Iron ore pellets – IspatGuru

Dec 28, 2013 · The term iron ore pellets refers to the thermally agglomerated substance formed by heating a variable mixture of iron ore, limestone, olivine, bentonite, dolomite and miscellaneous iron bearing materials in the range of 1250 deg C to 1350 deg C. Iron ore pellets are normally produced in two types of grades namely DRI grade and BF grade.

Cold Compression Strength (CCS) Test RB 1000 - RB Automazione

According to ISO 4700, ASTM E 382 and IS 8625 Standards, RB 1000 is a fully automatic system for determination of the crushing strength of fired iron ore pellets and reduced iron ore pellets. The equipment consists of a loading unit, with an automatic handler and feeder for the samples and an electronic unit for indication, printing and statistic calculation of crushing strength test data.

Crushing Strength Testing Machine for Iron Ore Pellets ...

Crushing Strength Testing Machine for Iron Ore Pellets (AIM 675) Ref. Standard- IS04700,ASTM E 382 . Crushing Strength is the maximum compressive load at which an iron ore pellet is broken completely. Compressive load is applied on the pellet between two parallel platens at a uniform speed of 15 ± 5mm/min over the entire period.

Iron ore pelletizing systems - liming

Iron ore pelletizing systems. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel.

Use of Iron Ore Pellets in Blast Furnace Burden – IspatGuru

Jun 13, 2014 ·   Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-20 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

Standard Test Method for Determination of Crushing ...

The crushing strength aids the pellet producer in the determination of quality problems associated with the production of pellets. The crushing strength is often used by the pellet consumer as a quality indicator for performance in the blast furnace.

Iron Ore Pellet - an overview | ScienceDirect Topics

Raw material for pellets is produced by crushing and grinding low-grade iron ores—typically of the taconite class and finer than 325 mesh (0.044 mm)—and magnetically separating the iron oxide (magnetite, Fe 3 O 4) from the siliceous gangue. The fine particles are reconstituted into moist pellets about 1 cm in diameter, and then indurated by heating to temperatures approaching 1300 °C.

Iron Ore Processing for the Blast Furnace

grab the iron particles and the rest is discarded. For every ton of iron retained, two tons of waste, or tailings, are discarded. Crushing the Ore The crude taconite is delivered to large gyrator crushers, where chunks as large as five feet are reduced to six inches or less. More than 6,000 tons of taconite can be crushed in one hour.

11.23 Taconite Ore Processing

Concentration is the second step in taconite ore processing. As the iron ore minerals are liberated by the crushing steps, the iron-bearing particles must be concentrated. Because only about 33 percent of the crude taconite becomes a shippable product for iron making, a large amount of gangue is generated.
