Polydeck Screen Media

Howe Systems and Polydeck Screen Corporation have partnered together in the mining industry for 25 years. Polydeck’s expertise combined with Howe System’s commitment to service provides the following improvements to screen media: (1) extending panel life, (2) improving gradation, (3) solving feed drop issues and (4) maximizing throughput.

The video below represents two screens running simultaneously side-by-side for a customer with multiple double deck tertiary screens cutting at 13mm.  The video on the left shows a competitor’s media.  We were asked to perform a test on one complete screen (shown on the right) to improve the life and throughput without changing the aperture size.  As you can see in slow motion, the Polydeck media had very minimal fines discharging off the bottom deck while the competitors show fines being recirculated back to the cone crusher, increasing the recirculating load.  Not only was the life of the media improved, but the throughput increased due to the reduced recirculating load.
