Rotating Vane Wheel, Rotating Throat, Rotating Air Port

We have combined all of our years of experience and the mill operating data from hundreds of plants to optimize our Patented Rotating Vane Wheel, Rotating  Throat  and  Rotating  Air Portdesigns.  Our improved multi-vane design allows for reduced air velocity through the throat without increasing unwanted coal spillage.  This reduced throat velocity can also reduce mill differential pressure and internal mill component wear.  In most cases, we have been able to achieve a reduction in mill motor amp consumption with an increase in the maximum feed rate and coal fineness.

Some of the many advantages of Southwestern's design include:

  • Individually designed for each plant, based on mill operating parameters and maintenance conditions
  • Help to reduce mill differential pressure as part of the design
  • Multi-vane design reduces and controls spillage without higher velocities
  • Does not use deflector liners or require hardened steel or cast liners
  • Fabricated steel, instead of cast, so they are easily installed and maintained
  • Replacement components and full kits available on short-order

We are confident that Southwestern's Rotating Vane Wheel, Throat and Air Port designs will provide you with excellent service and mill performance.  In fact, we welcome any opportunities for side-by-side comparisons with OEM or other manufactures designs.  One of Southwestern's best assets is our commitment to working with plant staff in achieving the best possible results with our equipment.
