Skirting Rubber

[Trommel]

At my company we have a problem of skirting rubbers being incorrectly set on new conveyors. We usually overcome the problem by running the conveyor for a 5-10 hours and reseting the belts accordingly.

This is by no means a perfect solution , has anybody seen this problem before. Is there a test to determine how the skirting rubers should be set or is it just simply down to an experienced eye.

Trommel,

What exactly is the nature of the problem? Is the skirting rubber not clamped tight enough and so gets pushed up by the moving belt? Is it too hard? Too soft? Do you have to "reset" the skirts every 5 to 10 hours of operation, or only once after an initial run-in of 5 to 10 hours?

The CEMA Handbook and Martin Engineering's Foundation series offer advice on skirting (and skirting rubber), but I think it generally comes down to experience (as you said).

Cheers,

The problem is that the skirting rubbers are set too tight to the belt because our fitters imagine that both the skirting and the rubbers are ultimately consumable they set the skirting very tight in the hope of reducing spillage. We tried softer and a harder materials- no change. Customers complain about the state of the belts after testing.

I was hoping for a displacement/force setting such as a pulley belt. I guess the best solution is to use a measurement.

Hello Trommel.

If you want to get rid of your beltdamage by the sjirting rubbers you can mount another type of skirting.
I work at EMO in Holland, we run about 40 km conveyorbelt 1600 and 1800 mm wide and at 4.5 m/sec and had the same problem.

We now mount the Clamp Mount, skirt sealing system provided by Promati (Belgium)

look athttp:

Another provider of a system like the one I named is
Brelko Conveyor Product (South Africa)

These systems have a light contact with the conveyor, are selfadjusting until worn away and spillageproof. No more belt damage.

Good Luck

Skirting rubbers are OK for transfer, but at loading points I prefer the clip type panels that can be adjusted by the operator. You will need to see how soft/flexible you need for your location but see:-
