GroTech sorting machines find a perfect application even in mineral
working plants, to sort materials with granulometry between 0 and
GroTech sorting machines analyze product into free fall with
customized cameras, exploiting the latest technologies into
visible, which, combined with LED RGB broad spectrum or neon
(depending on models), allow to achieve an optical resolution of
The most precise ejection system, granting up to 2 billion cycles
and up to 1.000 shots/second, allows to have concentrated and
minimum rejects, even thanks to simultaneous reject resort or
Mechanical design and particular accuracy into preventing machine
from wearing and external agents influences, make GroTech sorters
the most reliable and steady performance machines on market.
If a sorter is required for use on corrosive products, special
versions of the sorter can be produced in Stainless Steel 316L.
The wide variety of machinery ranges and configurations allows
GroTech to offer models having throughput from 500 kg/h up to 45
ton/h, with possibility of production upgrading even after
installation and start-up.
GroTech color sorters are also successful in refined processes such
as rock salt and sea salt and offer the best color sorting for salt
Growking color sorters detection system is able to detect minimum
differences in color and shade, with an optical resolution of
Light or dark grey impurities, such as anhydrite, or with light
orange and brownish shade, such as sulfur or inert or organic
parts, are perfectly detected and sorted with the highest
The possibility to foresee a simultaneous reject resort allows to
recover good product rejected during the sorting phase, due to the
high operating speed.
GroTech sorters grants quality and hygiene safety when sorted salt
is destined to food and non-food consumption.

Features of GroTech Color Sorter
No matter what type of food you're sorting, removal of foreign
material and potentially dangerous matters is critical. That’s why
you need impeccable sensor-based sorting technologies. If you are
curious about what this technology can do for your sorting task,
please contact us.
Sensors are like good eyes. Detection is at the core of sorting.
GroTech’s high-tech sensors are like eagle eyes; they see more and
are thus able to detect and supply more information.
1,Eagle eye vision color sorting technology, using 16 million
colors, brings the best sorting performances
