Vibrating Screen Overview
vibrating screenVibrating screen is the circular vibrating type; we also called it Circular Vibrating Screen. It earns this name by reason of its approximately circular movement. The vibrating screen is a kind of sieving equipment of international advanced level, developed by our company on the basis of carrying on the advantages of traditional screens and absorbing the outstanding technology from abroad. Vibrating Screen is of multilayer and high efficient. The eccentric shaft vibration exciter and partial block help to adjust amplitude. This kind of Vibrating screen is of long streamline, clear screening for different specifications.
Vibrating Screen Parts
Vibrating screen mainly consists of screen, transmission part and main unit including screen box,supported device and exciter.
Vibrating Screen Application
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 Main Features and Benefits
  1. This series of vibrating screen uses eccentric block to produce strong exciting force.
  2. Crossbeam and the main body of the vibrating screen are connected with high strength screw bolts. So they have the features of simple structure and easy maintenance.
  3. The vibrating screen adopts tire coupling with capability of flexible connection and stable operation.
  4. It adopts the structure of small amplitude, high frequency, large obliquity to make the screen hold the capability of high efficiency, large handling capacity, long life span, low consumption, and little noise; you will find this series of vibrating screen optimized for your demands.
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.
Vibrating Screen Operation
  1. The operator on duty should read records, and conduct general inspection of vibrating screen equipment before work. Check tensioning extent of the V-belt, the oil level of vibrator, check the vibrating screen surface tension situation.
  2. The vibrating screen should be stared followed the order of process system.
  3. When working, use visual, hearing tests and screening exciter boxes work. After stopping touch the bearing caps and check bearing temperature rise situation.
  4. The vibrating screen should be stopped followed the order of process system. Except special requirements, prohibite to continue to sieve after stoping.
  5. When shift relief, put down the state technology of the vibrating screen and discovery to duty records.
