A METHOD OF AGGLOMERATION OF FERROALLY FINES SUCH AS FERROMANGANES, FERROCHROME AND FERROSILICON FINES

摘要

This invention relates to a method of agglomeration of ferroalloy fines such as ferromanganese, ferrochrome and ferrosilicon fines comprising the steps of crushing ferroalloy fines below 10mm size obtained from ferroalloy casting floor and obtaining 0-3mma size fraction on sieving; mixing the resulted fines with a phenol formaldehyde resin binder in a vessel; compacting the mixed fines in a compressive machine upto 5 ton load capacity in batches on conveying the mix in the compressive machine to obtain agglomerates of ferroalloys; curing the agglomerates on heating in a furnace in the range of 150-200°C for an hour and furnace cooled for another one hour; followed by characterize testing of the cured agglomerates for their tensile strength, tumbler index bulk density, compressive strength and abrasion index.
