Static Control for Pneumatic Conveying Static Removal

Highly charged slitter trim materials cling to the sides of the cyclone of the trim collection system, forming a clog across the exit duct. The trim collection system must be shut down - affecting all operations producing slitter trim. The Conveyostat system controls static on trim materials prior to entering the cyclone. Once neutralized, the materials flow smoothly throughout the system, eliminating system shutdown.

Electrostatic Charging on Dry Bonding Web/Sheet Lamination

Chargemaster power supplies and charging bars work to bond the substrate and the laminating material. The materials pass between the two bars without contact and are electrostatically bonded. This ensures that materials remain aligned during the lamination process.

Static Control on Rollers

Particulate is attracted to a charged rubber roller causing impressions from the contaminant to be transferred to the paper. A Blue Bar installed facing the roller takes the charge off the roller.

Static Control on Accumulators

Static charges can build up on a web in an accumulator. When charges become too high, the web may attract to itself or other surfaces, and the accumulator may not extend to its full range.

Place R51 Static Bars, which are very high output bars, in the open areas between the folds of the web (see diagram). If the opposing sides of the web are within 2" or 3" of each other, mount the bars with the pins pointing up. This eliminates the need for two static bars within one fold. Further than 3", two bars may be required within each fold.

Static Control on an Open Web

Static charges on an open web can attract dirt, shock operators and cause product defects. A Blue Bar will neutralize the static charges, eliminating production problems. The Blue Bar neutralizes static charges on webs at speeds to 2500 fpm at 1" and can be mounted up to 6" from the web at slower speeds.
