Polyurethane Fine Screen Panel is specificialed for Derrick Stack Sizer

Polyurethane high-frequency fine screens have emerged as a transformative solution in coal washing plants, revolutionizing the efficiency of coal processing and purification. These screens, characterized by their ultra-fine apertures (typically ranging from 0.045mm to 8.0mm ) and high-frequency vibration capabilities, excel at precisely separating fine coal particles from impurities like silt, clay, and rock dust—tasks that traditional metal or woven screens often struggle with due to clogging or imprecise grading.

Crafted from durable polyurethane, these screens offer exceptional wear resistance, even when exposed to the abrasive nature of coal and the harsh, wet conditions of washing processes. Their inherent elasticity helps minimize blockages: the high-frequency vibrations, combined with the material’s slight flexing, dislodge trapped particles, ensuring consistent throughput and reducing downtime for manual cleaning. This anti-clogging performance is particularly critical in coal washing, where moisture and fine particulates frequently cause conventional screens to lose efficiency.

Beyond durability, polyurethane high-frequency fine screens enhance coal recovery rates by capturing more fine clean coal that might otherwise be lost. They also contribute to cost savings: their longer lifespan (often 4–10 times that of metal screens) reduces replacement frequency, while lower maintenance needs and energy-efficient operation align with modern plants’ goals of cutting operational expenses.
