· Elastic deformation of the mill takes place during rolling. Mill spring can be avoided, if stiffer rolls are used which means that the roll material is having high stiffness or elastic constant. Normally elastic constant for mills may range from 1 to 4 GNm1. Roll elastic deformation can result into uneven strip thickness across.
· The grinding process by roller mills requires high grinding forces between the grinding elements. The forces have to be generated and transmitted to the .
