The complete set of equipment that links the division of pulp into a paper web is generally referred to as a paper machine, including the main engine such as the headbox, the mesh part, the pressing part, the drying part, the calender, the paper reel and the transmission part, and auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery.
A machine that copies pulp aqueous suspension that meets papermaking requirements into paper through the processes of filter dehydration forming, mechanical extrusion dehydration and drying. The paper machine includes three main parts to complete the above process of forming, pressing and drying, and is equipped with necessary finishing, winding and transmission devices, as well as pulp supply, slurry and white water circulation, vacuum, ventilation and exhaust, paper loss treatment and lubrication, automatic control and other auxiliary systems. The specifications of the paper machine are often expressed by the width of the paper (referred to as the width), the width of the copper screen and the preferred working speed. The width of modern large paper machines can reach 3m, the working speed is more than 11m/min, the daily output of paper is hundreds of tons, and the weight of the whole machine is more than 1000,1 tons, up to more than 3 meters. In general developing countries and the production of some special paper, more used for small paper machines, its width of 200~<>m, working speed tens of meters per minute to <> meters.
