Description

Purpose of Mill Fans VM #20 w/motor

Centrifugal single-inlet mill fans VM #20 w/motor are designed for pneumatic transportation of coal dust in fuel preparation systems of solid fuel boilers using drum-ball mills. They can also be used in metal production lines at ferrous and non-ferrous metallurgy plants. These fans generate high pressure at relatively low capacity and are subject to intense abrasive wear due to coal dust.

General Information about Mill Fans VM #20 w/motor

  • Direct drive
  • Spiral scroll housing
  • Single-side suction
  • Number of blades – 12
  • Forward-curved blades
