Abstract
A centrifugal type counterflow contact apparatus having a rotary body or drum intergrally mounted on a rotary shaft, and a plurality of ring members disposed within the rotary body such that circumferential slits are defined between the adjacent ring members in the axial direction of the rotary drum. The ring members have a cross sectional configuration inclined with respect to the axis of the rotary body. A light liquid is introduced into the periphery of the rotary body while a heavy liquid is introduced in the center portion of the rotary body. The heavy and light liquids flow countercurrently through the slits between the ring members under the centrifugal force produced by the rotation of the rotary body, whereby extractability can be improved and accumulation of solids entrained in the feed can be avoided.
