Rotary Vibrating Screen

EPIC Rotary Vibrating Screen is a professional manufacturer-supplied solution designed for precise, high-efficiency material screening. As a trusted exporter, EPIC ensures that our product meets the highest international quality standards while delivering robust performance, long service life, and minimal maintenance.

Operating Principle

The EPIC Vibrating Screen operates with a vibrator mounted on the side plate of the screen box, driven by a motor through a V-belt or coupling to generate centrifugal inertia force. This force causes the screen box to vibrate in a circular motion. Material smaller than the screen hole passes through to the lower layer, while larger material is discharged continuously from the outlet.

Key operational guidance:

· Start the machine without material on the screen.

· Feed only after smooth operation.

· Stop feeding before shutting down and clear all material from the screen.

· Regularly inspect for abnormal noise or movement.

Advantages and Features

· Strong Excitation Force: Uses block eccentricity for powerful vibration.

· Durable Structure: Screen box and beams connected with high-strength bolts, no welding required.

· High Screening Efficiency: Small amplitude, high frequency, and large inclination design.

· Low Maintenance: Simple structure ensures easy inspection and repair.

· Energy Saving: Low power consumption with long service life and reduced noise.

· Flexible Operation: Tire coupling ensures smooth, reliable motion.

Applications

EPIC Rotary Vibrating Screen is widely applied in:

· Mining: Gold, copper, iron ore, and other minerals.

· Metallurgy: Screening crushed ores and industrial minerals.

· Stone and Aggregates: Sand, gravel, and crushed stone classification.

· Coal Industry: Sorting raw coal and removing impurities.

· Chemical Industry: Screening powders, granules, and chemical compounds.

Production Process & Quality Control

1. Material Selection: High-quality steel plates and precision components ensure durability.

2. Advanced Manufacturing: Use of CNC machining, automatic welding, and annealing furnaces guarantees accuracy.

3. Vibration Testing: Each unit undergoes rigorous testing for amplitude, frequency, and vibration stability.

4. Final Inspection: Dimensional checks, motor operation, and noise measurement ensure the Vibrating Screen meets international standards.

Comparison

Screen Angle & Performance

The inclination of Rotary Vibrating Screen surface (15–25° for standard models, 20° for large-scale units) directly influences material flow rate and screening efficiency. Adjusting the screen angle allows:

· Faster throughput for coarse material.

· Improved separation for fine particles.

· Reduced clogging and wear on the screen mesh.

FAQ

Q: What is the working principle of the Vibrating Screen? A: Material moves in a circular trajectory under centrifugal force from the vibrator; smaller particles pass through screen openings while larger ones discharge from the outlet.

Q: How does a high-frequency screen differ from a conventional screen? A: High-frequency screens, have smaller amplitude, higher frequency, and optimized inclination, allowing more precise separation and higher capacity.

Q: How should the screen angle be set? A: The screen angle should be adjusted according to material type and particle size to balance throughput and separation efficiency, generally between 15–25° for optimum performance.
