I. Basic Definition
A vibrating sand and gravel separator is an environmentally friendly device that uses a high-frequency vibrating screen to efficiently separate and recycle gravel, sand, and slurry from a sand and gravel mixture (especially waste concrete). It is commonly used in mixing plants and sand and gravel yards.
II. Working Principle
1. Vibration and Dispersion: A vibrating motor/exciter drives the screen box to vibrate at high frequency, breaking up clumps of concrete and disrupting the adhesion of sand and gravel.
2. Screening and Grading:
◦ Large-diameter gravel → Upper large-pore screen → Gravel outlet
◦ Sand → Lower small-pore screen → Sand outlet
◦ Slurry and water → Pass through the screen → Slurry tank
3. Cleaning and Recycling: High-pressure water jet cleaning is used in conjunction with the separation process. The separated sand and gravel can be directly reused, while the slurry is recycled after sedimentation/pressure filtration.
III. Core Structure
• Screen Box: Main body, box-type welded, high strength and wear-resistant
• Vibration System: Dual motors/vibrator, linear/compound rotary vibration
• Screen Mesh: Multi-layer (usually 2-3 layers), polyurethane/high manganese steel material
• Cleaning System: High-pressure water pump, spray pipes
• Electrical Control System: PLC automatic control
• Vibration Damping Springs: Noise reduction and machine stability
IV. Main Features
• High Efficiency: Separation rate 90%-95%, processing capacity 15-50t/h
• High Precision: Multi-layer screen mesh, clear grading
• Anti-clogging: High-frequency vibration prevents screen clogging
• Energy and Water Saving: Low power consumption, water circulation
• Compact Structure: Small footprint, easy to install
• Durable: Wear-resistant screen mesh, IP65 motor
V. Application Scenarios
• Concrete mixing plant (cleaning of tanker waste)
• Sand and gravel yard, manufactured sand grading
• Recycling of construction waste aggregates
• River dredging, mine tailings treatment
Would you like me to compare vibrating and drum sand separators to help you determine which is more suitable for your working conditions
