Abstract (en)

[origin: WO0078907A1] A process for the production of granular detergent compositions is provided wherein fluid bed granulation is employed in conjunction with selected recycle of oversized particles to control the uniformity of the resulting detergent composition. The process comprises feeding starting ingredients into a fluid bed granulator to at least partially granulate the feed material while employing the fluid bed to control undersized particle generation and sizing in conjunction with recycle to control oversized particles.
