Magnetic detection with magnetic bars and metal detector

The hygienic regulations require very high-quality rules regarding industrial production lines involving raw ingredients and bulk materials handling.The magnetic detector system is ideal to attract instantly ferrous particles, weakly magnetized or of very fine size. It securely holds them on its bars, keeping unwanted materials out of the final product.
The magnet positioned at the installation inlet and outlet has became a standard for numerous industries to protect the equipment and the production lines.

2 solutions of magnetic detection

- Magnetic bars 

- Metal detector

magnetic detection


Magnetic bars

The magnetic bars helps to wipe out the problem of ferrous contamination improving product quality in numerous industries working with flour, powders, plastic granulates, sawdust etc... These bars are positioned amidst the product flow and firmly holds the ferrous particles on its bars.

3 designs:

- Static (1 ou 2 grids)
The single grid magnetic detector is designed to stop ferrous particles present in the material flow. It works by keeping the undesired material out of the final product. The quick-cleaning magnets are configured for an easy maintenance.
The section can be square or circular.
The stainless steel magnetic separator, made with two magnetic grids placed underneath each other, provides the same advantages as the single magnetic grid but it is more effective due to its special layout; it ensures the quality material of the final product and limits a number of cleaning interventions.

- Rotative grid
The rotative magnetic bars enable the detection of all types of  metals to provide a clean material as well as protect your bulk handling production line. The rods are arranged in a circle which rotates gently agitating the material and maintaining its flow.

- Inline on pneumatic conveying lines
They guarantee (in dry phase) the purity  of bulk materials with optimum decontamination of particles from 20 µm and eliminates ferrous objects.
The magnetic bars are installed on the pneumatic conveying pipes.


Metal detector

This gravity metal detector is manufactured to suit any gravity application. This system is ideal to manage the free-flowing material regardless its location on the industrial production line. When powders or bulk materials pass through the metal detector, the small ferrous contaminants are immedialty separated from the flowing bulk material.
The equipment can be equipped with an automatic waste flange system. It is the optimal solution to control cocoa, coffee, sugar, aromas, fruit and dry vegetables, flour, rice, chemical powders and plastic granulates.

Double magnetic detection bars under silo

Directly set under the storage silo, the magnetic double grids feeds the pneumatic conveying pipeline. To facilitate the daily control of the production line, a magnetic drawer is installed under the rotaty valve with easy access to the magnets. The mechanical design of the drawer ensures high resistance to pressure.
