● Chemical pulp has the characteristics of energy saving, water saving, low consumption, high yield, less pollution and low investment.

● The two key equipments for the production of machine pulp are high-concentration disc grinding and twin-screw pulping machines.

● The biggest advantage of the twin-screw pulper is that it is energy-saving and investment-saving. It is suitable for cotton pulp production; its main disadvantage is low yield, and the quality of pulp used for medium and short fiber, especially non-wood, is not good.

●The combination of twin-screw pulping machine and high-concentration disc grinding, complementary advantages, combined with the structural characteristics of China's paper industry and the needs of national conditions, innovatively developed a new technology for the production of "double-screw pulping machine + high-concentration disc grinding" , new processes and new equipment.

● Emphasis on and breakthrough in the preparation of a variety of non-wooden machine pulp, which is the key to the development of non-wooden machine pulp. The advanced technology and equipment for the production of non-wood raw materials must rely on China's own strength to solve.
