The constant K 2 is also dependent on ore type and ranged from 1.4 to 1.5. A regression of Magdalinovic's data including the feed 80% passing size gives an average value of 1.485 for K 2.If we extend this relationship to any sample of screened material then this gives an approximate estimate of the 80% passing size as 67.3% of the top size.
