mixing bins where the various types of coal are stored. 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.
