What is the second step in making coke?

Explanation:
Crushing coal into the right, smaller size is the essential preparation step before the coke ovens. Breaking the coal down increases the surface area and allows heat to transfer more evenly during carbonization. When the coal is already properly sized, volatile components can escape more uniformly and the resulting coke forms with consistent structure and quality. This sizing happens before the coal is charged into the oven and heated to drive off moisture and volatile materials. Washing and sieving are cleaning steps that may occur earlier, and the actual charging and long heating happen after the coal has been sized.
