Principle

The use of horizontal high speed rotating disk giving solution to centrifugal force to throw at high speed, forming a thin film, filament or droplets, due to air friction, obstruction, tearing effect, with the rotation of the disc tangential radial acceleration and centrifugal force generated by the acceleration, velocity results in a fit on the disk, its trajectory is a spiral, with this liquid high spiral since the disc is thrown, it is dispersed into very small droplets the average speed of the disk by cutting along the direction of movement, with the same time and by the droplets fall on the gravity due to spray out particles of different sizes. They thus flying distance is different, so different from the falling particles forming a central symmetry axis of the cylinder.

The requirement to obtain more uniform droplet
a. to reduce the vibration of disc rotation
b. The amount of liquid into the disc remains constant in the unit time
c. the disc surface is smooth
d. circumferential speed of the disc should not be too small, rmin = 60m / s, milk (100-160m / s) if <60m / s, uneven spray droplets

sprayed from the group seems mainly by droplets sink to the plate and near a group of fine droplets of the composition, and decreases with the speed increase
