The large-scale mining circular vibrating screen (also known as mining classification screen, YK series circular vibrating screen) is a high-performance and heavy-duty screening equipment specially designed for the heavy industry sectors such as mining, mineral processing, and sand and gravel aggregates. Its core feature is to utilize the circular vibration trajectory to efficiently classify a large amount of, large-sized, and high-hardness mineral materials. It is an indispensable "key" equipment in modern crushing and screening production lines.
Operating Principle
The screening action is driven by a motor connected via a V-belt to a cylindrical eccentric shaft vibrator. As the motor runs, it rotates the eccentric blocks at high speed, generating substantial centrifugal force. This force is transmitted to the screen box, causing it to oscillate in a near-circular trajectory. Materials fed onto the inclined screen surface are subjected to continuous throwing and spreading motions, allowing finer particles to pass through the mesh openings while coarser material travels toward the discharge end. This controlled, repetitive motion ensures consistent and efficient separation of particles by size.
Key Technical Features & Specifications
Key Technical Features & Specifications
•Adjustable Amplitude: Amplitude can be precisely regulated by adjusting the relative position of the eccentric blocks, allowing optimization for different material types and moisture levels.
•Long Screening Path & High Efficiency: The circular vibration pattern and inclined deck design provide an extended material travel path, increasing the number of contact opportunities between particles and the screen mesh, which enhances screening accuracy and efficiency.
•High Capacity Design: Engineered for heavy-duty operation, the screen can handle feed sizes up to 300–400 mm, with throughput capacities ranging from 10 to 850 metric tons per hour, making it suitable for both primary and secondary screening applications.
•Robust Construction & Configurability:
•Deck Size Range: Available in multiple sizes, with screening decks from 1.2 m x 2.4 m (4 ft x 8 ft) up to 2.4 m x 6.0 m (8 ft x 20 ft), supporting single or multi-deck configurations for producing several product fractions simultaneously.
•Mesh Options: Screen panels are available in various materials to suit specific application needs, including wear-resistant high-manganese steel, corrosion-resistant stainless steel, and noise-reducing, anti-blinding polyurethane.
•Durable & Reliable Operation: The heavy-duty, welded screen body and integrated vibrator assembly are built for continuous operation under demanding conditions, ensuring long service life and minimal maintenance requirements.
This versatile and robust screener is an ideal solution where reliable, high-volume classification of bulk materials is required.
