ABSTRACT:
The invention relates to a process for the preparation of water-dispersible granules which comprises mixing the desired ingredients of the granules to form an extrudable composition, extruding the mixture, and rolling the extrusions to break them down into granules. The process of the invention is particularly suitable for the preparation of water-dispersible granules comprising agricultural chemicals (also known as dry flowables) as the process enables high production rates to be achieved and the products have high suspensibility and rapid dispersion.
