Skirt Board Sealing System

August 25, 2009

An improved version of the Apron Seal skirt board sealing system provides two wear surfaces on a single elastomer sealing strip installed along the bottom of the skirt board in a belt conveyor loading zone. When bottom side of the strip against the belt is worn, the sealing strip is inverted, providing a second service life. The system is installed on the sides of belt conveyor loading zones to contain material, eliminate spillage, and reduce cleanup expenses. It incorporates a primary seal clamped to the steel skirt board to keep lumps on the belt and a secondary or ìoutriggerî strip to capture any fines or dust that passes beneath the primary seal. The secondary seal lies gently on the belt and self-adjusts to maintain consistent strip-to-belt pressure despite high-speed material movement and fluctuations in the beltís line of travel. It is available in lengths up to 300 ft.
