China FYS Series Square Swing Screen - High Precision Screening Solution from Trusted Suppliers & Factory
Working Principle
The square swinging screen, also known as reciprocating screen, has high-precision and high-efficiency screening equipment with large output; The transmission mode is artificial, the motion track is forward and left to draw an elliptical trajectory, so that the material is close to the mesh surface, the elliptic curve motion is used above the screen, the vibration force generated by the driving device is a inertia force around the fixed axis, the direction is a certain rule of change, its essence is the reciprocating inertia force formed by the eccentric rotation around the fixed axis. Make the material stay on the screen surface for a long time, so as to achieve effective screening. After the screen machine starts, the screen box moves back and forth under the action of inertial force, the screen box drives the screen surface to periodically shake, so that the material on the screen surface with the screen box to make a plane circular movement, during which, the material less than the screen surface aperture falls to the lower level through the screen hole, becoming the material under the screen surface aperture after continuous tumbling and jumping movement from the discharge port to complete the screening work.
Characteristic and feature of FYS series square swing screen:
- (1). Fully closed structure, dust does not fly, the use of partial balance, so that the screen vibration is small, low noise. Meet environmental protection requirements.
- (2). Combine circular, ellipse and straight line three kinds of motion, good screening effect. Suitable for screening of various materials.
- (3). Equipped with automatic tensioning and automatic cleaning screen installation system, so that the screen utilization rate is high, long life, and the network structure is simple and fast.
- (3). Multi-layer screen frame design for customers to choose.
- (4). Used for the screening and grading of powdered or granular feed, it can also be used for the initial cleaning of raw materials in feed mills, and the grading of intermediate products after secondary grinding in large and medium-sized feed mills.

Frequently Asked Questions
What is a square swing screen?
A square swing screen, also known as a reciprocating screen, is a high-precision, high-efficiency screening machine designed for large output. It replicates manual screening motion to achieve precise material separation.
How does the FYS series square swing screen work?
The machine uses reciprocating inertial force generated by an eccentric drive. This action causes materials to move in a combination of circular, elliptical, and linear motions across the screen surface, ensuring long retention times and efficient screening.
What are the environmental benefits of this equipment?
It features a fully closed structure that prevents dust from escaping into the air. Additionally, it uses a partial balance design, which ensures low vibration and minimal noise during operation to meet environmental standards.
What industries commonly use the FYS series swing screen?
It is widely used for screening and grading powdered or granular feed, initial cleaning of raw materials in feed mills, and grading intermediate products after secondary grinding in large and medium-sized feed mills.
How does the automatic cleaning system benefit the screen?
The integrated automatic tensioning and cleaning system prevents mesh clogging, increases screen utilization, simplifies screen replacements, and extends the overall service life of the screening mesh.
