Throughout the modern new high-speed headbox paper machine, it basically has the following main features:(1) Adopt high-efficiency hydraulic slurry rectifying components. Through the design of different structures and sizes of the hydraulic slurry rectifying elements

The earliest used headbox paper machine​ was an open headbox with a pulping gate, which was produced in 1804 before the Fourdrinier brothers invented the Fourdrinier paper machine.

The waste paper pulping process of pulp equipment: waste paper pulping products are divided into virgin pulp and bleached pulp. The pulping process in the production of primary color pulp is mainly the decomposition, purification and deheating of waste paper.

Pulp equipment​ is the equipment used in the process of separating plant raw materials into fibers. Pulping methods can be divided into chemical method, mechanical method and chemical mechanical method.

Paper machine production line has matching Pulp equipment. Pulp equipment plays an important role in the production line of papermaking equipment. Its main purpose is to crush waste paper raw materials and make pulp. The efficiency and quality of the beating equipment is directly related to whether the raw material pulp is qualified.

Pressure screen is a common equipment used in paper mills to purify and screen pulp. The slurry brought in the pulping workshop of papermaking equipment may contain impurities such as fiber bundles, sand particles, and metal shavings
