Causes of Vibrating Screen Malfunctions in Paper Mills

In a paper mill, the Vibrating Screen is often used for coarse screening or tailings treatment. It works in a tough environment with high moisture, abrasive pulp, and continuous vibration. The problems of a Vibrating Screen do not happen alone. They follow a bad chain: screen clogging leads to less screening area, which makes the material layer too thick. This causes load imbalance and finally leads to mechanical damage. This damage shows up as abnormal vibration, broken bearings, or a broken screen plate. The most common issues are clogging and wear. Pegging happens when particles get stuck in the holes. Blinding happens when fine particles or stickies cover the screen surface. Wear is caused by sand, glass, and metal hitting the surface. A metal mesh wears out fast, and a hole lets big particles pass through, causing paper defects.

To fix these problems with your Vibrating Screen, you need smart solutions. First, change the screen material. Use a polyurethane screen plate instead of a metal mesh. It is much stronger, resists clogging better, and lasts longer. Second, add active anti-clogging devices. You can install bouncing balls or polyurethane star parts under the screen. They hit the screen bottom and knock out stuck particles. Third, keep the screen tight. A loose screen forms bags that trap material and cause local wear. You must check and tighten it often. Fourth, clean it regularly. Use brushes or high-pressure water when the machine stops. Also, make sure the spray water system works well during running to keep the holes clean. The table below shows the main problems and solutions for the Vibrating Screen:

Problem	Cause	Solution
Pegging	Particles stuck in holes	Use polyurethane screen plates
Blinding	Stickies cover the surface	Install bouncing balls or slip rings
Fast Wear	Sand and metal erosion	Use wear-resistant materials
Local Wear	Loose screen forms bags	Check and tighten the screen
Poor Screening	Spray water nozzle blocked	Keep the spray water system clean
