Tried and true performance and sticking with what you know works is often a hallmark of business decisions. You choose what you were taught works, and what you know works. Many aggregate plant managers and other mining operation managers know that in order to see the considerable cost or efficiency improvements, the changes they would have to make to their operations are often time-consuming and costly. However, Polydeck screen media, with its varied and customizable aperture shapes, can create significant throughput and cost improvements with very little effort required to make the change.
Historically, square apertures are the standard in screen media and what most plant managers are familiar with. You know it works, you’ve used it before, you see very little reason to change. However, we have seen operations increase their screening efficiency by as much as 10 to 20% by using varied aperture shapes in their operations. The change to Polydeck screen media is one that offers proven increased wear life, reduced costs, increased throughput and efficiency, and comes with our Wear Life and Labor Savings Guarantee. Making the change to aperture shapes better suited for the materials you are screening is a cost-effective upgrade that will significantly boost your operation’s bottom line, and the results are clear in four key areas.
1. Primary scalping and secondary screens can benefit significantly from elongated slots or VR aperture. Scalping screens are handling a considerable amount of processing work. We scalp off the top size particles for the secondary crusher and expect the bottom deck to take out the natural fines or produce base. The Polydeck team has seen scalping screens set up to make a 3/8” cut on the bottom deck, a tall order when the material gets introduced to the deck halfway down because the top deck was overloaded. This is a perfect situation to use elongated slots or VR’s to get a boost in open area and throughput capacity. The faster the top deck screens material, the more efficient the lower deck will be. The end result will be similar to getting a bigger screen due to the increased open area provided by the varied aperture shape.
