ABSTRACT:
A wet-type rotary sand classifier of this invention is provided with a plurality of helicoid blades which are secured onto the inner surface of the rotary drum along the entire length of the drum with their respective rear ends terminating at the rear end plate of the rotary drum at a desired angle relative to the axis of the rotary drum. Due to the above construction, the sand which has settled onto the inner bottom surface of the rotary drum can be transferred to the rearmost corners formed by the helicoid blades and the rear end plate whereby the thus transferred sand is raised upward by the helicoid blades corresponding to the rotation of the drum without carrying the water dams which are usually formed in the conventional wet-type sand classifier.
