Flow Visualisation And Velocity Measurements In A Vertical

Oct 01, 2003 The angle of the classifier cone is 70 . The model was designed to simulate only the aerodynamic features of a coal mill, so the grinding bed and related components have not been included. Perspex and polycarbonate sheeting were used to allow full optical access.The higher primary air flow reduces the residence time of coal particles in the mills, reducing the grinding time and thus resulting in coarser coal particle sizes exiting the mill. The results of the coal particle sizes are discussed later. 3.2. Coal Mass Flow Distribution
