Water dispersible granules share many of the same advantages and disadvantages of wettable powders except they are more easily measured and mixed, because of low dust they cause less inhalation hazard to the applicator during handling.

Water dispersible granules can be made by several techniques.

The most common include extrusion to produce cylindrical pellets.

Another one is pan granulation, tumbling in a pan basically to produce spherical balls.

This is done by spraying a liquid, usually water, onto the tumbling powder to cause agglomeration by the snowball effect.

Another technique is the compaction.

In this process a powder with an included binder is compressed into a small sphere, disc or obloid.

Tablets may be considered to be a form of disc-shaped compacted granule.
