Building on the above point, Bennington says the most common way cyclones are used is in tandem with a dewatering screen. "The screen usually has urethane media with 1/4 to 1 mm slots," Bennington says. "You want to put so much material on the screen that the particles that are smaller than the slots get pumped back to the cyclone.
