Optical Sorting |
In the field of sorting technology is
divided into two different product groups: Optical
sorting separates products by means of color
differentiations as well as brightness criteria.
Densimetric tables are using density distinctions to
sort pneumatically on an inclined treatment bottom
with vibratory motion
With the opto-electronic sorting
systems and X-ray sorting systems, it is possible to
remove foreign bodies from materials which were
previously not able to be sorted.
Opto-Sort separates products with extremely varied
compositions and color differentiations, which are
difficult to sort, according to brightness criteria,
color characteristics or unit size and achieves a
high level of purity. We have developed various
machine types depending on the application.
Improved exploitation of raw materials, increased
product quality and reduced processing costs deliver
not only a financial but also an ecological benefit.
• Recycling glass (flat and hollow glass)
• Plastic flakes (PET, PE, PP, PVC)
• Different industrial minerals (limestone, talc,
magnesite, refractory materials)
• Rock salt
• Particle size analysis
This technology is used successfully
in many sectors such as the chemistry, wood,
recycling (compost, rubble from demolition work,
aluminum, etc) or the food and drink industries.
The densimetric tables achieve
outputs that surprise clients due to their
efficiency in the separation process. We have a
testing plant available for clients where tests are
performed that, along with its extensive experience,
guarantee the desired output, efficiency and
Dry densimetric separation is achieved on an
inclined treatment bottom with vibratory motion. A
current of rising air crosses this bottom, which has
two effects on the material to be treated:
1. Less dense products float without
touching the base and slide to the bottom part due
to the tilt.
2. More dense products touch the bottom and are
pushed towards the top due to the vibration.
The greater the difference in density of the
products, the greater the grain size bands treated.
US Process Equipment offers two densimetric table
models, depending on the level of severity of the
Used to treat products with low density and medium
grain size. They have a robust design with wear and
tear parts for severe operating conditions. There
are 4 versions depending on their width (0.7, 1, 1.5
and 2.4 m.).
M model. Used to treat
products with a high density and grain sizes up to
80 mm. They have a specially robust design so that
materials such as crushed minerals or metals can be
treated. Three models are manufactured depending on
their width (0.7, 1 and 1.5 m.).
The two models can be supplied with
or without a dust collection system and this can be
via a cyclone or bag filter.
In the case of the M model, an
extractor hood and ducts can be installed to fully
or partially re-circulate the air.
