The main classification vibrating screen

Author: Time:2018-08-02
Vibrating screen is mainly divided into linear vibrating screen, circular vibrating screen, high frequency vibrating screen. Vibrating screen according to the type of vibrator can be divided into single axis vibrating screen and biaxial vibrating screen. According to the structure and working principle of roughly screening machinery has the following categories:
 

1 plane motion screen, the body is a plane swing or vibration. According to the plane motion trajectory, it is divided into linear motion, circular motion, elliptical motion and complex motion. Shaking sieve and vibrating screen belong to this category.

2. The cylindrical sieve, work part is cylindrical, the screen around the cylinder axis, axis in general downloading into small angle. Material from one end of the cylinder to enter, the level of fine material from the cylinder shape through the pores of the surface of the work, the coarse material from the other end of the cylinder exhaust. The rotating speed of the drum screen is very low, the work is stable and the power balance is good. But the pore blockage, low screening efficiency, small working area, low productivity. Concentrator rarely used it to make screening equipment.

3. Roller screen, the working face is by transversely arranged a root rolling shafts, wherein, the shaft dishes and fine material is from the gap between the roller and plate through. Bulk materials by rollers with trends and from the end of the discharge end of the mobile. Concentrator is rarely used this sieve.

4 fixed screen, the working part of the fixed, by the material along the working surface sliding and the material to be screened. Fixed grid is a kind of application in concentrator, generally used for rough or broken before the pre screening. The structure is simple and the manufacture is convenient. No power, can be directly discharged to the ore sieve. The main disadvantage is low productivity, low screening efficiency, generally only 50-60% .
