Abstract
A process of forming a granular detergent products, is effected in a gas fluidisation granulator. A fluidised particulate solid material is contacted with a spray of liquid binder. The excess velocity (U.sub.e) of fluidisation gas relative to the mass or volume flux of the spray (q.sub.mliq or q.sub.vliq) when determined at the normalised nozzle-to-bed distance (D.sub.0) is set so that the flux number (FN.sub.m or FN.sub.v) as determined by ##EQU1## (where .rho..sub.p is the particle density) is at a critical value of at least 2 for at least 30% of the process.
