Relationship of particle size, reaction and sticking behavior
1 天前 The relationship of particle size, reaction and sticking behavior of iron ore fines toward efficient fluidized bed hydrogen reduction were systematically investigated at 600-800 o C in a laboratory fluidized bed. First, the reduction kinetics were studied, and the results showed that hydrogen reduction of granulated iron ore was controlled by reduction reaction, and the

Effects of Particle Size of Coke on Iron Ore Sintering Process
2019-2-13 Coke breeze is the main heat source in sintering process. Its combustion yields enough amounts of heat which melts the sinter mix. One of the factors that significantly affect the course of coke breeze combustion is its grain size [1,2,3].It is known that fine-grained coke reduces permeability of the sinter mix and the use of coke breeze with particle size below 1

2012-8-16 iron ore. Fig. 3.3 : Effect of size of ore on degree of reduction. Iron ore and agglomerates as charge material should be resistant to abrasion. If they break into finer fractions due to impact, abrasion, compression and volume change within the furnace, the smaller particles result in choking of voids thereby affecting reduction and productivity.

Investigation on the particle size and shape of iron ore
Particle size and shape are important parameters that can significantly affect mineral processing plants and pelletizing plant performances (Brozek and Surowiak, 2007). For example, using finer particles (with a certain size) in magnetic separation could improve the iron grade. The shape of crushed ore affects the product particle size in a
