Abstract. Experience indicates that sulfur elimination in updraft lead sintering is about 85% complete. Physical chemistry of the Pb-S-O system suggests that poor elimination may be due to sulfate formation at temperatures below about 900/dgC.
Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (limestone) fines. In addition to base mix, coke fines, flux fines, sinter fines, iron dust (collected from plant de-dusting system & ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often called mixing and nodulizing drum.

The lead-zinc sintering process Different kinds of lead-zinc ores are first blended and dried to become mixing dry concentrate. Then the mixing concentrate and returning powder are blended and granulated. The mixture is oxidized and desulfurated in updraft sintering machine to produce agglomerates and SO2 is sent to prepare sulfuric acid.
Apr 02, 2011 Continuous updraft sintering allows production on one machine of a high-quality, semireduced sinter. This method uses a thin 25–35 mm layer for downdraft ignition by gas or oil burners, before the main bed (250–430 mm) is laid. The flame front then moves upwards through the bed, as combustion air is blown from windboxes below the grate.

This sintering cogeneration technology facilitates the implementation of energy conservation and cost reduction in this field. In the sintering process, we mainly need to recovery the waste heat from the tail gas exhausted by the sintering machine and the waste gas
Updraft sintering of lead concentrates was introduced at Port Pirie in 1955 and since that time a considerable amount of investigational work has been carried out in the laboratory and on the plant with the objective of improving both the understanding of the process and its practical application. From this work it is now possible...

Nov 23, 2017 What does SINTER PLANT mean? SINTER PLANT meaning & explanation About 70% of the world's primary lead production is still produced using the sinter plant–blast furnace combination, and this
The Outotec traveling grate sintering process begins with the preparation of a raw mix of iron ores, fluxes, in-plant dust and spillage fines, solid fuel, and return fines. Water is added to the raw mix to obtain optimum permeability for lower electricity consumption, maintained by conveying the raw mix carefully onto the sinter machine.
