Jul 07, 2017 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. In case of limestone addition through sintering, these days calcined limestone (lime) is also directly being used.
