Screening Machine--Vibrating Screen
vibrating screen is vibrated by the circling motion. The screen line of material is long and the screening specification is various. The screen of very specification is clear. It adopts the tubbish vibrator and eccentric adjustment, with the feature of strong vibration, high screening efficiency and small vibrating noise. This machine is durable, easy to maintain, safe to use. So it is widely used in mining, construction material, transportation, energy and chemical industry for classification.
Vibrating Screen Features:
1)Simple and dependable Eccentric type system.
2)High screening capacity.
3)High durability.
4)No transmission of screen panels.
5)Ready changing of screen plates.
6)Rigid and vibrating resistance screen body.
Illustration of How our circular vibrating screen operates
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.
