Hard calender: In-machine zone controllable medium and high hard calender

Performance: Our company has successfully developed a controllable medium and high hard roll calender, which is used for finishing paper before coating, improving smoothness and reducing thickness difference.

It is widely used in coated white paper and other paper types. Features: The surface hardness of the hard roller is large, and the thickness of the paper is balanced by the action of high temperature and high pressure on each area. 

The general thickness can be controlled in each zone <=0.01MM. It greatly improves the smoothness of the paper and plasticizes the surface of the paper, reducing the amount of coating.To improve tightness,smoothless and glossiness of the sheet surface. Control the thickness of the sheet. Before getting into coating improve and control the paper roughness and porosity.
