ABSTRACT:
A method and an apparatus for treating a gravel type solid material with a liquid in a bath are described. The apparatus comprises means for supplying the solid material, means for transporting it through the bath and means for removing the processed solid material from the bath. The apparatus comprises further means for supply of liquid and tapping off of the liquor. The method comprises introduction of the gravel type solid material into the bath at its lower end and removal of the processed solid material at the upper end, the gravel type solid material being gradually transported upwards through the bath by means of rotating lifting members while liquid is introduced into the bath at its upper half while liquor is drained off at the lower half. The lifting member comprises at least one inclined plate which is rigidly fixed to a vertical tube through which the solid material is introduced into the bath or the tank.
