A preliminary analysis of smooth roll crushers
Research is conducted on a small industrial scale smooth DRC at the Institute of Mineral Processing Machines. Results of the crushing force dynamics under extreme conditions, as well as the related product particle size distribution and the influence of the mineral structure of a variety of rocks on the nipping behavior are presented.
COKE PRODUCTION FOR BLAST FURNACE …
The coke properties can be grouped into following two groups: a) Physical properties and b) Chemical properties. a) Physical Properties: Measurement of physical properties aid in determining coke behavior both inside and outside the blast furnace (Figure 4). In terms of coke strength, the coke stability and Coke Strength After …
Influence of Selective Crushing and Particle Shape of Shaft
Both shaft and hearth coke, unblended and blended, benefitted from jaw crushing. Roll crushing produced a less favorable particle shape for packing than jaw crushing, thereby decreasing VBD. This study found that the shaft coke tested was generally more sensitive to the negative effect of smooth roll crushing than the rotary …

more "shear" like crushing action (e.g. disc mills or roll crushers). The approach used in this project to clarify the impact of laboratory crushing/shape on VBD has been to screen Run of Kiln (RoK) coke to remove the fraction tested for shape and Bulk Density (Usually, -0.6 + 0.3 mm), and then crush the sample using the chosen crusher ...
Calcined Coke Particle Size and Crushing Steps Affect Its
Data, showing how calcined coke particle size and crushing steps affect the VBD result will be presented. These data help explain why the roll crushing steps need to be controlled to improve VBD repeatability and reproducibility. In addition, data will be presented showing how the roll crusher operation and maintenance affects the VBD result.
