ABSTRACT:
A process for the dewatering of fine granular material is disclosed. During compression of the material, fluid is expressed and a small percentage of the material is intentionally permitted to escape through a self-cleaning opening in the apparatus. By maintaining the smallest dimension of the opening in the range of one to five times the diameter of the largest particle in the material, the opening remain essentially clear of any material which could cause plugging.
