Mining Polyurethane Screen Plate Material Grade |

Choosing the correct material grade is the core factor that determines the service life, wear resistance and screening stability of mining polyurethane screen plates.

Our factory adopts high-grade thermosetting polyurethane raw materials specially customized for heavy-duty mining working conditions, including 90A, 92A, 95A and 98A hardness grades, which are the most mainstream and practical material specifications for mineral screening industries. Different from ordinary civilian polyurethane materials, our mining-grade PU materials are added with anti-aging agents, anti-ultraviolet additives and wear-resistant fillers, which greatly enhance the mechanical strength and chemical stability of the screen plate. 90A grade is suitable for fine particle screening with low abrasion, 92A and 95A are universal grades for sand and gravel, coal washing and mineral separation, and 98A super-hard grade is specially developed for high-abrasion working conditions such as iron ore, basalt and granite screening.

All our polyurethane screen plates strictly comply with international industrial production standards, with excellent tear resistance, impact resistance and bending resistance, effectively avoiding screen hole deformation, screen surface breakage and material leakage during long-term high-frequency vibration operation. We fully support international standard certification systems to guarantee product quality stability 💯.

We hold complete ISO 9001 quality management system certification, ISO 14001 environmental management system certification and ISO 45001 occupational health and safety management system certification. All production links from raw material procurement, vulcanization molding, high-temperature curing to finished product inspection are implemented in accordance with standardized certification procedures, ensuring that every batch of screen plates meets global mining industry quality requirements. In terms of delivery cycle, we have standardized production lines and sufficient raw material inventory to meet different customer needs ⏱️.

The lead time for standard size polyurethane screen plates is 3-7 working days, which can quickly meet urgent replacement and routine stock-up needs of mining plants. For customized screen plates with special aperture, size, hardness and installation structure, our professional mold opening and production team can complete mass production within 10-15 working days. We will formulate exclusive production schedules according to customer order priority and project progress to ensure timely delivery without delaying the customer’s production operation. We have rich global mining project service experience and can provide authentic on-site operation reference data 📊.

We can share detailed project references and on-site service life data of polyurethane screen plates applied in coal mines, iron ore mines, gold mines, sand and gravel quarries, metallurgical mines and other scenarios. Our products have been exported to Australia, Africa, Southeast Asia, South America and other major mining areas, with stable operation effect and long service life recognized by global customers. We can provide real on-site operation videos, customer feedback reports and wear life comparison data of different material grades for your reference, helping you select the most suitable screen plate material according to your actual working conditions.

Reasonable material grade selection can effectively reduce screen plate replacement frequency, improve continuous operation efficiency of screening equipment, and reduce overall mining operation cost. Our professional technical team can provide one-on-one material selection guidance according to your screening materials, vibration frequency, processing capacity and working condition environment, to ensure the best matching between product performance and on-site needs.
