A linear vibrating screen is a widely used screening machine in the mining industry for separating and classifying bulk materials such as ores, coal, gravel, and sand. It operates by generating linear motion to efficiently screen materials based on particle size.
Key Features of Linear Vibrating Screens for Mining
1. High Efficiency & Large Capacity
– Uses dual vibrating motors to generate strong linear vibration, ensuring high screening efficiency.
– Suitable for large-scale mining operations with heavy-duty processing needs.
2. Durable Construction
– Made from high-strength steel or wear-resistant materials to withstand harsh mining conditions.
– Reinforced screen decks for long service life.
3. Multi-Layer Screening
– Available in single or multiple decks (2-4 layers) to classify materials into different sizes simultaneously.
4. Adjustable Amplitude & Frequency
– Allows optimization of screening performance for different materials (e.g., fine powders vs. coarse ores).
5. Low Maintenance & Easy Operation
– Simple structure with minimal moving parts reduces downtime.
– Sealed bearings and dust-proof design enhance reliability.
6. Wide Range of Applications
– Used in coal, iron ore, gold, copper, limestone, and other mineral processing plants.
– Also suitable for quarrying and aggregate industries.
Working Principle
– The screen is driven by two synchronized vibrators (motors or exciters) that create a linear reciprocating motion.
– Material is fed onto the screen surface and moves forward in a straight line due to vibration.
– Smaller particles pass through the screen mesh, while larger particles are discharged from the end.
