Circular Motion Screens are operated either by a single shaft vibrator or by a single unbalance motor. Due to the eccentricity of the shaft in the case of single shaft drive, a controlled circular motion is produced. In the case of a single unbalance motor drive, the circular motion is produced by the unbalanced weights on the rotor shaft. These screens have a slope varying between 15 and 25. They are commonly used with a combination of
low amplitude of vibration and high frequency.
Dewatering Screens are used for separation of solids from liquids. Best results are achieved with screens which are slightly inclined so that the mass of solids can accumulate and build up. An adjustable discharge plate allows for fine-turning a high frequency of vibration increases efficiency of sizing and dewatering.
