In addition to iron ore fines, briquetting can also be used for bauxite, dolomite, limestone, manganese and chrome ore finessponge iron fines etc. the highpressure briquetting press lines are available from 30 tons per day to 300 tons per day. the linear pressure between the rollers is from 8,000 11,000 kgscm and the total briquetting pressure is from 150 to 500 tons. iron.
In the briquetting process, fines are usually bound using water glass with hydrated lime. there are alternatives of equivalent quality, such as sulfite lye or molasses. for the cold briquetting of sponge iron, specific pressing forces in the range of 100 to 120 kncm are required, with similar forces being applied in the hot briquetting process hbi.
Iron ore burden is such that the ascending column ofses interfaces with the maximum surface area of the iron ore the higher the content of iron ore fines in the feedstock, the lower the permeability of the burden. the iron ore feedstock pellets and lump ore is therefore screened to remove fines before being charged to the furnace.
