalt, a high-hardness and high-density volcanic rock, has long posed technical challenges in crushing operations. So, how effective is the hydraulic double-roll sand-making machine in processing basalt?
The basalt sand-making machine has become the preferred equipment in hard rock processing through its advantages of efficient crushing, precise particle control, wear resistance, and intelligent environmental protection. It reliably delivers high-quality sand and gravel materials for both small-to-medium projects and large-scale industrial production.
The performance of roll-type sand-making machines in basalt processing is remarkable, particularly in handling high-hardness materials. Core advantages can be summarized as follows:
I. Superior Crushing Performance
High-quality particle shape
Using dual-roller compression and grinding mechanisms, these machines produce cubic-shaped sand particles with minimal needle-flake content (<5%) and no internal cracks, meeting strict construction-grade sand standards.
Uniform & controllable particle size
Equipped with hydraulic gap adjustment (1-5mm), they precisely control output size within 0-5mm range while maintaining optimal gradation and minimizing over-crushing and powder content.
High-hardness material adaptability
Featuring high-chromium alloy rollers (compressive strength >2000MPa), they maintain stable operations when processing basalt with compressive strength up to 250MPa.
II. Production Efficiency & Economic Benefits
Powerful processing capacity
Medium-small scale: 80 tons/hour (e.g., Model 1080) with intelligent control systems reducing labor costs
Large-scale production: 150-300 tons/hour (dual-roll models) achieving 15:1 crushing ratio at 1.0kWh/ton energy consumption, 30-40% more efficient than conventional equipment
Low operational costs
Extended maintenance cycles, durable wear parts, and automated lubrication systems significantly reduce overall operational expenses.
III. Intelligent & Eco-friendly Features
Smart control functions
Hydraulic systems enable remote monitoring of pressure and temperature parameters with fault functions, enhancing operational stability.
Green production design
Fully sealed structure with dust removal ensures dust emissions <5mg/m³ and noise levels ≤85 dB, complying with environmental standards.
Low-energy technology reduces carbon footprint and supports wet material processing (moisture content ≤8%).
IV. Application Scenarios & Case Validation
Construction & road engineering: Uniformly shaped sand with high compressive strength suits concrete aggregates and asphalt pavement applications.
Practical case: At a granite processing site, Model 1080 achieved 80 tons/hour output with low failure rates and excellent dust control.
This comprehensive performance makes hydraulic double-roll sand-making machines a technically advanced and economically viable solution for basalt processing.
