Metal Powder Size Distribution with the Roller Air Analyzer

Source

Some constructional modifications of the analyzer are described. The apparent size of irregular-shaped particles is quantitatively related to the diameter of sphere separated at the same air velocity. The velocity distribution of the air stream is shown to be linear over a wide range, and the significance is discussed. The size character of the residual particles after a separation is evaluated. Theoretical equations of a size separation are derived and applied to actual separations with several examples.
