Magnetic plate separator (SPM)

In brief

• The magnetic plate separator (SPM) retains ferrous contaminants from a product flowing between magnetic plates.
• It is used to purify sugar, salt, flour, coffee, cereals, animal feed, wood chips, sand and plastic granules.
• Cleaning is carried out by opening the quick-release fastening system to remove the captured particles.

Applications

The magnetic plate separator is used in several sectors:

• Removal of metal contaminants from sugar, salt, flour, coffee, milk powder, spices, pulses and other bulk food products.
• Magnetic separation of cereals, animal feed and food additives.
• Purification of wood chips, shavings, sawdust and wood dust.
• Purification of gravel, sand and mineral flour.
• Purification of plastic granules.

Operating principles

Operating principle of our magnetic plate separators :

• The contaminated product passes through the separator inlet and reaches a specially designed baffle that distributes the product flow evenly over the magnetic plates.
• Ferrous contaminants are attracted and retained by the magnetic plates.
• The purified product continues to flow towards the outlet.
• Easy cleaning: simply open the quick-release fastening system to remove the captured particles.

Operating recommendations

Recommendations from our Lenoir-Mec experts:

• Install the separator in free fall for optimal sorting without blockage.
• Clean the magnetic plates regularly to maintain a high level of efficiency.
• Choose the right version: ferrite for larger contaminants, neodymium
  for fine metal particles.
• Monitor particle build-up to avoid saturation and loss of efficiency.

Frequently asked questions

What is the SPM magnetic plate separator used for?

It removes ferrous contaminants from bulk products: sugar, salt, flour, coffee, milk powder, spices, cereals, animal feed, wood chips and sawdust, gravel, sand and plastic granules.

How does the SPM work?

The contaminated product enters the separator and a baffle distributes the flow evenly over the magnetic plates. Ferrous contaminants are retained on the plates and the purified product continues towards the outlet.

How do you clean the magnetic plate separator?

Simply open the quick-release fastening system to remove the captured particles. It is recommended to clean the plates regularly and to monitor particle build-up to avoid saturation and loss of efficiency.

What are the technical specifications of the SPM?

It uses ferrite or neodymium magnets up to 6000 Gauss, with an inlet diameter of up to 500 mm. It withstands an operating temperature of up to 150°C and a working pressure of up to 0.8 bar, with a 304L stainless steel housing compliant with food-grade standards.

Should ferrite or neodymium magnets be chosen for the SPM?

Ferrite is recommended for larger contaminants, neodymium for fine metal particles. The separator must also be installed in free fall for optimal sorting without blockage.
