As I understood it from using controlled droplet application of herbicide 
40 years ago the attribute of the spinning toothed disc was to form 
droplets of a uniform size. Nozzles tend to produce a wide range of sizes 
and the smallest are to be avoided because they drift too far.

The liquid is fed at a controlled rate onto the disc where is is driven 
out to the periphery by the spinning and finally reaches the tooth. A 
droplet begins to form but the liquid remains adhered to the tooth until 
enough liquid builds up to form a droplet. The droplet breaks away from 
the tooth when the centrifugal force becomes greater than the adhesive 
force and this is a function of the rate of spinning.
