Samscreen Has the Perforated Plate You Need

Perforated plate, or punch plate, screening surfaces have been around for a long time, which attests to their usefulness as a screening media. There is a common misconception that has been around nearly as long and that is that punch plate is only useful if you need extra wear life from your wire cloth. While it is very true that perforated plate offers extended wear life, it’s not the complete story.

Samscreen’s Maxwear™ plate will outlast wire cloth 4-6 times in purely sliding abrasion applications and many times more in high impact applications, but the beauty of plate is not only in its wear life. Perforated plate or punch plate provides the opportunity to offer the producer an engineered solution to their screening needs. When you are dressing your deck why not take advantage of all the benefits that plate conveys?

Since perforated plate or punch plates starts as a piece of steel as against a woven wire cloth, there are many options available. The first most notable one is the variety of openings available; square and slotted are available as well as round, hexagonal, octagonal, diamond, “Z” shaped, oval and square and slots with rounded corners.  The availability of this variety allows the producer to choose the best shape for the aggregate or ore or material they are processing, because one size doesn’t fit all!

Another great feature of perforated plate or punch plate is the ability to blank out areas and insert half holes.  When using wire cloth, best practice dictates that you replace the bucket up rubber when you replace the screens; otherwise you are in danger of wearing out your screen frame and causing premature wear of the wire.  No rock is screened over the bucket bar but plenty of rocks or debris catches in this area and don’t pass through, which causes exaggerated wear to the screen frame and the screen media.

With punch plate, Samscreen’s engineers will engineer the plate to have blank outs over these bars, protecting the screen frame, the bucker up rubber and the screen surface itself.  In addition, in high impact zones, blank outs can be used to absorb the materials coming on the decks and spread it out over the entire screening surface.
