Accretion or ring formation during actual manufacture of sponge iron in the temperature range of 900 0 c to 1100 0 formation is a phenomenon occurring exclusively in a rotary kiln while clusters and agglomerates are common in both rotary kiln and shaft based processes... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.

Further DetailsAccretion build up or ring formation in the kiln is normally caused by the deposition of low melting complex compounds on the refractory wall of the rotary kiln which gradually increases in thickness and takes shape of a circular ring This narrows the kiln diameter which ends up hindering material
Further DetailsAccretion formation in rotary kiln Material inside the kiln tumbles and slides and a thin layer of dust invariably forms on the surface of the refractory lining Some zones of the kiln may be specifically prone to particle accumulation and the combined effect of thermal and flow conditions results in the formation of cylindrical deposits or rings due to its rotating motion
Further DetailsJan 11 2016 · However rotary kiln performance is adversely affected by the ring formation known as accretion These accumulated sintered solid particles which gives formation of ring along the length of the kiln hinder material flow lowers the life span of kiln and productivity
Further Detailsthere is a tendency of accretion formation in the temperature range of 900 oC to 1100 oC inside the Rotary kiln refractory lining Dash et al Accretion is the catastrophic accumulation of sintered particles of solid bed which form rings at places along the length of the kilns This is a regular phenomenon in the DRI rotary kiln It narrows
Further DetailsOptimization problem discussed here for a coalbased rotary kiln to find the optimal operating conditions keeping desired targets like quality and accretion formation temperatures of kiln within
Further DetailsThe temperature profiles of the gas and charge in a coalfired rotary sponge iron kiln affect both the iron ore reduction process and accretion formation The temperature profile of charge is estimated from the eleven thermocouples TC1TC11 placed along the 80 m length of the kiln The quality prediction models are heavily dependent upon the accuracy of the measurement of TC10
Further DetailsAlthough no accretion formed in the rotary kiln the results were unsatisfactory The recoveries of nickel and iron were 526 and 376 respectively The produced ferronickel concentrate with the respective average nickel and iron grades of 26 and 256 was not a good raw material for steelmaking Table 3
