Method of producing dry granular fertilizer and soil amendments using clay slurry and dry chemicals

摘要

An improved continuous process for producing granular fertilizer and/or soil amendments resulting in a high quality granular product. A slurry of clay in water with a dispersant is prepared using intensive mixing. Dry components are intimately mixed with the slurry in a mixer. The mixture is fed into a granulator to produce granules within a desired range of granule sizes. The granules are dried in a dryer and screened to remove any granules of an undesired size. The undesired granules are recycled.
