摘要：

In coal-based DRI process, accretion formation inside the rotary kiln is a genuine complex problem. Accretion formation in a rotary kiln of 100 tpd DRI plant has been investigated. The nature of accretion formation with respect to the charge burden and operational parameter have been discussed. High ash content in the coal and excess use of dolomite lead to accretion formation. Two different types of accretion are revealed; the major one is due to agglomeration of DRI by-products while another one is sintered product of DRI.
