Square vibrating screen is a screening equipment based on the principle of planar rotary vibration. Its box is a square structure, consisting of four core components: screen frame, vibration motor, shock-absorbing spring, and screen mesh. Compared with traditional circular vibrating screens, the square design makes the material distribution more uniform, making it particularly suitable for high-precision grading scenarios. The vibration motor generates a three-dimensional motion trajectory with an installation angle of 15-25 °, which not only achieves forward material conveying, but also enhances the screening rate through vertical throwing. The typical vibration frequency is 960-1500r/min, with an adjustable amplitude range of 2-8mm, suitable for the separation needs of materials with different particle sizes.
Performance advantages of square vibrating screen
•Multi layer screening capability
Up to 5 layers of screen mesh can be stacked (commonly made of 304 stainless steel or polyurethane material), with a grading accuracy of 0.025-50mm and a processing capacity 20% higher than circular screens of the same size. For example, the QS-800 equipment can process 3 tons of quartz sand per hour and complete three levels of classification: coarse, medium, and fine.
•modular design
The quick release screen replacement only takes 5 minutes, and the sealing structure adopts a dual dust-proof design of silicone and flange, which meets the pharmaceutical grade requirements of GMP standards.
•intelligent control
The new equipment is equipped with a frequency converter to adjust the vibration intensity, and real-time monitoring of screen breakage through acceleration sensors to avoid material leakage.
Square vibrating screen industry application
In the field of chemical engineering, square vibrating screens are used for catalyst carrier classification, and corrosion-resistant titanium alloy mesh screens should be selected; The food industry focuses on hygiene design and is often equipped with CIP cleaning interfaces.
