A rotary atomizer suitable for spraying crops with liquid in the shape of a hollow truncated cone having a toothed periphery and internal radial grooves has asymmetric teeth, one side of each tooth being radial and the other side of each tooth being disposed at an angle, preferably 30°-60° to the radius. The grooves lead to the gaps between teeth and may be similarly assymmetrical. n The atomizer is unidirectional being rotated so that the radial teeth edges are the leading edges. It may be used singly, or as a stack of cones. |
