Attrition characteristics of iron ore by an air jet in gas-solid fluidized beds

The effects of superficial gas velocity (Ug=1.25–3.00m/s) and distributor hole size (8.0–12.4mm) on the attrition rate of iron ore in a gas-solid fluidized bed with 0.076m ID×3.7m height with or without solid circulation have been determined. The particle density and the Sauter mean diameter of fres...
