Title: Ash reduction in clean coal spiral product circuits

Abstract

The article describes the Derrick Corporation's Stack Sizer{trademark} technology for high capacity fine wet cleaning with long-lasting high open-area urethane screen panels. After field trials, a Stack Sizer fitted with a 100-micron urethane panel is currently processing approximately 40 stph of clean coal spiral product having about 20% ash at McCoy-Elkhorn's Bevin Branch coal preparation plant in Kentucky, USA. Product yield is about 32.5 short tons per hour with 10% ash. The material is then fed to screen bowl centrifuges for further processing. At Blue Diamond Coal's Leatherwood preparation plant similar Stacker Sizers are achieving the same results. 2 figs., 3 tabs., 2 photo.
