Metal separator DMR


Metal separator DMR

The DMR type metal separator is designed to detect and automatically remove ferrous and non-ferrous metals from bulk materials in free fall conveying lines. The DMR separator protects process machines against damage caused by metal contamination, prevents production downtime and ensures product quality.

The DMR metal separator is reliable, easy to use and designed for continuous operation. The metal separator has the highest separation efficiency of metal contaminants (magnetic and non-magnetic). The DMR separator meets the requirements of food quality management systems ISO 9001, ISO 22000, HACCP, BRC, IFS.

Applications of the metal separator

  • Metal separation from dusty food products (sugar, coffee, flour, spices, milk powder, breadcrumbs, etc.)
  • Metal separation from fine-grained food products (cereals, pasta, French fries, popcorn, grains, nuts, etc.)
  • Removal of metals from bulk ingredients of pharmaceutical products.
  • Separation of metals from regrind and plastic granulates - protection of extruders and calenders.
  • Separation of metals from limestone flour and construction mixtures.
  • Separation of metals from loose or granulated mineral and chemical fertilizers.

Principle of operation of the metal separator

The tested product moves through the metal detector tunnel. The detector creates a high-frequency electromagnetic field throughout the entire transport tunnel area - no dead zones. The electromagnetic field generated by the transmitting coil induces a certain signal in the receiving coil. The metal contained in the product deforms the electromagnetic field lines generated by the transmitting coil, thereby changing the amplitude and phase of the signal induced in the receiving coil. The received signal is analyzed by the detector's electronic system and converted into a metal detection signal that initiates the operation of a separation unit, which removes the detected metal along with a small amount of the product.
