Diagram of Coke Production The coke production process takes place in coke chambers. First, selected types of quality coking coals are mixed in a certain ratio in the coal charge, which is subsequently ground and then transported to coal towers. Charge from coal towers is taken by the stamping machine, where it is tamped into large coal prisms.
