The crushing strength index of ferro-coke can be expressed by the following formula, Equation (1): Crushing strength Index = m30 m0 × . (1) where m0 is the initial mass of the ferro-coke before crushing, and m30 is the mass of the ferro-coke whose diameter is greater than 10 mm after crushing 30 min. 2.2.3.
control the rate of coke falling onto a conveyor belt, which carries the coke to a crushing and screening system. The coke is then crushed and screened to the proper size for the blast furnace operation. The sized coke is transported to a storage area where it is kept until ready for use or shipment. 12.2.1.4 Byproduct Collection -

Simply, in this context, screening involves separating particles of an ore according to size and, often, geometry. This is the primary reason why screening is performed. The screening process typically follows after comminution processes such as primary crushing and secondary crushing. There are different types of screens available.
