The paper presents a mathematical model for the high consistency refining process of Fujian Qingzhou paper mill based on the specific edge load theory.

By analyzing the characteristics of high consistency beating and testing the function of paper under the different beating consistency ,it is showed that high consistency beating is advantageous to raising the strength of paper.

The paper discussed the application of medium consistency refining and the comparison of me- dium consistency refining and low consistency refining on bagasse pulp and Chinese silver grass pulp.

This paper discussed the medium consistency refining of wheat straw pulp which was used for paper towel production.

This paper studied the application of medium consistency refining in the packaging paper.

A productive experiment of medium consistency beating with noble earth alloy treated refining discs;

Application of medium consistency beating technology with ZDPM hydraulic pressure refiner in our paper mill is discussed.

The paper describes the production contrast between medium consistency beating and low consistency beating on bam-boo pulp and the results show that medium consistency beating improved the applying performance of the pulp with the physical performance improved by 23% to 63% than traditional low con-sistency beating and power consumption dropped by 32%.

Discussed internal research and production application of medium consistency refining.

This paper studied the effect of bar width of refiner plate on the refined pulp quality and energy consumption in medium consistency refining,the suitable plate bar width of the ZDPM refiner is about 5.

The paper describes about the production application of medium consistency beating in electro-photographic paper with mixed pulp of hardwood and bamboo, changes the old low consistency beating , improves the using characteristic of the poor pulp and makes some parameters of new beating technology.
