FAQS
The lifespan of an aggregate shaker screen varies significantly based on factors like the abrasiveness of the material being processed, the operating conditions, and the quality of the screen itself. Generally, high-quality screens constructed from durable materials like polyurethane can last between 6 to 12 months under normal operating conditions. Regular inspection and maintenance can extend this lifespan. However, in extremely abrasive environments, the lifespan may be reduced to a few months.
Selecting the appropriate mesh size is crucial for optimal separation. It depends on the size of the particles you need to separate. If you need to remove very fine particles, you’ll require a smaller mesh size. Conversely, if you’re separating larger aggregates, a larger mesh size is appropriate. It's advisable to start with a trial run using different mesh sizes to determine the best fit for your specific material characteristics. Consulting with an aggregate shaker screen specialist can also be extremely helpful.
Screen blinding occurs when fine particles become lodged in the screen openings, reducing throughput and efficiency. This is common when processing materials with a high percentage of fines. Preventing blinding involves optimizing the feed rate, using pre-screening techniques to remove excessive fines, selecting screens with anti-blinding features (like self-cleaning designs), or implementing vibration adjustments. Maintaining proper screen tension also helps.
Aggregate shaker screens are commonly made from stainless steel, polyurethane, woven wire mesh, and composite materials. Stainless steel offers good durability and corrosion resistance. Polyurethane provides excellent abrasion resistance. Woven wire mesh is cost-effective for less abrasive materials.
