Technical design

Pulping, paper making and processing equipment adopt one-stop process design. This advanced composite design occupies small space for convenient operation and management with high level of security and atomization , and assured consistent production with steady quality.

This equipment has allocated with pulping pressure mould former, which is the most advanced mesh design. It can pulp from different tubes and fast and uniformly dehydrate into mould with extreme pressure. The produced paper is uniform and flat, good durability for lengthwise force and transverse force. Small difference between paper width has made it excellent as the fourdrinier machine. It has fitted multi-varieties and flexible quantifying scope through adjusting the pulping press. This is just coincide with the high speed of the machine and can not reject the pulp. So it has improved the production yield and increased the economic benefit.
