In industrial operations including mining, aggregate processing and coal preparation, screening precision and equipment durability directly determine product quality and operational profitability. Traditional metal screens often suffer from frequent clogging, low grading accuracy and short service life when handling abrasive or sticky materials, leading to 30%+ production downtime and rising replacement costs. Polyurethane Screen Mesh, featuring a special flexible pore structure, high wear resistance and hydrophobic surface, solves these pain points efficiently, delivering 25% higher screening precision and 3-5 times longer service life than traditional steel screens. This article elaborates on its working logic, applicable scenarios, practical cases and economic benefits, offering professional guidance for equipment selection.
