Pulp equipment (or refining equipment) is to make the fibrous raw materials to be processed displace the primary and secondary walls of the fibers that are moving relative to each other, and then rupture, and then the fibers absorb water and swell and are cut, and finally fine fibers Change
The main development direction of modern pulp equipment is continuity, large-scale, high concentration, multi-function, high efficiency and centralized automatic control.1. The pulp equipment is developing in the direction of medium and high concentration.
Invention and development of the paper machine. After the invention of papermaking, in the long history, after thousands of years, it has spread from China to West Asia, Europe, America, and all over the world. It was not until more than 1,600 years after the invention of papermaking that the first paper machine appeared in the world

According to the structural principle of pulp equipment, the main classifications are as follows:1. According to whether pulp equipment is continuous or not(1) Interval beater, such as Dutch beater, Volt beater.(2) Continuous beating machines, such as: column-back refiner, cone refiner, and disc refiner.
First, the slurry tankThe pulp tank of a paper machine pulp beater generally adopts a reinforced concrete structure. Simple grout tanks can also be constructed with bricks and cement. In order to make the pulp circulate well in the tank, reduce the friction of the pulp, and keep the pulp clean
