Self-Adjusting Skirting Reduced Belt Conveyor Maintenance


Self-Adjusting Skirting Reduced Belt Conveyor Maintenance

    USA – A innovator of modern bulk material handling technology has introduced a novel conveyor belt skirting system with a streamlined design engineered to fit virtually any conveyor with less maintenance and more efficiency. This 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. It is an adaptable solution for an entire bulk material processing system across many different industries.
      “As bulk material is processed, the belt conveyor speed, load and volume can change which can affect the integrity of the skirting seal”, said Senior Product Specialist Dave Mueller. “One skirting system across the whole line that adjusts automatically to these diverse variations dramatically cuts man hours needed to maintain it”.
      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 manual regular maintenance, fugitive material escapes from the belt, getting into bearings and other components, which can cause expensive and unnecessary production delays. The innovator 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 only 1.25 inches (33 mm) of free belt area, making it the ideal fit for conveyors with chutes close to the belt edge. The durable EDPM rubber sealing strip is 0.75 inches (19mm) wide and provides 2 inches (51mm) of wear life, at speeds up to 700 fpm (3.55mps). The sealing strip is supplied in continuous length up to 100 feet (30.48 meters) and reducing the chances of leaky joints.
      “Other skirts require manual adjustment, which means near constant monitoring,” Mueller said.  “Without monitoring — aside from the mechanical issues and product loss that accompany fugitive material — there are safety and regulatory problems that can arise, as well.  By designing a self-adjusting skirting system, customers not only save time and money on maintenance, but also mitigate the potential for injury and liability.”

Installation and Skirt Replacement

    Changing the rubber sealing strip on most standard conveyor skirting systems typically requires multiple tools, and some need two workers, depending upon the size and position of the conveyor.  These maintenance requirements could demand conveyor systems to be placed farther apart, diminishing production space.  Martin Engineering designed a simple rubber clamp assembly requiring no tools to change the sealing strip.  The low profile skirting assembly needs only six inches (1.52 mm) of clearance, allowing installation of skirts in restricted space areas.  The whole unit is compact, with the clamp assembly (wear strip and pressure plate) only 48 inches (1219 mm) in length and each clamp section having built-in plug-weld guides to simplify installation.
