Before starting the machine, use hand rotation to check whether the moving parts are jammed or not, and whether the connections are tight, and then they can be idle. When operating, pay attention to whether the equipment has other abnormal phenomena.

The paper machine production line is composed of many ancillary equipment, and there are many ancillary equipment in it. Among them, the pulping equipment is one of the important supporting equipment, and it occupies an important place in the paper machine production line.

After mechanical pulp is pulverized into pulp, it generally contains incompletely dissociated fiber bundles, a small amount of wood chips, sand and dust and other impurities. Pulp equipment generally needs to be filtered, sedimented and filtered by hydrocyclones.
