ABSTRACT:
An adjustable vortex finder and kit in a cyclone for adjusting the flow of light fractions from the top outlet of a cyclone comprising a vortex finder, a kit comprising a plurality of sleeve attached by welding with the vortex finder so that each sleeve of the kit may replace any other sleeve. All sleeves of the kit have the same length. The lower edge of each sleeve is even with the top edge of the cyclone dish or is above the top edge of the cyclone by a distance no greater than 0.26B where B is the inner diameter of the cyclone bowl. A collar having an inner opening receives the sleeves of the kit. Each sleeve has a different diameter than the other sleeve in the set of sleeves forming the kit and these diameters vary in dimension between the 0.3B up to 0.5B wherein B is the inner diameter of the cyclone bowl. When it is required to change the sleeve from one diameter to another, the old sleeve is removed from the collar by severing the tack and stitch weld and the new sleeve inserted into the collar by a new tack and stitch weld.
