Tianli Building Materials 2,500 TPH Aggregates Production Line

1. Feeding System

• Under-hopper feeding design reduces loading height and energy consumption.
• Vibrating feeder installed at a 14° inclination for high throughput and anti-blocking performance.
• Low operating cost with stable material supply.

2. Dual Parallel Crushing Lines

• Two heavy hammer crushers for primary crushing and one-time shaping.
• Four shaping hammer crushers with adjustable active liners.
• Impact crushing + reshaping in one, delivering better particle shape.
• Low flake content and low powder content to meet high-grade aggregate requirements.

3. Modular Screening Tower

• Prefabricated modular steel structure shortens construction time and improves build quality.
• Separate supports for screen frame / steel structure / accessories: steel structure does not vibrate, improving stability.
• Rotating electric lifting mechanism enables faster maintenance.
• Surrounding inspection walkways support easy巡检 and safe operation.
• Box-type exciters deliver large amplitude with low energy consumption; oil lubrication ensures stable running.
• 4-layer screen replaces traditional 2-screen setup, improving efficiency.

4. Dry Sand Making & Powder Selection Process

• No water washing required, dust-controlled and eco-friendly.
• Compact tower layout uses vertical space to reduce footprint.
• Modular system integrates shaping, conveying, air separation, and dust collection.
• Optimizes gradation and particle shape for higher-quality manufactured sand.
• Fine sand proportion (0.15–0.18 mm) can be significantly increased and adjusted.
• Three-in-one air separation: static + dynamic + fine sand recovery.
• Powder content adjustable between 3%–15%.
• Recovers 0.075–0.6 mm fine aggregates while producing high-value stone powder.

• Materials below 20 mm enter the DLZSJ1618 dual-rotor sand maker for shaping and sand making.
• Two DL2YKZ3680 screens produce 0–5 mm, 5–10 mm, and 10–20 mm finished products.
• 0–5 mm can be sold directly or used as feed for the washing system.
• Materials above 20 mm enter the secondary crushing + finished screening circulation.
• 0–5 mm is conveyed to the DLZXL300 powder selection tower.
• After DLVSI1145 impact crushing and air classification, powder is conveyed to a 7.5 m diameter silo for storage.

5. Sand Washing System

• Water recycling reduces overall water consumption.
• Sustainable and environmentally friendly operation.

• 0–5 mm sand is conveyed to two DL2LXS1890 spiral sand washers.
• Then enters four DLXS3024 wheel bucket sand washers for further washing.
• Followed by four DLXSH2448 fine sand recovery + dewatering units.
• Fine sand loss is controlled within 5%–10%.
• Wastewater: sedimentation tank → lifting tank → concentration tanks.
• Clarified water is recycled to the clean water pool.
• Sludge is pumped to a filter press for dewatering.
• Filter cakes can be reused for backfilling and land reclamation.

6. Storage System

• Four 20 m diameter steel silos (7,500 tons each) for finished aggregates.
• 600-ton crane enables rapid prefabricated installation.
• Three loading lanes with four bulk loaders to improve truck dispatch efficiency.
• Quantitative conveyor + bulk loader improves loading speed and reduces labor costs.
• Weighbridge verification at the plant gate ensures accurate shipping data.
• One 7.5 m fine sand silo (800 tons).
• One 32 m stone powder storage yard (6,000 tons).
• One 32 m washed sand storage yard (6,000 tons).
• 52.5 m × 30 m filter press workshop for mud cake storage.
