Vibrating Screen
Introduction
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. It is widely used for grading and screening materials in the following fields: minerals, quarry, building materials, water conservancy and hydropower, transportation, chemical industry, 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 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.
Vibrating screen Working Feature
1. Before starting, we should inspect every fasteners bolt of vibrating screen whether to become less crowded, if it has, we should fasten it one time.
2. After the sieve machine has empty motion for 4-6 hours, the sieve body should be steady. No sway and unusual sound and driver bearing temperature≤7512.
3. After idle operation movement, we should examine every spots spiral of vibrating screen fastens one time.
4. In normal work, it should have periodic inspection of every fasteners bolt tight situation.
5. Inspect vulnerable, the use and the maintenance frequently, please refer to the instruction for use. (vibrating motor should be refueled one time after 3 months, driver be refueled one time every month, a minor repair half year, a overhaul one year.)
6. Before parking, you should stop giving the material first and waiting for the screening surface material to walk.
7. When the vibrating screen working, you should observed the sieve machine operational aspect continuously, if there are not normal movements or unusual sound about the vibrating screen, should shutdown the machine and check, discover the reason then remove difficulty.
Vibrating Screen Advantages
1. This series of vibrating screens use 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 our vibrating screens 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. SBM's vibrating screens adopt 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.
