Effects Of Coal Inertinite Size On Coke Strength

Components, Coal B was crushed and sieved into the fol-lowing size groups 0.1 to 0.3, 0.3 to 0.6, 0.6 to 1.2, 2.0 to 4.0, 5.0 to 7.0 and 10 to 15mm. Here, in order to homoge-nize the maceral components of the different size groups, Coal B was crushed lightly in a mortar in a manner to mini-mize the generation of fine coal.
