System to the Refining and Approach of Papermaking Workshop

Design of 400t Fine Paper per Day

ABSTRACT

It mainly about the Refining and Approach system of papermaking workshop

section ,which produces 400 tons of fine paper everyday.

The characteristic and design principle of approach system for fine

paper production were briefly introduced.

This design take commodity softwood pulp and hardwood pulp as the main

raw materials, after repulping, beating, matching into a pulp pool, the pulp then in sequence to a high voltage box, strong pulp pumps, purification system, screening system, flow slurry box, forming eventually transported into squeeze system . Based on the above mentioned each part ,the design to complete fine paper to \\high\quality property requirements on the reasonable and economic design .Improving the fine paper practicality.

KEYWORDS : fine paper, approach system, high purity, high whiteness, high strength ,high evenness
