A vibrating screen for stone is a mechanical equipment used to separate and classify different sizes of crushed stone, gravel, or other aggregates in mining, quarrying, and construction industries. It works by vibrating the screen mesh to allow smaller particles to pass through while larger stones are retained.
Key Features of a Stone Vibrating Screen:
1. Screen Deck: Single or multi-layered screens (usually 1-4 decks) with different mesh sizes.
2. Vibration Mechanism:
– Circular Motion Screens – Common for general screening.
– Linear Motion Screens – Ideal for fine screening or sticky materials.
– Elliptical Motion Screens – Used for high-capacity applications.
3. Drive System: Electric motor with vibrators (unbalanced weights or exciters).
4. Screen Mesh Material: High-carbon steel, stainless steel, or polyurethane for durability.
5. Frame Structure: Heavy-duty steel frame resistant to wear and impact.
Applications:
– Crushed stone grading (e.g., 0-5mm, 5-10mm, 10-20mm).
– Gravel separation in sand and gravel plants.
– Recycling construction waste (concrete debris).
– Mining ore classification.
Types of Vibrating Screens Used for Stone:
1. Circular Vibrating Screen – Best for medium-fine screening.
2. Linear Vibrating Screen – Suitable for dry/wet screening with high efficiency.
3. High-Frequency Screen – For fine particles (<3mm).
4. Trommel Screen – Rotating drum screen ideal for wet/sticky materials.
Selection Considerations:
– Required throughput (tons/hour).
– Particle size distribution needed after screening.
– Moisture content (dry vs. wet screening).
– Space constraints and installation setup.
