Gypsum, a soft mineral used in fertilizer, drywall, plaster, and blackboard or sidewalk chalk, causes a mess in the facilities that process it.A drywall facility had a problem with gypsum leakage from a screw conveyor. An air seal eliminated the leakage completely. Air seals use engineered clearances and directional flow paths to create uniform pressure and velocity profiles, generating a pneumatic seal. To accommodate the inherent misalignment that may be present in many applications, a floating throttle inside the seal handles ±0.125 inch of parallel movement.
