Comparison between square oscillating screen and
linear vibrating screen in quartz sand screening application
Quartz sand is a quartz particle formed by crushing quartz stone. It is an important industrial mineral raw material and is not a chemical hazardous material. It is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive, filter material and other industries.
For the grading and screening of quartz sand, both square swing screen and linear vibrating screen can screen quartz sand, but the working principles of the two equipment are different. The square vibrating screen is screened by swing, and the linear vibrating screen is screened by vibration. So, in the screening process of quartz sand, which equipment will have a more prominent screening effect? Undoubtedly, the precision and output of the square swing screen will be higher, but in the actual procurement, the selection should also be made according to the customer's requirements, such as output, precision, screening specification, etc. Next, we will explain the square and linear vibrating screens produced by our company
Square swing screen
The square swing screen is a new multi-purpose screening equipment specially designed to meet the screening requirements of large output and high precision. It successfully simulated the effective principle of manual screening movement (screening accuracy, efficiency and screen life are 5-10 times of that of conventional round screen). Due to its structure and working principle, the square swing screen is particularly suitable for screening and processing of granular materials and fine powder materials. Its new design concept and structure make it a screening equipment close to the manual screening operation. It skillfully combines the screen - (plane circular motion) and the bump - (upward parabolic motion). By adjusting the warp and tangential angles, it can change the retention time and movement route of the material on the screen surface to achieve good screening effect.
Linear vibrating screen
Compared with square vibrating screen, the price of linear vibrating screen is much cheaper. The screening requirements can achieve certain results, but for fine specification screening, the square swing screen is still more advantageous. The linear vibrating screen can usually be made into 1-6 layers, and the linear vibrating screen with different layers can be selected according to the specific needs of screening materials. Moreover, the machine has many sizes and specifications, so different models can be selected according to specific production requirements. It can also design and produce linear vibrating screening machines with non-standard size or non-standard discharge and feed openings according to user requirements.
Comparison of advantages and disadvantages between square swing screen and linear screen
Square swing screen linear vibrating screen
Elliptical rocking (simulated artificial) high-speed vibration screening of materials
There is no material that may be damaged
The accuracy can reach 95%, the accuracy 50% - 95% (different materials)
No hammering, relatively less abrasion, less hammering on the screen surface, and more abrasion on the screen
Through the above comparison, we believe that you have a certain understanding of square swing screen and linear vibration screen, so it is unnecessary to select square swing screen for materials with good fluidity, not afraid of crushing, and not strict requirements on output and accuracy, which will increase the operating costs of enterprises. However, if the screening requirements are relatively high, and the accuracy and output need to reach a certain level, then the square swing screen is still very advantageous.
