The feed size of the material is inversely proportional to the reduction with respect to time
The mean particle size of 4mm has reduced completely in 5 hours.
The metallization =
If the time is high and the said size fraction is totally reduced, it should not be taken into consideration for calculation.
Example:
The mean particle size analysis of iron ore is as
The size ratio = 4: 12: 16
The %age ration = 0.3: 0.4: 0.3
After 3 hours the conversion will be
The percentage conversion in 5 hours for 12mm and 16m mm particles are
So, the Metallization after 5 hours on average =
After 6 hours the conversion will be
So, the Metallization after 6 hours on average =
