Size segregation in filling and emptying of a Paul-Wurth bin

In-bin segregation and the discharge segregation of a 17:1 scale model of the Paul-Wurth bin at the Port Kembla No.5 Blast Furnace was investigated. In-bin segregation was studied using two different materials (ore and coke), and two different sampling procedures, namely in-bin sampling method and freezing technigue. Comparison of these methods show that in-bin sampling could be used instead of freezing technigue for practical purposes.
