ABSTRACT:
Small particles and fines included along with larger subdivided solids are treated with liquid to extract soluble solids therein in an apparatus and process using milli-screens with milli-sized openings of less than about 0.095 inches across. The milli-screen openings may be kept open for the passage of liquids with specially-designed wipers and/or back-flushing from a liquid compartment and/or rotation of the milli-screen past the matrix of subdivided solids, the subdivided solids themselves acting as a screen cleaner. The invention is useful in batch or continuous diffusers for extracting soluble solids from subdivided solids containing small particles and fines.
