Our polyurethane fine screens are widely used in industries such as mining, chemical, metallurgy, and construction. They can be used in conjunction with various electromagnetic vibrating high-frequency screens, composite vibrating high-frequency screens, and stacked high-frequency screens, making them particularly suitable for the precise screening of fine-grained materials. QIUSUO uses high-quality polyurethane materials combined with high-precision mesh design, making PU fine screens not only have excellent screening accuracy but also a longer service life, and effectively reducing maintenance costs and equipment downtime in production.
