More Information
Summary:The effects of guar gum and xanthan gum as stabilizing additives on the sedimentation stability, plastic viscosity and yield value were compared to prepare slurrres with different coal particle size distributions. The coal particle size distribution was essential factor for the preparation of CWS and both gums were effectively used in broad particle size distribution slurries as stabilizing agents.
