Chapter 18 Feed Milling Processes

These are smooth or corrugated rolls rotating at the same speed set at a pre-determined distance apart with material passing between the two A tearing action may be added by operating the rolls at different speeds and by corrugations which are different for each roll i e the top roll may have off-radial spiral corrugations and the bottom roll lateral corrugations This last type called a
