Metal detectors ensure the cleanliness of the material and free it from metallic impurities.

MD Plate Metal Detector
RozwińZwiń
The figure above shows a plate metal detector placed inside the N-CPR conveyor to detect metal contaminants as the material is transferred from the forming device to the mill.
The plate metal detector is also ideal for applications outside of injection molding where there is a near-continuous flow of material that is usually well distributed on the conveyor.

The figure below shows a tunnel metal detector installed on an MB conveyor to detect metallic contaminants contained in large masses of material and/or large-sized products. These solutions are commonly used in the field of plastics recovery..

MD magnetic roller
RozwińZwiń
The magnetic roller is only proposed when the detected metallic contaminants are ferrous and therefore sensitive to the magnetic field.
The roller consists of a series of sector magnets attached to each other and is installed as a drive roller.
Ferrous impurities captured by the magnetic field do not fall into the granulator inlet, but are carried outside and discharged into a chute intended for this purpose.
