What are the vibrating screen models?
In mining operations, vibrating screen is one of the screening equipment that is often used. Nowadays, most of the vibrating screens on the market are linear vibrating screens and circular vibrating screens. These two types of vibrating screens can also be divided into various types according to the screening materials, usage scenarios and output. The output corresponding to the model is basically different. Therefore, the understanding of the vibrating screen model can be directly started from the circular vibrating screen and the linear vibrating screen.
1. Circular vibrating screen
The circular vibrating screen, as the name implies, has a circular running track. Therefore, when the material is screened on the circular vibrating screen, it performs circular motion, which is a new type of multi-layer vibrating screen. Circular vibrating screen is often used in quarries to screen sand and gravel materials due to its fast screening speed, high work efficiency, simple structure, reliable operation and low noise, and of course it can also be used in coal preparation, mineral processing and other industries.
YK series is the most commonly used circular vibrating screen at present. The circular vibrating screen of this series is named according to the number of screen layers and screen size, such as 2YK1548. The motion trajectory is similar to a circle, 15 represents the width of the screen, and 48 represents the length of the screen. Therefore, the meaning of this model refers to a two-layer circular vibrating screen with a screen width of 1500mm and a length of 4800mm. Generally, several layers of sieves can produce several kinds of finished products, and the top layer is the return material.
The processing capacity of YK series circular vibrating screen is between 12-720m/h. The larger the model number, the wider the screen width and the longer the length, and the higher the vibrating screen output. The mesh size of the screen can be determined according to the feeding size of the screening material.
Commonly used circular vibrating screen models:
2YK1230, 2-layer screen, the screen area is 7.2㎡, and the processing capacity is 12-78m/h;
3YK1230, 3-layer screen, the screen area is 10.8㎡, and the processing capacity is 13-80m/h;
2YK1237, 2-layer screen, the screen area is 8.88㎡, and the processing capacity is 15-86m/h;
3YK1237, 3-layer screen, the screen area is 13.32㎡, and the processing capacity is 16-90m/h;
2YK1548, 2-layer screen, the screen area is 14.4㎡, and the processing capacity is 22.5-162m/h;
3YK1548, 3-layer screen, the screen area is 21.6㎡, and the processing capacity is 22.5-162m/h;
4YK1548, 4-layer screen, the screen area is 28.8㎡, and the processing capacity is 22.5-162m/h.
2. Linear vibrating screen
The characteristics of the linear vibrating screen are high efficiency, simple structure, convenient maintenance, low power consumption, and no dust spillage during operation. It has good screening effect in dry and wet classification and dehydration of medium and fine materials. Therefore, this type of vibrating screen is widely used in light industry, metallurgy, coal and other industries.
When the linear vibrating screen is working, its power source is the vibration of the vibration motor. Under the combined action of the material’s own gravity and the exciting force, the material is thrown up on the screen surface and moves forward in a straight line, and then is screened out through the screen. Various specifications of materials, different specifications of materials, corresponding to different specifications of the discharge port.
The processing capacity of the linear vibrating screen is generally between 10-600t/h, the feeding particle size is not more than 300mm, the screening particle size is relatively fine, and the maximum screening mesh number is 400 mesh, which can screen out 7 kinds of materials with different particle sizes.
