Vibrating screen manufacturing involves the production of mechanical equipment designed to classify or separate solid materials based on size, density, or shape. It operates using vibration motors, eccentric weights, or electromagnetic systems. The manufacturing process includes critical engineering stages such as vibration mechanism design, screen mesh selection, and durable frame construction.
Working Principle:
Material is fed onto the screen surface. Vibrational motion (circular, linear, or elliptical) propels the material forward, allowing fine particles to pass through the mesh openings. Oversized particles exit from the top, while undersized particles are discharged from the bottom. Vibration frequency and amplitude can be adjusted according to material properties.
Components:
Screen Mesh: Perforated surface made of stainless steel, polyurethane, or rubber.
Vibration Mechanism: Eccentric shafts, vibratory motors, or electromagnetic exciters.
Frame: High-strength steel structure.
Springs/Damping Systems: Isolate vibrations to prolong machine life.
Applications:
Mining: Size classification of ores, coal, and aggregates.
Construction: Screening sand, gravel, and concrete materials.
Recycling: Sorting plastic, metal, and demolition waste.
Chemical & Food: Powder and granule sieving.
Advantages:
High capacity and efficiency.
Compact design and low maintenance.
Custom designs for wet or sticky materials.
Types:
Circular Motion Screens: Ideal for uniform material distribution.
Linear Motion Screens: Suitable for long material travel paths.
Multi-Deck Screens: Classify multiple particle sizes simultaneously.
Manufacturing Process:
Design: Screen size, deck layers, and vibration type are determined based on material properties.
Material Selection: Wear-resistant steel, polyurethane, or rubber.
Welding & Assembly: Frame and vibration mechanism integration.
Testing & Calibration: Vibration frequency and screening efficiency are validated.
