Mining Application Case Studies

Region: Mexico
Material: Gold Ore
Issue: Limited screen size restricted production capacity, which was magnified by use of a competitor's low open area screen panels. High circulating loads of already crushed finished product produced high wear and power draw on the crushers.
Solution: Analysis revealed that higher open area Maxi screen panels would increase production capacity and reduce power demands on the crushers.
Result: Plant capacity was increased by 30% with no additional space or screen deck modification required.

Region: South Dakota
Material: Gold
Issue: Severe blinding on the bottom decks of the customer's 7' by 16' screening operation has drastically reduced crushing and screening efficiency. Competitor's 1' by 2' synthetic screen media solution has 22% open area.
Solution: Polydeck suggested running a side-by-side comparison with the existing set-up. Polydeck provided 1' by 2' Flexi rubber VR screen panels with 39% open area to run on 2 decks in identical operating conditions against the competitor's screen media on 2 other decks.
Result: Belt samples revealed the Polydeck solution ran 796 tph with no blinding while the competitor's ran 624 tph; increased efficiency reduced load on crusher liner life which was estimated to save over $8,500 per year per crusher. Overall circuit capacity was judged to be greatly increased using Polydeck screen media solution.
