Square Swing Screen

Core Advantages: Square Structure, Enhanced Efficiency

Guangfeng Sieving's Square Swing Screen takes a large-sized square screen surface as its core design, integrated with a manual-simulating 3D swinging trajectory. Compared with circular swing screens, its effective screening area is increased by over 40%, which enables continuous screening operations for multiple materials with high output. The equipment meets the grading and impurity removal needs of materials with different particle sizes, and it also features high screening accuracy and low material clogging rate, providing an efficient solution for large-scale production.

working principle

From the perspective of the motion trajectory of the shaking body or screening box of the screening machine, the square swinging screen, also known as the arc-shaped screen, generates an inertial force with a certain regularity in direction around a fixed axis due to the vibration force generated by its driving device. Its essence is the reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis. According to the structural characteristics and working principle of the square oscillating vibrating screen, its screen surface is generally arranged horizontally or slightly inclined (with an inclination angle of 0 °~5 °). After the screening machine is started, the shaking body of the screening machine, that is, the screening box, moves back and forth under the action of inertia. The screening box drives the screening surface to shake periodically, so that the material on the screening surface moves in a directional jumping motion together with the screening box. During this process, the material smaller than the aperture of the screening surface falls to the lower layer through the screening hole, becoming the undersized material. The material larger than the aperture of the screening surface is discharged from the discharge port after continuous rolling and jumping motion, thus completing the screening work.

product structure

• The square swing screen is mainly composed of components such as feed inlet, screen box, drive device, screen frame, support frame, vibration reduction device, and discharge outlet.

Feed inlet: The original design attached to the rear door has been changed, and a material distribution plate structure has been added to make material distribution more effective and uniform The weight of the back door has been reduced, making the swinging motion at the feeding end more powerful, allowing the material to be quickly dispersed and screened on the screen surface.
Screening box: includes components such as screening frame, screen mesh, screening grid, spring card, and bouncing ball. The screening frame is equipped with upper and lower layers of screen mesh. The screen mesh is tensioned on the screen grid by spring cards set around the perimeter of the screen grid, and the bouncing ball is set in the grid of the screen grid.
Drive device: includes components such as driver, motor, locking sleeve, locking round nut, stop washer, and cone sleeve. The cone sleeve is fixed on the screen frame, and the drive shaft of the driver is set inside the cone sleeve and connected in place through the locking sleeve.
Universal shaft: The entire screening box is connected by a universal shaft. When the screening machine swings, the universal shaft also rotates, providing a buffering and damping effect on the rotational power, making the entire screening machine run more smoothly.
Discharge port: According to the customer's material screening needs, various designs are made based on different mesh layer requirements. Our design focuses more on facilitating large flow, fast and unobstructed outflow of the screen body, changing various angles, increasing the diameter of the discharge pipeline, reducing the outflow distance and other process methods
