Abstract
Process for granulating chemical products, according to which process, recycled granules are conveyed to a rotary drum through an end thereof and are lifted by blades protruding from the drum inner surface, thus falling onto an inner fixed structure, which cause the forming of a vertical curtain of granules, onto which curtain a solution containing the product to be granulated is sprayed; the product solidifies on the granules, which granules, after subsequent falls, are coated with a plurality of layers of solid product before leaving the drum through the other end. The process is characterized in that said inner fixed structure is conveying the falling granules in at least two vertical curtains parallel to each other and to the drum axis, while a portion of the granules, on the side of the downward movement of the drum, directly falls, without passing through a vertical curtain, onto a fixed baffle, which is arranged substantially in the lower half of the drum, on the side of the downward movement.
