Circular Vibrating Screen is a device which operates by making use of indirect excitation of a screen mesh. The screen frame is controlled by unbalance masses that further produce circular vibrating motion. This motion is produced with the help of two out of balance weight which are externally fitted. These screens are generally used for screening coal, ore, salt and other bulk materials. Some other applications of Circular Vibrating Screen includes screening of lumpy items for mining industry, waste disposal and pre-screening of heavy duty materials. Also, it is easy to install and handle, light in weight and does not make any noise.
