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.
