Why does the polyurethane screen plate block the holes when used?
Under normal working conditions, the polyurethane screen plate generally does not block the holes during use. If this phenomenon occurs frequently, it means there is a problem, which mainly comes from the following aspects:
Choose screen products with unreasonable design or substandard quality. When purchasing screen products, customers should choose screen products with good qualifications, good reputation, and guaranteed quality.
After the quality problems of the polyurethane sieve plate are eliminated, the selection of the polyurethane sieve plate model becomes particularly important. The sieve holes cannot reasonably match the diameter of the screening material, which will also lead to blockage.
Materials that are too large tend to stick together during screen vibration and are difficult to separate, causing the polyurethane screen plate to become clogged. At this time, the materials need to be reprocessed to ensure that the humidity reaches the standard before they can be put into the screening equipment. The screen tension has been adjusted. If it is loose or too tight, the vibration frequency and amplitude of the screen will be insufficient, causing hole blockage. The solution is to regularly check and adjust the tension of the polyurethane screen plate to the range of technical requirements in a timely manner. Changes in the crushing shape of the material (for example, the original round particle shape changes to strip-like particles), which may prevent the material from passing through the grid smoothly. The solution is to adjust the crushing method or repair the crushing equipment to meet the requirements of the screening equipment operation. required conditions.
A brief discussion on surface cleaning and maintenance of polyurethane screen plates
In order to maintain the purity of certain materials and reduce impurities, polyurethane screen plates often use some filtering equipment, such as screen cylinders. For it, cleaning and protecting its appearance is a maintenance job. How to clean and maintain its surface?
1. Clean the appearance of the screen drum, being careful not to scratch the appearance of the screen drum. When this happens, avoid using washing liquid, steel balls and abrasives containing bleach and abrasives. Then, when the washing liquid is disconnected, use Rinse the exterior with clean water.
2. To simply remove external dust and dirt, wash with dilute detergent or warm water.
3. Bleach the screen cylinder with various acids, rinse it with water immediately, then soak it in ammonia solution or neutral carbonic acid soda solution, and clean it with mild detergent or warm water.
4. There is a trademark on the outside, which can be washed with warm water and fragile detergent. The appearance of the screen cylinder contaminated by grease, oil and lubricating oil should be cleaned with soft cloth paint first, and then cleaned with neutral detergent or ammonia solution.
When the screen drum is running, its appearance will often come into contact with materials and the external environment, so it is very important to clean and protect the appearance while avoiding scratches.
