The vibrating screens used for stone crushing and screening can be mainly classified in the following ways:
1. Classification by motion trajectory
Circular vibrating screen: It uses an eccentric block as the excitation force and performs circular motion. It has a high screening efficiency and is more suitable for screening sand and gravel in large quarries. It can also be used in coal selection, mineral processing, electricity, chemical and other industries.
Linear vibrating screen: The motion trajectory is a straight line. The screening efficiency is slightly lower than that of the circular vibrating screen, but it is more suitable for small-scale mining or screening of finer materials. It is widely used in coal, metallurgy, light industry and other industries.
2. Classification by purpose and screening material
Heavy vibrating screen: It is generally used to screen ore and is used together with a crusher. It is suitable for stone crushing and screening scenarios.
Other specific purpose vibrating screens: Rotary vibrating screen: A vibrating separator used to separate powders, particles and liquid slurries. It has high screening accuracy and can reach 500 mesh. It is suitable for screening fine materials, such as powder coatings, pigments, cosmetics and other industries24.
Drum screen: The main structure is a screening drum, which is composed of several circular screens. It is suitable for scenes that require uninterrupted cleaning of the screen body. 2.
Swing screen: It imitates the manual screening action. The rotation of the eccentric block causes the screen body to swing. The material stays on the screen surface for a long time, and the screening effect is fine. It is suitable for scenes with high requirements for screening effect. 4.
In addition, there are many types of vibrating screens, such as fixed screens, drum screens, equal thickness screens, roller screens, resonance screens, probability screens, high-frequency vibrating screens, and electromagnetic vibrating screens, but these may not be the types commonly used in stone crushing and screening. 5.
In summary, there are various ways to classify vibrating screens for stone crushing and screening. The specific type of vibrating screen to be selected needs to be determined according to actual production needs and material characteristics.
