Vibrating screen
Application
Vibrating screens are used to separate materials into various sizes for further processing, or for end use, depending on your need. The material is separated by passing it through a vibrating “screen box” which has a number of different sized screens, or meshes, which the material falls through like a sieve. The material falls onto attached conveyors which stocks pile the end products. The end products can then be used in the building and construction industries. Vibrating screen is of reliable structure, strong exiting force, high screening efficiency, low vibrating noise, long durability, convenient maintenance, safe operation, etc. It is widely used for grading and screening materials in the following fields: minerals, quarry, building material, transportation, energy sources, chemical industry, water conservancy and hydropower, smelting etc.
 
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 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 *0 to *0 degrees Kelvin higher than in normal applications. In addition, considerable misalignments between the bearing locations and considerable shaft deflections have to be accommodated.
