The paper machine production line is a large-scale continuous production line mainly composed of papermaking equipment, pulping equipment and processing equipment. The equipment has a long process flow, many systems and complex specifications and models.

The pressure screen is widely used in the papermaking industry and is one of the important equipments in the papermaking machinery​. It is a new type of recycled pulp screening equipment, a new generation of recycled pulp processing products. In order to produce better products and improve productivity, we must strictly follow the relevant operating procedures and precautions of the pressure screen. So what should be paid attention to when operating it?

Another online method is to screen the processing capacity. By reducing the thickened area at the bottom of the screen, the passing volume of the overall screen frame is increased (the heavy slag at the bottom of the screen has poor fluidity, and the area of the screen seam is seriously blocked). The side effect of this is that the processing load of the pressure screen system increases in the rear part, and it is necessary to optimize the processing capacity according to the slag-forming effect of the pressure screen two, three and the processing capacity. In order to alleviate the problem of heavy slag, many rotors are designed in a spiral or approximate spiral upward space shape, and an upward flow is formed during the rotation process of the rotor’s rotation inclination to partially offset the bottom enrichment effect.

The main function of the paper machine press section is to use mechanical extrusion to remove moisture from the paper web as much as possible, evenly and stably.

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
