Laboratory sorting system MSX

 

Multichannel scanning system from Comex (MSX series) provides a wide range of test possibilities to characterise and separate different materials. The main function is to characterise analysed particles in terms of their properties like colour, size, shape, texture, density, etc. The scanning results can easily be used to find differences between the particles and define measurement methods as well as sensor types to identify the particles of interests. Furthermore, the defined identification methods can be used to separate such particles into two separate fractions. This information can further be used for industrial scale sorting systems.

Operating principle

The MSX scanning system consists of different sensor types installed at the transport belt, where the particles are transported one by one during operation. The particles are supplied at the inlet window manually by placing them on the slowly moving belt. The particles are transported and analysed by different sensors including:

 

  • Magnetic sensor consisting of an array of induction sensors measuring magnetic susceptibility of the passing material thus building a “magnetic “ image of the analysed particles
  • UV light source and camera analysing the reflectance index of the material surface in the light wave length range of less than 400 nm
  • IR light source and camera analysing the reflectance index of the material surface in the light wave length range of more than 700 nm. Here different infrared ranges can be applied like NIR, SWIR, MWIR, LWIR
  • Visible light source and camera analysing the reflectance index of the material surface in the light wave length range of 400-700 nm. Here different individual light bands can be used by applying various filters in addition to the regular RGB frequencies.
  • X-ray source and detector array analysing the beam passing through the analysed material. This allows identifying the attenuation coefficient of the analysed material and its internal structure
  • 3D camera identifying the vertical dimension of the analysed particles. This can provide additional information about the analysed material in combination with the other sensing techniques.

 

 

 

At the end of the transport belt a simple rejecting flap is installed to divert the analysed particles to two separate containers, when the system is operating in the sorting mode. The containers are equipped with scales, thus both fractions can be weighted online under sorting mode, or each individual particle can be weighted in the scanning mode.
