摘要：
A granular detergent product is made by spraying a liquid binder to contact a particulate solid starting material in a low shear granulator such as a fluidized bed apparatus. The d3,2 average droplet diameter of the liquid binder is not greater than ten times the d3,2 average particle diameter of that fraction of the solid starting material which has a d3,2 particle diameter of from 20 &mgr;m to 200 &mgr;m provided that if more than 90% by weight of the solid starting material has a d3,2 average particle diameter less than 20 &mgr;m then the d3,2 average particle diameter of the total solid starting materials shall be taken to be 20 &mgr;m. If more than 90% by weight of the solid starting material has a d3,2 average particle diameter greater than 200 &mgr;m than the d3,2 average particle diameter of the total starting solid material shall be taken to be 200 &mgr;m.
