Circular Vibrating Screen | XingQing Machinery

Product OverviewProduct Overview

The YK Series Circular Vibrating Screen is a high-efficiency multi-layer screening equipment independently developed by XingQing Machinery. It uses a cylindrical exciter and eccentric shaft structure. Material moves along a circular arc trajectory on the screen surface, with long screening flow lines, multiple screening specs, and clear product size classification. The series covers 2YK to 3YK with 30 specification models, screen areas from 6m² to 64.8m², capacity from 8 to 800 t/h, meeting capacity requirements from small-medium to large mines. The entire series comes standard with an adjustable excitation force system, adapting to different material characteristics and screening accuracy requirements.

Working PrincipleWorking Principle

1

Excitation Drive

The motor drives the eccentric shaft to rotate at high speed through a belt. The cylindrical exciter generates centrifugal force, causing the screen box to vibrate along a circular arc trajectory.

2

Material Entry

Material evenly falls from the feed opening onto the screen surface, moving forward in a throwing motion under vibration force.

3

Layered Screening

Multi-layer screens screen from top to bottom progressively. Coarse particles remain on upper layers, fine particles fall through layer by layer, achieving multi-stage particle size separation.

4

Product Discharge

Oversize and undersize products at each level are discharged from their respective discharge openings, completing the entire screening and classification process.

Process Flow

Motor drive → Eccentric shaft rotation → Exciter generates centrifugal force → Screen box circular vibration → Material throwing and layering → Multi-stage screening → Graded discharge
