Martin Engineering said its new self-adjusting skirting prevents spillage and equipment breakdown caused by fugitive material by creating a constant tight seal to the belt. The unit self-adjusts to rubber skirt wear, regardless of material volume and size diversity.
As the friction from the belt wears down the seal strip of standard skirting systems, workers have to shut down the conveyor and use tools to manually adjust it. Without this type of regular maintenance, fugitive material escapes from the belt, getting into bearings and other components, which can cause expensive and unnecessary production delays. Martin Engineering solves this problem by using a pressure arm attached to a clamp plate, which assures a constant belt seal, thus eliminating the need for manual adjustment.
The skirt requires 1.25 in. (33 mm) of free belt area, making it ideal for conveyors with chutes close to the belt edge. The durable EDPM rubber sealing strip is 0.75 in. (19 mm) wide and provides 2 in. (51 mm) of wear life, at speeds of up to 700 fpm (3.55 mps). The sealing strip is supplied in continuous lengths up to 100 ft (30.48 m), reducing the chances of leaky joints. A simple rubber clamp assembly requires no tools to change the sealing strip.
