Vibrating Screen
Vibrating Screen
Vibrating screens are widely used for grading and screening materials in such fields as chemical industry, minerals, quarry, building materials, water conservancy and hydropower, transportation, smelting and so on. Vibrating screens are efficient screening machines for the classification of bulk material such as coal, minerals, coke etc. There are 40 specifications for this series vibrating screen, of which the heavy duty type of vibrating screens are for the classification of large size materials, while the light duty type of vibrating screens are for the middle and small size materials.

3. Both feed port and discharge port are adjustable, easy to control output.
4. Energy efficiency, low production cost, long service life, eco-friendly.
Vibrating screen moves round. It has multi-layers and is of high efficiency. The eccentric shaft vibration exciter and partial block help to adjust amplitude. The material drops down along the long line. In screen grading, the material is separated mechanically on screen plates. Rolling bearings in vibrating screens are stressed by high, mostly shock-type loads. Moreover, the bearings, while rotating about their own axis, perform a circular, elliptical or linear vibrating motion. This results in high radial accelerations which additionally stress the bearings, and especially the cages, considerably. The operating speeds are usually very high. As a result, the bearing temperatures are up to 20 to 30 degrees Kelvin higher than in normal applications. In addition, considerable misalignments between the bearing locations and considerable shaft deflections have to be accommodated.
