Kosun round desilters are designed to efficiently remove silt sized solids (12-74 microns) from plant discharge slurries. Kosun desilters are easier to operate and maintain, making them last more than twice as long as conventional desilters. One of the major advantages of Kosun round desilters is the Kosun 4” hydrocyclone, which are manufactured using a specially formulated EU polyurethane that has excellent resistance to heat and abrasion. Its unique lightweight uni-body construction eliminates excess parts and seams where excessive wear can occur. Kosun manufactures two 4” cones with different internal geometries – with and without a ramp in the feed inlet. The circular pipe feed is smoothly reformed into a rectangular feed. This rectangular ramp feed enters the cone tangentially minimizing turbulence in the upper portion of the cone allowing the solids to quickly move to the wall of the hydrocyclone. The ramp feed cone has a capacity of 80 GPM at 75 feet of head and is primarily used if the cone underflow is over a dewatering screen. Kosun hydrocyclones are available with ceramic inserts for extreme duty. Shut-off valves on each cone inlet permit individual cone removal and inspection without interrupting operation of the desilter. If oversized solids plug the underflow simply unscrew the replaceable wear section (bottom third) clean and replace. Service and replacement of the bottom cone section is made quick and easy by A.N.S.I. buttress threaded bottom sections. The apex is available in two styles: an adjustable tri-nut or fixed snap-on. The desilter is mainly used to eliminate the 20 - 40 micron harmful solids in the mud. The urethane hydrocyclones connect quickly. The Desilter is efficiently designed, easy to maintain and has a long working life with stable performance. Kosun also offers kinds of solid control system, including Desander, Portfire, Decanter Centrifuge, Mud Cleaner, Gas-liquid Separator, Shear Pump, Jet Mud Mixer, Vacuum Degasser, Desilter, Centrifugal Pump, Mud Agitator, Balanced Elliptical Motion Shaker, Screen, Mud Gun, Submersible Slurry pump, Shale Shaker etc.
