A Blaine number is the surface area-based parameter that is quantified with the use of the air permeability method. The technique is well-established in the cement industry. However, it has several widely recognized and important limitations. These include 2 types of cement of the same Blaine number exhibiting different characteristics in …

Raw material preparation includes the grinding and mixing of pellet feed materials [3]. Iron ore pellets are extensively used in downstream reduction processes, i.e., Blast Furnace, ... Blaine number of iron ore fines was measured as 2920/cm 2.g −1. It illustrates that the particle size distribution and fineness of the iron ore fines satisfy ...

Grinding Roll ("HPGR") technology is also applied in regrinding of iron ore pellet feed concentrate. relatively large number of units have been or ar e being installed in iron ore pellet feed ...

The paper analyzes tests with an iron ore concentrate sample carried out over a range of pressures, roll velocities, feed size distributions and moisture contents in a pilot-scale facility. It is observed that specific throughput drops as the operating pressure is increased, a parabolic profile appears along the rolls regarding both Blaine ...

The high-grade iron ore fines contain 64% Fe, 2.25% LOI, and Blaine number 2975 cm 2 /g, whereas iron ore slimes contain 52.45% Fe, 5.60% LOI, and Blaine number 7046 cm 2 /g. Pellets were produced without using bentonite as the binder. The pellet properties, such as drop number, green and dry compressive strength and …

During past nearly thirty years, High Pressure Grinding Rolls (HPGR) has been utilized in size reduction of iron ore concentrates prior to pelletizing processes (Campos et al., 2019). ...

Blaine number is another important aspect to influence green ball formation. Although Blaine number of ground iron ore fines is controlled during iron ore grinding in raw material preparation area. At times, it becomes difficult to maintain required Blaine number (1800-2200 cm2/gm) with change in iron ore characteristics. ...

A.P. vs. Blaine Fineness–Iron Ore /Iron Ore No.2 . In the context of Blaine fineness, Iron Ore No.2 pellets show less porosity due to the finer proportion of grains in concentrates. Blaine 1989, 2311, 2879, and 3461 cm 2 /g contain smaller grains than 44 microns in the proportion 48.2, 53.2, 65, and 78 weight %, respectively. This …

Through Design of Experiments (DOE), nine experiments over each iron ore mixture were done, varying the minimum and maximum grinding operational parameters. Independent variables (responses) were the specific surface area or Blaine index (BI) and the particle size (PS), which were measured by the automatic PS analyzer system (PSI).

Banded iron ore such as BHQ is one of the potential resources of iron having a total iron content, i.e., Fe (T) of 35–48 wt%, which is lying unutilized in most of the Indian iron ore mines.

Iron ore concentrate is used as the fresh feed of pelletising plants.
