    While solid bowl centrifuge technology has been around the coal industry since the 1970s, no one could make the technology work well enough to be economically viable.

    While solid bowl centrifuge technology has been around the coal industry since the 1970s, no one could make the technology work well enough to be economically viable.

      The resulting coal product was too high in moisture, so the coal industry rejected the technology. However, Somerset Coal International cracked the code with Sub325® fine coal recovery technology—enabling minus 325 mesh (44µm) particles to be delivered to the clean coal belt consistently at moistures between 15 and 23%.

      Cracking the Code

      Somerset partnered with one of the world’s leading centrifuge manufacturers, Centrisys Corporation, a proven leader in centrifuge technology who shared our vision for innovation and made three key improvements to the solid bowl centrifuge technology:

      1
        The internal geometries of the decanter centrifuge have been redesigned, allowing the delivery of previously unobtainable low moisture ultra-fine coal particles.
        2
          Through a variation of process control, the optimum G-force and torque are achieved to create optimal particle-water separation.
          3
            The rotational differential between the bowl and the scroll of the centrifuge has been optimized through a wider range of variable options.

            These three key improvements allow the Sub325® system to significantly decrease the moisture in the resulting product. As a result, you can now realize higher plant yield and a new revenue stream!

            ABOUT THE SUB325® SYSTEM

            • Uses powerful solid bowl centrifuge technology that separates the clean coal from the water
               
            • Uses programmable logic controller (PLC) to continuously monitor input into the unit, make adjustments and provide critical operational data based on a custom program
               
            • Uses hydraulic variable speed drive to control the speed of the machinery, ensuring maximum results, maximum centrifugal force and ideal water-particle separation
               
            • Seamlessly integrates into your operation with no downtime—“tie-in” time is all that is needed
