    Roll mills are also used for warming up materials for calendering or extrusion. In such cases the warm material is cut into strips that are fed into the calender or extruder often continuously. Another application of roll mills is to cool materials discharged from an internal batch mixer in a form of large lumps (see Section 4.2.3.1.2). The resulting blanket is then transported in the form of strips to the calender or extruder or removed from the rolls
