Vibrating Screen Design Principles in Crushing and Sand-Making Lines

Vibrating screens are critical in aggregate production, ensuring efficient material classification. Key design principles include:
– Amplitude & Frequency: Optimized for material type (e.g., 3–5mm amplitude for coarse aggregates).
– Deck Configuration: Single/multi-layer decks (e.g., 2–4 layers) adapt to gradation requirements.
– Screen Mesh Material: High-carbon steel or polyurethane for durability (lifespan: 6–24 months).

Core Equipment in Aggregate Processing Lines

A typical sand-making line integrates:
1. Primary Crusher: Jaw crusher (Feed size: ≤1200mm, Capacity: 50–1500t/h).
2. Secondary Crusher: Cone crusher or impact crusher (Output: 0–40mm).
3. Vibrating Screen: Multi-deck design (e.g., Model XYZ-2460, Capacity: 200t/h, Power: 15kW).

Equipment Key Parameters
Jaw Crusher Feed opening: 600x900mm, Motor: 75kW
Cone Crusher Closed-side setting: 10–50mm, Throughput: 150t/h
Vibrating Screen Deck size: 2400x6000mm, Mesh aperture: 5–100mm

FAQ

Q1: How to reduce screen clogging?
A: Use polyurethane meshes or ultrasonic cleaning systems.

Q2: What’s the optimal inclination angle?
A: Typically 15°–25° for dry screening; adjust based on material flow.

Engineering Case Study

Project: Limestone crushing plant in Malaysia.
Solution: Deployed a 3-stage crushing line with a vibrating screen (Model XYZ-2460) achieving 95% screening efficiency. Output: 500t/h of high-quality aggregates for concrete production.
