The Prospectors' Team Krivbass LLC developed the trammel that was based on the GIT-72 unbalanced-throw screen and provided sand sluicing to 20 ths. cubic meters per day. In 2016, 12 industrial units PGSh-II-50 were in operation on the Proletarsky site. The two GIT-72 based industrial units were mounted and replaced 12 industrial units PGSh-II-50. This provided for substantial energy saving, as well as material and technical saving in production operations.
The screen GIT-72 by Mekhanobr Tekhnika is very reliable, there have been no complaints in its operation. In 2017, another 6 screens GIT-72 by Mekhanobr Tekhnika were purchased, mounted and commissioned that made it possible considerably to increase the annual gold production.
