Screening is an important step in the secondary fiber production process.
??
After the secondary fibers pass through the coarse screen with round holes, the remainder should all pass through the fine screen to better disperse the interfering substances and contaminants such as paper blocks, cellulose, stickies, stickies, hot melts and other impurities .
??
The impurities are more concentrated after each screening, and at the same time, the loss of fibrous materials must be avoided. The quality of the final product paper or board depends on the efficiency of the screening system adopted. Each screening machine manufactured according to mechanical design standards and water conservancy standards is used as a closed device, and the best screening effect can be adjusted by the two additional main components, the screen frame and the rotor. The relationship between the working elements and operating parameters of the screen machine largely determines how much installation purpose is achieved. In this way, it is necessary to adopt the screen frame with the narrowest gap and match with the contour of the screen surface which can run smoothly. The role of the rotor is to feed the pulp and clean the screen frame. When the soft and elastoplastic interfering substances change the operation mode, it is impossible to pass or block the sieve gap.
??
Special attention should also be paid to the purifier to remove small and particularly heavy particles. The well-dispersed stickies and contaminants can only be removed with a purifier. In addition, the geometry of the purifier is mainly composed of a single piece, so it does not affect the centrifugal force and flow direction. It should also be particularly resistant to wear.
