Polyurethane dewatering screen plates | Specially designed for sand washing in the mining industry: highly wear-resistant, anti-clogging dewatering screen mesh

Key Performance Data

• Exceptionally long service life: With wear resistance 8–10 times that of standard metal screen plates, the service life under normal operating conditions can reach 8,000–12,000 hours, significantly reducing the frequency of replacement.
• Efficient Dewatering and Anti-Blocking: With a slotted aperture ratio of 32%–45%, the flexible screen self-vibrates and self-cleans. The blockage rate for wet sand and coal slurry is below 5%, ensuring thorough dewatering and minimal sand loss.
• High Strength and Impact Resistance: With a Shore hardness of 90±3 and high tensile strength, it can withstand high-frequency vibration and material impact over the long term. It does not crack or deform when submerged in water.
• Noise Reduction and Vibration Damping: Noise levels are reduced by 15–20 decibels compared to steel screens, protecting the equipment’s main beams and extending the service life of the entire machine.
• Quick Installation: Compatible with both hook-and-loop and bolted mounting systems, suitable for the full range of high-frequency dewatering screens, making disassembly and assembly quick and effortless.

Applications：

Widely used in applications such as sand washing and fine sand recovery, dry tailings disposal, coal slurry dewatering, wet washing of mining aggregates, and slurry solid-liquid separation.

Production Capabilities：

Daily production capacity of 300–500 sheets. We offer customised specifications including hole diameters of 0.1–5 mm, thicknesses of 15–35 mm and lengths of 0.5–3 m. We can also produce wear-resistant, thickened, flame-retardant, anti-static and hydrolysis-resistant formulations to meet specific requirements.

Polyurethane dewatering screen plates：

(slotted type, designed for dewatering and anti-clogging)

• Yellow standard dewatering screen plates (hook-mounted / bolted)
• Red wear-resistant dewatering screen plates (designed specifically for coal washing in mines)

Installation Guidelines：

(Suitable for Dewatering Screens)

• Dewatering screens typically use slotted polyurethane screen plates, featuring a hook-and-loop quick-fit system or bolted heavy-duty fastenings.
• The screen mesh should be tensioned to the correct degree to ensure high-frequency vibration, prevent clogging of the mesh openings, and achieve thorough dewatering.
• Suitable for: fine sand recovery, dry tailings disposal, coal slurry dewatering, and slurry dewatering.
