Double Roller Sand Making Machine DR Series

High-Pressure Double Roller Sand Making Machine  Advantages & Features 

1.High-Efficiency Sand Production

Utilizes two high-strength rollers to crush and shape raw materials (e.g., granite, basalt, limestone) into uniform sand particles.

Adjustable roller gap (0.1–5mm) ensures customizable output size for different applications.

2.Superior Wear Resistance

Rollers made of tungsten carbide or high-chromium alloy for extended durability in abrasive environments.

Replaceable roller sleeves minimize downtime and maintenance costs.

3.High-Pressure Grinding Technology

Generates 50–300 N/mm² interparticle crushing force, improving sand yield and reducing energy consumption by 20–30% compared to conventional crushers.

Produces micro-cracks in particles, enhancing downstream grinding efficiency.

4.Low Dust & Noise Pollution

Enclosed structure with dust suppression system meets ISO environmental standards.

Smooth rolling operation reduces vibration and noise (<75 dB).

5.Smart Control System (Optional)

IoT-enabled monitoring of roller pressure, temperature, and wear for predictive maintenance.

Automated gap adjustment via hydraulic system.

High-Pressure Double Roller Sand Making Machine - Product Uses

1. Artificial Sand Production

Concrete Sand Manufacturing: Produces high-quality, cubical-shaped sand (0.1–5mm) for ready-mix concrete, prefabricated components, and high-strength construction applications.

Asphalt & Road Base Materials: Generates uniformly graded sand for bituminous pavements and highway sublayers.

Dry-Mix Mortar: Provides fine aggregates with low moisture content for premium masonry/plastering mortars.

2. Mining & Mineral Processing

Ore Pre-Crushing: Reduces iron/copper/gold ores to 1–5mm before ball milling, improving grinding efficiency by 15–25%.

Diamond/Kimberlite Crushing: Handles ultra-hard materials (up to 300MPa compressive strength) without contamination.

Industrial Mineral Processing: Crushes limestone (for cement), quartz (for glass), and feldspar (for ceramics).

3. Recycling & Waste Valorization

Steel Slag Reprocessing: Transforms metallurgical slag into 0–3mm construction sand, achieving 90%+ utilization rates.

Construction Waste Recycling: Converts demolished concrete/bricks into recycled aggregates (EN 12620 compliant).

Tailings Sand Production: Processes mine tailings to recover fine particles for backfill or secondary use.

4. Specialty Applications

Foundry Sand: Produces high-purity silica sand (AFS 40–100) for casting molds.

Abrasive Material Processing: Crushes garnet, corundum, or silicon carbide for blasting/media applications.

Battery Raw Materials: Prepares spodumene (lithium ore) and graphite to optimize downstream extraction.
