Guoguang Group has successfully developed crown controllable roll hard calender which is used for paper sheet finishing prior to coating. Using this paper processing machine can improve paper smoothness and reduce thickness difference.

Features
With high surface hardness, the hard roller acts on the paper through high temperature and pressure, thereby uniformizing the thickness of the paper. Generally, the thickness can be controlled below 0.01mm per nip. After processed by this hard calendering machine, the paper sheet has its smoothness improved greatly and the coating weight is reduced as well.
