|A column (50 cm 4) provided with a bell charging mechanism and a rectangular perspex insert was used to investigate the inter-relationship between charging pattern, size analysis and velocity profile for a number of charging methods. It is shown that a strong correspondence exists between size distribution and velocity profile for bell charged ore and coke and that decreased coke volumes cause higher pressure drops and increased central flow in beds with "V" shaped layers. It is also shown that a bell charged mixed burden exhibits greater segregation than when it is bell charged as layers and that when uniformly charged the mixed burden shows least segregation and a virtually flat velocity profile. A relationship is derived for "V" profile charges showing the extent of central segregation with furnace size.|
