Degradation of blast furnace coke during handling and transport can produce up to 5% of -10 mm size and so reduce the +80 mm component to less than 2-4%. In shatter tests the action is one of crushing, creating smaller pieces out of a large piece and so, in effect, increasing uniformity and strength. Different size cokes differ in strength and physico-chemical properties, and are also affected by the quenching method (wet or dry) used. The most important parameter as far as blast furnace coke is concerned, in the interests of uniform size and sustained strength, is the M10 index, showing the yield of -10 mm fines, as it is these which detract from furnace performance.
