Increase Performance, Increase Productivity & Reduce Abrasive Costs
In today’s wide belt polishing plants, Menges Roller Company has found the key technical factors for contact rollers – including durometer, land-groove ratio, and rubber compound selection – are confusing for even to the most experienced plant personnel. But the Menges Engineers have over 40 years understanding these complex inputs.
We can manufacture a new contact roll for you as a complete core and cover, or we can recover your existing contact rolls. Either way, you’ll benefit from our expertise. Improper selection of contact roll specifications can cost you in production speed, abrasive costs, undesirable stock removal, and poor finishes.
Don’t just guess. Rely on Menges and get the highest-performing, longest lasting, most efficient contact roller available.
Durometer: Rollcover Hardness
Durometer is critical. The harder the compound, the higher the durometer. All compounds are available in variable durometers, so even if you know you want Nitrile, for example, you still need to decide on the durometer.
SOFT DUROMETERS – (15-50 Shore A) Used when aggressive stock removal is not of primary concern, but even processing of irregular surfaces is the goal. For fine finsihes, softer rollcovers are best.
MEDIUM DUROMETERS – (60-80 Shore A) These rollcovers achieve a median between hard and soft durometers. The roller will tend to achieve good stock removal while still conforming to work surface contours.
HARD DUROMETERS – (85-95 Shore A) Hard rollcovers are used for aggressive stock removal or when precision tolerances are critical.
Groove Angle & Direction:
For belt grinding operations, grooves should run opposed to the belt splice, which prevents the belt splice from getting stuck in the groove land.
60 DEGREE GROOVE: The maximum practical angle, it is used for heavy stock removal,where finish marks not a concern. Belt life is reduced, but cut rates are rapid.
45 DEGREE GROOVE: The most common groove angle, it gives good stock removal rates and a suitable finish.
30 DEGREE GROOVE: Used where a better finish is needed, it is less likely to generate marks and delivers reasonable stock removal rates.
PLAIN FACED (NO GROOVES): Almost exclusively for polishing & fine finishing, with minimal stock removal.
The two types of groove cuts: radius and square cut.
Square profiles are offered by most roller companies, and are sufficient for basic requirements.
But for harsh applications, Menges offers radius-cut grooves, which are stronger & have less breakage.
