Coke breeze is need to be crushed (normally in four roll crusher) to obtain the correct particle size (0.25 mm to minus 3 mm) for enhancing sinter productivity and reducibility. Less than 0.25 mm coke size has a negative effect on the productivity, while size fractions of – 3.15 mm to + 1.00 mm shows better yields.

For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.
