COKE CRUSHING CHARACTERISTICS

coke from the crushing tests are plotted against tumbler stability in figure 2. Even though sizing results are scattered, very definite trends are shown for both screen- ings and the plus 1/2-inch sizes. Although it is hard to assign values to the amount of dust produced when crushing small samples of coke, visual observations were made.

How a Coke Plant Works - GASP

Oct 04, 2018  How a Coke Plant Works. Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.

However, the role of the coke as a permeable medium is crucial in economic blast furnace operation. The degradation of the coke varies with the position in the blast furnace but in all cases involves the combination of reaction with CO 2 , H 2 0 or 0 2 and the abrasion of coke lumps against each other and other components of the burden.
