osti.gov journal article: use of selective crushing technology in preparing a coal charge for coking title: use of selective crushing technology in preparing a coal charge for coking full record.liberation characteristics of indian coking coal through,coking coal is one of the important raw material for iron and steel industry. the study on available indigenous coal has reduced the dependency on imported coal for these industries. coal may be crushed to optimum top sizes as required by the industry. the top size of coal.liberation properties of middling coking coal under shear,the relationship between shear force and selective liberation of middling coking coal was investigated by crushing the coal at different shear angles (15°, 30°, 45°, 60°, and 75°). subsequent analysis of the middling coking coal revealed that as the ash content of coal increased, the shear strength and cohesion increased, while the internal friction angle gradually decreased.
at the startup of furnace 6, besides optimising its composition; it was decided to restore selective crushing of the coal batch using pneumatic and mechanical separation in the third unit of the coal preparation shop. additional increase in the mechanical strength of coke by 1.5-2.0% was predicted with a 0.5-1.0% decrease in wear..v116n2a12 effect of crushing on near-gravity material,fractions of an indian non-coking coal by s. mohanta*, b. sahoo*, i.d. behera*, and s. pradhan* +1#,0, run-of-mine coal contains particles of different sizes with different specific gravities, and when this coal is crushed, the amount of material present in a particular density class.a survey of the coking properties of illinois coals,coals from 21 mines, representing 7 seams and 15 counties, were sampled for these tests. in choosing these coals, all of the major coal mining areas in the state, as well as all of the commercially mined seams, were included. in ad- dition, one seam not mined commercially, but showing promise as a coking coal, was included.
it was confirmed in a long-term commercial scale experiment that fine crushing of high coking pressure coal decreases coking pressure and decreases maximum power current of coke pushing. a selective fine crushing of high coking pressure coal is a promising way to reduce coking pressure and to prolong coke oven life. full text pdf [1258k].coking pressure control by selective crushing of high,against this backdrop, we investigated the selective fine crushing of high coking pressure coal as a way to reduce coking pressure. it was shown on a laboratory scale that the fine crushing of high coking pressure coal increases the permeability of the plastic coal layer, which decreases coking pressure (internal gas pressure).
