Recently, I have received a lot of questions about vibrating screens and dewatering screens. Do many people want to know what is the difference between these two products? Today, the editor of Luoyang Longzhong Heavy Industry will give you a detailed answer to this question.
The working principle and structure of the dewatering screen and the vibrating screen are similar, but there are also differences. The dewatering effect of the dewatering screen is remarkable, and it is suitable for the dewatering of materials with large moisture content. The vibration intensity of the vibrating screen is large, the screening effect is obvious, but the dehydration effect is relatively weak, and it is more suitable for the screening and classification of materials with low water content. The two types of equipment have their own strengths, and users can choose according to the actual situation of their own materials and the functions they want to achieve.
Vibrating screens and dewatering screens are both types of screening equipment, but there is a big difference between the two.
1. The principle is different
The vibrating screen works by using the reciprocating rotary vibration generated by the vibrator excitation. The upper rotating weight of the vibrator causes the screen surface to generate plane whirling vibration, while the lower rotating weight causes the screen surface to generate conical surface rotation vibration.
The dewatering screen adopts dual-motor self-synchronization technology, a universal eccentric block, and an adjustable amplitude vibrator. It is mainly composed of a screen box, vibration exciter, support system, and motor. The two unconnected vibrators are driven by the belt coupling for synchronous and reverse operation. The centrifugal force generated by the two groups of eccentric masses is superimposed along the vibration direction, and the reverse centrifugal force is offset, thereby forming a single excitation vibration along the vibration direction. , so that the screen box does a reciprocating linear motion.
2. Different materials
The general vibrating screen is to classify and screen materials with different particle sizes, including dry screening and wet screening. The proportion of materials on and off the screen depends on the material itself.
The dewatering screen is to dry the materials in the cement slurry to realize the separation of slag and water and achieve the purpose of dry stacking or transportation. Generally, the more materials on the screen are required to be discharged dry, the better.
3. Different advantages and disadvantages
Advantages and disadvantages of vibrating screen: lightweight, high efficiency, complete and diverse series, and multiple layers, which can meet the needs of dry material screening. This model is not suitable for materials with high moisture content and adhesion.
Advantages and disadvantages of dewatering screen: It can be customized according to the output and water content, the screen hole can be adjusted according to the needs, the dewatering effect is good, the equipment noise is low, and it is suitable for products with low mud content. The product is larger in size.
4. Different sieve surface forms
The vibrating screen is a horizontal or downward screen surface to facilitate discharge.
The screen surface of the dewatering screen is mostly upward climbing, which is conducive to dry discharge.
5. Different scope of use
Dewatering screens are generally used in conjunction with sand washing machines and are often used in wet sand production lines. The machine-made sand production line is equipped with a sand washing machine, and the mud powder in the sand is removed by the washing of the sand washing machine. However, after the general material is washed by the sand washing machine, the water content of the material is large, and it needs to be dewatered through a dewatering screen. , De-intermediation, de-sliming, and reducing the mud content to less than 0.7%, to meet the standard of construction sand.
The scope of application of vibrating screens is very wide, and various types of vibrating screens are required in processing and manufacturing. Vibrating screens are generally used in conjunction with feeders and crushers and are often used in dry sand production lines.
The above is all about the difference between a vibrating screen and a dewatering screen. If you want to know more about sand washing equipment, you can visit the website of Luoyang Longzhong Heavy Industry or call for a consultation at any time.
