Product Details


GroTech sorting machines find a perfect application even in mineral working plants, to sort materials with granulometry between 0 and 25mm.


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 0.1 mm.


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 reverse-sorting.


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 solution.


Growking color sorters detection system is able to detect minimum differences in color and shade, with an optical resolution of 0.1mm.


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 efficiency.


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.
