Effect of Coal Briquette Size on Coke Quality and Coal Bulk
2019820 In tests 3 and 4, SV for powder coal and pre-briquette coal are as low as 1.51–1.52 and 1.71–1.84 respectively because blend 3 contains 40% of semi-soft coking coal. These tests are expected to reveal the effect of the briquette size on coke quality in using large amount of semi-soft coking coals. However, in cokes produced by the

The coal is transferred from the mixing bins to the coal crusher where it is pulverized to a preselected size between 0.15 and 3.2 mm (0.006 and 0.13 in.). The desired size depends on the response of the coal to coking reactions and the ultimate coke strength that is required.
