How High open areas PU Screens Overcome Production Bottlenecks in Actual Mining Operations

Most mining operations face not processing difficulties, but screening difficulties. When high-open areas polyurethane screens are too small or poorly designed, material accumulates, causing the vibrating screen to clog. The problem isn't actually with the screening machine, but with the screen itself.

How to solve this problem? Start with the screen size

High  open areas  PU Screens typically have an opening ratio between 40% and 65%, with some high-end screens exceeding 70%. In comparison, traditional steel screens have an opening ratio of approximately 30% to 35%. A higher opening ratio means faster material throughput, a thinner screen bed, and the screen can truly function effectively. Screen aperture sizes range from 6 mm to 100 mm, while panel thickness is determined by the feed rate, ranging from 12 mm to 50 mm. Hardness is typically between Shore A 70 and Shore A 95, which is ideal for most ore and coal applications. These panels can handle abrasive materials and have a lower incidence of clogging or blind holes.

Key Advantages of High- open areas Polyurethane Screens

First, compared to ordinary screens, they operate with lower noise, significantly improving the working environment for workers. High-open areas screens also exhibit more stable vibration, greatly increasing work efficiency. Furthermore, because polyurethane absorbs impact rather than transmitting it, high-open areaspolyurethane screens have a longer lifespan, typically three to four times that of steel screens.

If you are experiencing a production bottleneck and no other issues exist, the screen is likely the culprit. Switching to large-aperture polyurethane screens is not just an upgrade; it's a direct way to increase output without adding new equipment.
