The quenched coke is discharged onto an inclined coke wharf to allow the excess water to drain and to cool the coke to a reasonable handling temperature. Gates along the lower edge of the wharf control the rate of coke falling onto a conveyor belt, which carries the coke to a crushing and screening system.

Gulhan Ozbayoglu, in Comprehensive Energy Systems, 2018. 184.108.40.206.2 Coal is used in iron and steel industry. Coking coal is an essential input for production of iron and steel. The largest single use of coal in the steel industry is as a fuel for the blast furnace and for the production of metallurgical coke for reduction of iron ore or for injection with the hot blast.
However, the cold crushing strength of SZ and DF were still low, which indicated the greater influence factors of cold crushing strength was the ferro-cokes porosity. The highest peak of Si in the XRD of GF revealed that the silicon powder could not react with C to generate SiC at 1100 C, so it had no bonding effect on the coal particles.
Ferro-coke, as a new burden of blast furnace (BF), can not only greatly reduce the energy consumption and CO2 emission, but also promote the resource utilization by using the low-quality iron ore and low-grade coal. However, the strength of ferro-coke decreased with the increasing amount of iron ore powder. In order to maintain the strength of ferro-coke while increasing the

Petroleum Coke Processing Technology. 1.Crushing StageBig blocks would be crushed into materials within 15mm-50mm--- the feeding size of grinders. 2.Grinding StageThe small qualified pieces would be evenly sent, by conveyor and feeder, into the grinding cavity where the materials would be ground into powder.
Ferro-coke, as a new burden of blast furnace (BF), can not only greatly reduce the energy consumption and CO 2 emission, but also promote the resource utilization by using the low-quality iron ore and low-grade coal. However, the strength of
Shortly thereafter, a coke crusher was erected near the lower end of the western row of ovens. The addition of the crushing facility produced a higher price on the market. ... The system of production at Lucerne utilized the latest technology. The line of ovens was double, and the charging larries, designed by RP engineers, were reversible ...
The ram guides the coke into a railroad car that is called the quench car. This quench car transports the coke to the nearby quench tower, where the coke is showered with water to prevent the coke from igniting as it is exposed to open air. The quenched coke is then transported to a crushing and screening system. This system processes the ...
Jun 01, 2014 The quenched coke is taken by conveyor to a crushing and screening plant also called coke crushing and sorting plant. Here the coke is crushed and screened to the required size fractions. During crushing and screening, coke is sorted in three size fractions. These are coke breeze (size 10 mm), nut coke (size 10 mm to 25 mm) and blast ...
