Circular Vibrating Sieve Equipment for Gravel

It is efficient screening machines for the classification of bulk material such as coal, minerals, coke and more

It is designed for especially screening stone stock of quarry and also for classifying and screening products of such departments as coal separator, mineral processing, building materials, electricity and chemical industry, cement production line, water conservancy and hydropower, transportation, smelting and etc.

 

Working principles:

The barrel-type vibration exciter is installed in the middle part of the machine.During normal operating, the vibration of exciter will drive the screen mesh fixed on the screen box vibrate and then materials will be screened.The big and small materials fall from the upper side and lower side of the screen to get them separated 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 misalignment between the bearing locations and considerable shaft deflections have to be accommodated.
