Dec 01, 2020 For both the crushing strength and Youngs modulus of iron ore granules, their desired value should be the higher-the-better type. The S/N ratio is calculated as (4) S N 10 log ( 1 m i 1 m 1 Y i 2 ) , where m is the total number of tests and Y i is the experimental results of the i th test. Crushing. As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into various fractions by passing it over sieves through which undersized
