MAX-Out Wear Life

Wear Life
There are certain screening applications that require nothing less than America’s Toughest Steel! With precision plasma burnt holes, in any shape or pattern, our through-hardened MAXWEAR Steel Perforated Plate screens (also referred to as Punch Plate) are designed to handle the highest impact and abrasion materials with ease – wearing 6-10X longer than woven wire!

Did you know that a MAXWEAR Perf Plate screen can provide 6-10X longer wear life than a woven wire screen without compromising open area and that it can be installed anywhere that a woven wire screen can be installed, either flat or crowned? In fact, a correctly configured Perf Plate screen can actually increase open area over traditional woven wire!
When using woven wire, there will always be a tradeoff between wear life and open area – an increase in wire diameter will improve wear life but it will also reduce open area because the wire necessarily takes up more space. The thickness of a woven wire screen and the space between the holes will always be the same because they are both determined by the wire diameter. A MAXWEAR Perf Plate screen solves this problem because the thickness of the steel plate and the bar size are independent variables! It is possible to have closely arrayed holes in a thicker plate resulting in a longer wearing screen with more open area.
A MAXWEAR Perf Plate screen can also be repaired in the field, when necessary, further increasing the long-term wear life value of this rugged, versatile screen.
Eliminate Pegging & Blinding!
Eliminate Pegging
& Blinding!
Our state of the art, high definition plasma tables can create openings in any shape or pattern to solve just about any material challenge. Round, Hex, and Octagonal Holes virtually eliminate the pegging and blinding that the square openings in woven wire screens are so prone to. Additionally, we plasma burn each hole to be slightly conical in shape, meaning that the bottom of the hole is slightly wider than the top, further reducing the likelihood of material pegging.

Screen Configuration
Tips
Maximize wear life & screening productivity – by understanding the benefits and trade-offs of each Perforated Plate/Punch Plate screen configuration option.
Blank Outs
Strategically placed blank-out areas can offer significant wear life benefits by protecting the screen surface in high impact zones, without sacrificing thru-put.
Skid Bars
These 2” high steel bars, welded onto the screen’s surface, running directionally with material flow, can serve multiple functions. Skid bars shield the screen surface from high impact oversize material while allowing spec material to pass through – essentially screening material in two planes! Skid bars also help channel material, distributing it evenly along the screen’s surface, speeding up stratification and eliminating high wear points.
Plate
Thickness
A major benefit of the perforated plate design, is the fact that it can be configured for optimal Wear Life and Open Area! The overall thickness of a traditional wire screen is determined by the thickness of the wire itself. Thus, a thicker screen requires thicker wire, which necessarily takes up more space between each opening, reducing overall open area. A thick steel plate can be configured with closely arrayed holes for maximum Wear Life and Open Area!
*Note: A moderate trade-off between plate thickness and open area will exist in an inclined deck installation. The effective open area of each hole decreases as the deck incline increases. Horizontal decks will not see a reduction in open area as plate thickness increases.
