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

The method of feeding is important. Unless the entering ore is spread evenly over the whole width of the rolls, partial wear occurs, causing the surfaces to become grooved or flanged. A heavy-duty crushing rolls incorporate a “fleeting” mechanism which causes one cylinder to move to and fro on its axis, thus reducing this type of wear
