two roll mill heat flow diagrams

Chapter 18 Feed Milling Processes

Heat imparted to the material due to the work of grinding is related to the time it is held within the chamber and the air flow characteristics Impact grinding is most efficient with dry low-fat ingredients although many other materials may be reduced in size by proper screen selection and regulated intake
