CoalPro Column Flotation Cells are ideal for efficient recovery of fine coal (0.2 mm) particles. The high-capacity columns with low operating and maintenance costs feature Slam-Jet spargers for greater plant yield. The CoalPro column flotation cell offers several novel design features that are critical for fine coal flotation, including: Multi-point feed distribution, internal product launders, and a removable self-closing air sparging system (Slam-Jet). The SlamJet uses a removable, single-orifice nozzle with high-velocity air injection to create finely dispersed bubbles in the flotation column. Considered a breakthrough in column sparging technology, the SlamJet design has been accepted internationally and has eliminated a variety of maintenance problems. There are more than 60 CoalPro installations in the United States.
