Consequently, the porosity and water absorption are much lower than those of ACBFS or expanded blast furnace slag. Pellet sizes range from 13 mm (1/2 in) to 0.1 mm (No. 140 sieve size), with the bulk of the product in the minus 9.5 mm (3/8 in) to plus 1.0 mm (No. 18 sieve size) range. Pelletized blast furnace slag has a unit weight of about 840 ...
Pelletizing plants are expected to play an important role in an era when the global reserve of high grade lump ore is shrinking. The plants promote the concentrating of low grade iron ores into upgraded pellets, which will be increasingly used by blast furnaces and direct reduction furnaces in coming years. Iron ore pellets

Basic Oxygen Furnace (BOF) The basic oxygen furnace is the process in which a mixture of scrap (25 to 30 percent) and hot metal (75 to 70 percent) from the blast furnace is exposed to oxygen blown at a high velocity into the bath. Such furnaces may be top-blown, bottom- blown, or a combination of the two.
The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.

Furnace size has increased markedly, however, and one large modern furnace can supply a steelmaking plant with up to 10,000 tons of liquid iron per day. Throughout the 20th century, many new iron-making processes were proposed, but it was not until the 1950s that potential substitutes for the blast furnace emerged.
The available capacities are from 500 tons to 3,000 tons per day. A vertical roller mill combines intermediate crushing, grinding, drying, separating & conveying processes. While grinding the slag, the fineness will be as per Blaine > 4,200 cm2/gram. The initial moisture of 15% in the slag will be reduced to 0.5% in the process.
In case of failure of EOS, the situation of a (partially) closed sinter plant was tested. Purchased pellets replaced sinter, leading to a pellet and an 80% pellet/20% sinter trial. The trials were executed in the first half of 1994 at blast furnace No. 6, equipped with a PW-bell less top. Results are described.
