A simple mill with only single upper and a lower rolls is often used for soft materials or hot rolling of harder materials where the material is quite plastic. The forces on the rolls can be huge and they deflect so it's common to profile them so they deflect to a shape that achieves the desired dimensions of the rolled section.
รายละเอียดเพิ่มเติมRoller mills use the process of stress (which is applied by the rotating wheels) and attrition in milling of solids in suspensions, pastes or ointments, and some solid materials. The rollers rotate at different speeds and the material is sheared as it passes through the gap. To obtain the desired particles size, the following should be controlled;
