Peripherally Drilled Rolls or Centrally Cored Rolls

Hence, water circulation passages for cooling are an essential feature of the roll design in rubber mills. These passages allow a pre-defined circulation of the cooling agent (mainly water) and ensure that the temperature can be kept within a prescribed tolerance over the entire face length of the rolls.

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

After a roll change or a mill stop rolls need some time to return to stable thermal conditions, every new bar entering the mill creates an impact, and sometimes there are really severe rolling accidents, due to faults by operators, weak rolled materials with internal defects, or because

Water, Oil, Air, or None? : Plastics Technology

Mar 26, 2012Air cooling is very gentle compared with water, as the heat capacity of air is about one quarter that of water. However, with modern air-cooling jacket designs, their efficiency approaches that of water cooling. Air cooling also eliminates the piping and valving needed for both water or oil systems and results in a more streamlined extruder design.
