bed in such a way that a zone of incipient or partial fusion passes through the bed in order to agglomerate (sinter) the fines in the bed to a porous lumpy material suitable for feed to a blast furnace. A vertical section of the sinter bed is shown schematically in Fig. 11.2.. The sintering process consists of the following five different zones :
Apr 10, 2014· Successful blending occurs with respect to non-additive properties (likes combustion reactivity of coal, ash characteristics, grindability index, and swelling characteristics) of two coals. Coal industries are using different type of blending methods such as blending in bed, blending by silo, blending by ground hopper and blending on moving belt.
Therefore, the densification process during iron ore sintering involves the creation of capillary pressure, which forces the sinter melt to spread into the pores within the packed granule bed. Therefore, granulation affects not only the airflow and efficiency of the sintering process but also the densification process in the granule bed during ...
The Ore Bedding and Blending Plant (OBBP) of Rourkela Steel Plant (RSP) has created a record in single day wagon unloading clicking 448 wagons, 13 more than its previous mark. The record was achieved on January 22 breaking its previous feat which was created on November 27, 2013, RSP sources said today.
Jul 18, 2013· The bedding and blending process of iron ores has been investigated by means of laboratory trials, industrial sampling and a mathematical model. It has been revealed in the present work that an increase in the total number of ore ingredients participating in the proportioning procedure would greatly improve the quality of the base mix.

Other articles where Blended bedding is discussed: sedimentary rock: Types: …commonly, however, the layers are blended. This variety of bedding results from a check in the velocity of the transporting agent, and thus coarse-textured sediment (gravel, for example) is deposited first, followed upward by pebbles, granules, sand, silt, and clay. It is commonly associated with submarine density ...
Successful validation of a process can result in a reduction of sampling and testing procedures and hence fewer product rejections and the need for retesting. The lower rejection rate leads to cost-saving benefits.For compliance to current good manufacturing practices, validation is essential. 3.How important is validation of dry mixing in the ...

At one pit location, the ore may be soft and easy to grind, at another hard and very difficult to grind and at a third the ore may be an intermediate type. In order to provide consistent ore grindability and hence maximize output, it would be desirable to blend these types of ore into one uniform mixture for feeding to the mill lines.
