Vibrating Screen Description
Shanghai jianye virbrating screen is vibrated by the circling motion, and the amplitudes strength can be adjusted . It has a long screening produce line and has several layers. Each kind of size is sieving separately. It has high screening efficiency, and suitable the screening task of mining and sandstones industry. Vibrating Screen is 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 Screen Working Principle
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 screen 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 of the vibrating screen 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.
