The Gericke Pulse-Line PTA PL dense phase pneumatic conveying system automatically forms dry, bulk materials into separate, pulsed slugs for highly gentle transfer at low gas velocities then injects additional air or nitrogen at key points along the conveying pipeline. Integrating these self-regulating activator groups, the Pulse-Line PTA PL reliably conveys pressure-sensitive granulates, sprayed granules, plastic pellets, non-compressible powders and other fragile materials up to 1,500 feet in mass flow while maintaining the proper length of the pulsed slugs and safeguarding the particle size and shape.
