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.

Return fines of sinter and iron ore fines containing titanium are usually utilized with the sintering process.bb avoids heating up, softening, and melting the fine particles, which can saveot of fossil energy and manpower. size ranges of samplesndre 0.55 mm and less than 0.5 mm, respectively.

Sponge iron filter material in industry throughponge iron production equipment is widely applied iron phosphorus reduction method, method of reduction of iron ore concentrate, etc., the rolling iron phosphorus or ore concentrate after reduced iron press down into pieces, into the roasting tube into the kiln roasting, produce the high.

Sponge iron from lump ore, pellet and ore fines differences betweenot briquetting and cold briquetting the hot briquetting process.ypical hot briqutting process is only feeding the hot raw material to the hot briquette press then the briquette will be made.

Systems, oxide fines, hbi fines and dri slurry by briquetting with an inorganic binder system. the cold briquetting process itself is similar to the process shown in figure 2. the produced briquettes are directly fed into the direct reduction plant e.g. midrex and may replace ferrous materials like iron ore or pellets in the reduction shaft.

The agglomeration process in which lumps are made by compacting the iron bearing fines and dust with addition of binder and also deairing these mixtures inside the vacuum chamber of the briquetting machine. so, briquetting process is developed to meet these demands. this process aims at recycle and reuse of the low grade iron ore and plant fines.

The aim of this study was to investigate the properties of an organic binder used in coldbonded briquettes cbbs prepared from two different iron bearing materials. the applied binder isype of starch as indicated by chemical analysis, iodinestarch staining and fourier transform infrared analyses. thermogravimetric differential scanning calorimetry showed that the binder.

The iron ore used to produce hbi has the largest impact, but other factors such as the process technology also can influence its chemistry. this section presents the iso standards and internationally recognized testing procedures that, when properly applied, define the chemical composition of hbi asanufactured product.

The methodology envisages cold briquetting of iron ore fines and reductant coal along with limestonedolomite flux as compared to traditional high temperature agglomeration method. this amounts to lesser investment, easy operation and low input material handling cost and more environmental friendly.

The necessity of cold briquetting and its technological process the necessity of cold briquetting. with the development of global industry, there are fewer and fewer high grade ore in the world. asrocessing method of mineral powder, the processing of mineral powder used in the metallurgical industry generally uses sintering or briquetting.
