The study of commercial limestone in the Lime-Soda Sinter process has shown that high alumina recoveries are possible using high grade limestones. High recovery sinter compositions using limestone appear to be in the same region as those performed with calcium carbonate reagent, and thus the results demonstrate that high grade limestone can be used as a substitute. Magnesium oxide is a

Addition of limestone through sinter is more preferred route since CO2 of limestone is driven out during the sintering process. In case of sintering, limestone is crushed to -3 mm (in the range of 85 % to 90 %) in hammer crushers before mixing it in the sinter mix. In case of direct feed to blast furnace, limestone lumps of 10 mm to 40 mm size are used.

Sinter productivity increased with increasing limestone mean particle size due to improved sinter bed permeability. Sinter with limestone mean particle size of 1.25 to 1.52 mm yielded better sinter strength and lower RDI compared to sinter with smaller or larger limestone mean particle size.

Sinter production uses a combination of limestone iron ore coke and heat to prepare the iron ore for steel manufacturing. This application is typical of many in the ore processing industry and is very similar to steel making and coal power plants. These applications present a combination of challenges to silo level measurement.

The production of high-quality sinter is crucial for assuring consistent, stable furnace productivity with a low consumption of reductants. Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption.
