Problem

Installed on the clinker conveyor at Lehigh Cement, Martin® GravitySeal™ Self-Adjusting Skirting has improved the effectiveness of the skirtboard seal while greatly extending the life of the sealing strip.

Abrasive clinker would rapidly wear out the skirtboard sealing strips, creating a severe spillage problem at the conveyor’s loading zone. The sealing system required replacement every three weeks.

Solution

Mounted on pivoting pressure arms, Martin® GravitySeal™ Self-Adjusting Skirting floats on the belt, and automatically self-adjusts to maintain effective sealing pressure.

The Martin® GravitySeal™ Self-Adjusting Skirting automatically adjusts to keep material on the belt and prevent loading zone spillage. Martin® GravitySeal™ Self-Adjusting Skirting floats on the belt, maintaining sealing pressure without maintenance.

Supported on pressure arms between two steel plates, the rubber sealing strip rises and falls with fluctuations in belt travel to automatically maintain an effective seal. Martin® GravitySeal™ Self-Adjusting Skirting is available in lengths up to 300 feet (91.4 m) to allow installation as one continuous strip without requiring a joint along a load zone.

Results

Martin Engineering provided personalized performance by tailoring the Martin® GravitySeal™ Self-Adjusting Skirting to provide improved corrosion resistance while remaining within the customer’s budget. Installation was simple and straightforward. Installation required less time than other skirting.

Sealing performance has improved over time, as the belt-to-rubber seal has "worn in" after installation. The customer has indicated plans to standardize on Martin® GravitySeal™ Self-Adjusting Skirting on all conveyors as time and budget allow.
