Product Introduction
Polyurethane tension screens are screening media manufactured from high-strength polyurethane with a pre-tensioned structural design. It incorporates an embedded metal framework for reinforcement to absorb tension, thereby enhancing resistance to strain and load. making them widely used in vibrating screens for the classification and screening of fine-grained materials. QIUSUO's polyurethane tension screen is securely fastened to the screening machine via a tensioning device, enabling long-term stable operation under high-frequency and heavy-vibration conditions. Its exceptional wear and tear resistance significantly extend equipment service life and improve screening efficiency.

Features
● High wear-resistant polyurethane material
The material offers excellent wear resistance, corrosion resistance, and elasticity, making it suitable for high-intensity operating environments.
● High structural stability
Pre-tensioned design and edge reinforcement effectively prevent detachment and loosening during operation.
● High aperture precision and superior anti-clogging performance
It is precisely molded to ensure aperture consistency, suitable for screening wet or easily clogged materials.
● Noise reduction and vibration absorption for material protection
It exhibits excellent vibration absorption and noise reduction properties, effectively reducing material breakage during the screening process.
● Easy maintenance and rapid replacement
Polyurethane tension screens can be replaced quickly, minimizing labor requirements and downtime.
Applications
Polyurethane tension screens are extensively utilized in mineral processing, sand and aggregate production, coal washing, and related process stages. They are suitable for a wide range of operating conditions, including dry screening, wet screening, dewatering, desliming, and material washing. Owing to their stable screening performance and abrasion resistance, they are particularly well-suited for high-frequency vibrating equipment and continuous operation environments, exhibiting excellent adaptability and durability in the processing of ores, coal, and various industrial bulk materials.
