Klein PLUG FLO® Pneumatic Sand Transporter

Klein PLUG FLO® Pneumatic Sand Transporter

In 2016, Palmer purchased Klein Technology Group.

This entire line includes pneumatic conveyors, batch mixing, and cooling/classification for the foundry and rail sand industry.

Working Smarter

Conventional pneumatic conveying systems come in two broad categories: Dilute Phase and Dense Phase.

  • Dilute Phase works by vacuum or low-pressure air (up to
    20 psi) with velocities in the pipe of 4,000 feet per minute and higher.
  • Dense Phase works by medium to high-pressure air (10 to 60 psi) with velocities in the pipe of 2,800 to 5,000 feet per minute. Dense Phase systems fluidize the sand for transport and use booster (injection of additional air along the pipeline) to keep the sand in the pipeline fluidized.

However, the high velocities of the sand grains traveling in the pipeline, with either the dilute or the dense phase system, wear out pipes and bends prematurely, even when Schedule 80 pipe is used – literally sand blasting the pipe walls – causing degradation of the sand and generating excessive fines/dust. It is not uncommon to see dilute and so called dense phase fluidized systems with transport velocities approaching 3000 feet per minute and more.

The success of these systems depends entirely on keeping the material in suspension at all times by installing boosters along the line, and because of the excessive velocities required a portion of the material is always pulverized during transport.

Result:
Waste of a good product, increased fines, higher resin usage, useless downtimes and repetitive expensive repairs.

  • Klein PLUG FLO

Benefits:

Unlike conventional transporters, the KLEIN PLUG FLO® operates with:

  • No fluidization requirement eliminating product segregation
  • No boosters required, system efficiency is increased and installation costs are lower.
  • Lower transport velocities - Only 40 to 450 feet per minute transport velocity resulting in less material degradation and drastically reducing pipe wear.
  • Very low air consumption per ton.
  • Standard Schedule 40 pipe, which lowers system installation and initial startup costs.
  • Minimal maintenance due to reduced wear and moving parts
  • Standard operating sand temperature up to 120°F

The unique features of the KLEIN PLUG FLO® system make it possible to transport sand through pipelines with very little degradation. Unlike dilute and dense phase conveying systems where grain fineness reduction of 5 points and more can be experienced the KLEIN PLUG FLO® system typically stays within one half point or less. Naturally, this can mean a great deal for your operations where grain fineness must be maintained to meet quality tolerances. Lower air pressure, lack of fluidization air boosters and the KLEIN PLUG FLO® principle result in lower air consumption and therefore smaller dust collection syetem requirements at the receiver. The KLEIN PLUG FLO® system is especially suitable for granular, free flowing materials and offers lower wear and abrasion as well as minimum material separation or reaction during the transport phase.
