The coarse solids travel down the sides and can be removed from the bottom. Fine particles are separated by over flow. Bottom product tank is provided with the setup. EXPERIMENTATION :- To determine the separation efficiency of given Classifier. To determine the effect of velocity on separation efficiency.
