Characterization of the Vortex Beam by Fermat's Spiral
In this paper, we characterize the helical beam structure through an analysis of the spiral character of the phase distribution inside a light beam. In particular, we show that a line connected with the 2π phase jump in the Laguerre–Gauss beam can be described by a Fermat's spiral. We propose a numerical fitting method to determine the …

Classification
Example 13.1. A slurry containing 50% solids (quartz) is to be classified at a rate of 100 t/h at a separation size of 250 μm in a rake classifier. The density of the solids is 2650 kg/m 3 and the size analysis is given in the table below. The water recovery to the overflow is 95% at an areal efficiency of 0.5.

Vortex Engineering
Grit classifiers are designed to separate grit from the water and transport it to the discharge point. The grit-water mixture is pumped from the grit chambers into the decantation tank of the grit classifier. The grit slowly settles as it has higher density than the water itself. The inclined rotating shaftless screw slowly conveys the settled ...
