A paper machine is a necessary papermaking machine for every paper mill. The emergence of this machine has replaced the traditional manual papermaking, which not only improves the quality of paper but also improves the production efficiency. For special understanding, let the editor of China Paper I
Whether the steam supply system of the dryer section is reasonable or not has a great influence on the paper quality, steam consumption and operation management of the dryer section.This part is mainly designed according to the following principles:1) It can ensure that the temperature of each part
The main body of the paper machine and its auxiliary and auxiliary systems have different forms and specifications. In engineering design, the forms and specifications of various parts are determined based on the types of pulp used in papermaking, paper types, and output requirements.
The vacuum roll on the paper machine is mainly dehydrated by vacuum suction. Its advantages are convenient operation, high dehydration rate, less wear of the net, and convenient paper threading. The use of vacuum rolls in the paper machine can increase the dryness of the wet paper to more than 20%
The instability of the slurry concentration will inevitably affect the fluctuation of the paper weight of the paper machine. In severe cases, it will cause the paper machine to break and fail to make normal papermaking.
After the paper sheet from the drying section is calendered by the calender, the smoothness, gloss and tightness of the paper sheet can be improved, the thickness of the whole paper sheet can be consistent, and the air permeability can be reduced; Rolling into a paper roll completes the main process of papermaking. In order to meet different needs in the future, there are also calenders, rewinders, paper cutters, etc. after the paper roll in the papermaking equipment workshop.
