Description

Purpose of Mill Fans VVSM-1-I

Centrifugal single-inlet mill fans VVSM-1-I 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 from coal dust.

General Information about Mill Fans VVSM-1-I

  • Direct drive
  • Spiral scroll housing
  • Single-side suction
  • Number of blades – 12
  • Forward-curved blades
  • Direction of rotation – right and left

Operating Conditions of Mill Fans VVSM-1-I

The fan design is intended for installation after separators and cyclones and allows an air stream dust concentration of up to 80 g of coal dust per 1 m3 of air. Operation is allowed at speeds up to 1500 rpm. The maximum temperature of the transported medium for mill fans is 200 °C.

Casing Rotation of Mill Fans VVSM-1-I

The casing of centrifugal mill fans can be rotated from 0° to 270° in 15° increments. If additional stiffening ribs prevent angle fixation, they must be trimmed.
