The Spanish company is a sensor-based sorting specialist in a wide range of waste material sorting solutions, including optical sorting.
They are looking for metal detection solutions for the separation of ferrous and non-ferrous materials in a same stream, and, subsequently, in a different machine, for the differentiation of two or three ferrous materials and three or four non-ferrous materials.
The inductive sensoring solution is to be integrated in existing equipment of the company that currently provides only machine-vision sorting solutions.
The Spanish company manufactures two types of sensor-based sorters in terms of the particle-size of the materials to be sorted: particles from 2 to 50 millimetres and particles from 50 to 300 millimetres. The width of the sorters varies mostly from 1 to 2 metres, until 3 metres. Most of the materials to be treated correspond to municipal and industrial wastes, after-shredder residues (ASR) of end-of-life vehicles (ELV), electronic waste (WEEE), etc.
Figure 1 shows the combination of inductive detection and machine vision technologies of different equipment, for small or large particle-size materials, that the Spanish company is developing. The inductive sensoring solution sought corresponds to the technology described with “number 3”.
In a first working scenario, the inductive sensors sought must detect the ferrous and non-ferrous particles contained in a wide range of mixed waste streams consisting of different amounts of metal contents, plastics, glass, etc. In a second scenario, the inductive sensors must differentiate mostly iron and steel of the ferrous stream. In a third scenario, the inductive sensors must differentiate mostly aluminum, copper, stainless steel, brass of the non-ferrous stream.
The company is interested in a technical cooperation agreement or a commercial agreement with technical assistance with solution providers in order to integrate the inductive sensoring solution in the current machine-vision equipment manufactured by the company.
A team of highly skilled engineers of the Spanish company will technically support the solution providers with the integration of the technology in the company equipment.
Even if a ready-to-use solution is preferred by the company, the solution may also correspond to a joint development of the provider with the Spanish company.
