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.
