Description

Purpose of Mill Fans VVSM-2-I

Centrifugal single-inlet mill fans VVSM-2-I are designed for pneumatic transportation of coal dust in fuel preparation systems for solid-fuel-fired boilers using drum-ball mills for grinding. They can also be used in technological lines for metal production at ferrous and non-ferrous metallurgy enterprises. These fans generate high pressure at relatively low capacity and are subject to intensive abrasive wear from coal dust.

General Information about Mill Fans VVSM-2-I

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

Operating Conditions for Mill Fans VVSM-2-I

The fan design allows installation after separators and cyclones and permits an air dust concentration of up to 80 g of coal dust per 1 m3 of air. Operation is allowed at rotation speeds up to 1000 RPM. The maximum allowable temperature of the transported medium for mill fans is 200 °C.

Housing Rotation Angles of Mill Fans VVSM-2-I

The housing of radial mill fans can be rotated from 0° to 270° in 15° increments. Additional stiffening ribs that interfere with angle fixing can be trimmed if needed.
