    • Drying of coal fines assisted by ceramic sorbents 

      Van Rensburg, M.J.; Le Roux, M.; Campbell, Q.P. (Springer, 2016)
      It is proposed to introduce contact sorption drying as a method to reduce the moisture content in coal fines. The aim of this study was to investigate the possibility of drying fine and ultra-fine coal using porous ceramic ...
    • Drying of fine coal using warm air in a dense medium fluidised bed 

      Van Rensburg, Martha Johanna (2014)
      Fluidised bed drying is currently receiving much attention as a dewatering option after the beneficiation of fine coal (defined in this study as between 1mm and 2mm particles). The aim of this study was to investigate the ...
    • Effect of product bed height and air velocity on the drying rate of extruded maize pellets 

      Pasch, Gerhardus Bartholomeus (North-West University (South Africa) , Potchefstroom Campus, 2015)
      In the food processing industry, specifically food drying and cooling, there is still a lack of available information that is based on experiments and reliable data. A specific product that has not been investigated is ...
    • Fine coal dewatering using high airflow 

      Le Roux, M.; Campbell, Q.P.; Van Rensburg, M.J. (Taylor & Francis, 2014)
      Fluidized bed drying is currently receiving much attention as a dewatering option after the beneficiation of fine coal. Apart from concerns about safety and combustion, the operating costs can be high if very high gas or ...
    • A review of the application of X-ray computed tomography to the study of coal 

      Mathews, Jonathan P.; Campbell, Quentin P.; Xu, Hao; Halleck, Phillip (Elsevier, 2017)
      There has been a long history of using X-rays to visualize coal and its transitions during various treatments. Advances and improved availability has allowed the application of X-ray computed tomography (CT) to create 3D ...
