Magnetic Separators

The FLSmidth Ludowici Wet Drum Magnetic Separator (Licenced from Malvern Engineering) is a user-friendly Low Intensity Magnetic Separator.

Magnetic Separator
  • Overview
  • Customer Benefits


With ease of operation, strength and durability, FLSmidth Ludowici’s design offers the best for the recovery of magnetic susceptible material from non-magnetic susceptible material.


Ludowici Magnetic Separators Are Ideal For:

  • Primary applications with high efficiency and high concentrate
  • Hard rock applications (drum sizes from one to three metres long in 0.9m or 1.2m diameter)
  • High non-magnetics loading
  • Magnetite and ferrosilicon in dense media application

The main customer benefits of the FLSmidth Ludowici Magnetic Separators are:

Ease of Operation

  • Revolutionary counterweight orifice design for ease of operation and reduced magnetic losses
  • Innovative tank design allows visual inspection of the overflow and ease of sampling
  • Drum assembly can be adjusted in both vertical and horizontal planes while in operation
  • Drum assembly can be lubricated while in operation
  • Removable trash screen is fitted for easy cleaning



  • A high efficiency and high magnetic concentrate
  • Large arc magnet for increased efficiency
  • Recovery up to 99.99% in primary applications
  • Concentrate densities of between 2.3 to 2.7 (Magnetite) and 2.9 to 3.6 (Ferrosilicon)
  • Low maintenance


Strength and Durability
