Another great success in DIAMOND MINING!
GET flexy polyurethane screens beat the competition at ALROSA
After the tremendous success at De
Beers Namibia (http://www.get-flexy.com/?case-study&l=us) the Eurogomma’s patented screening
system GET flexy has given another great proof of its value at one of the Mirny
diamond mines of Alrosa (http://eng.alrosa.ru/), the World leader in diamond
When Evgeny Goryunov, the technical
Director of the ore dressing plant N.16 of Nyubirsky GOK, part of the Alrosa
diamond mining group, was contacted by Anna Bruy, the Sale Manager of Eurogomma
Russia, with the information that Eurogomma could offer a screening product giving
guarantee of non-blinding and high productivity with every kind of material he
could hardly trust her words.
So, he took a very reasonable
He called Eurogomma into a trial to
prove the value of our unique GET flexy screen panels.
The trial was a success giving
complete satisfaction to Mr. Goryunov and here we are to let you know about:
Material type - concentrate of heavy medium separation, milled kimberlite
Max feed size - 6 mm.
Hour tonnage - up to 2 tn/h.
Bulk density 3.1>3.4 tn/m3
Screen deck parameters: 830x3000mm – 0° inclination
Screening apertures characteristics: 2,8mm Superflow design
Problem before us: the apertures of standard PU panels from
another Supplier were blinded with sharp stones. This problem translated into screening
efficiency reduction and caused loss of ferrosilicium with consistent overflow.
The benefits offered by GET flexy: the problem of blinding is almost disappeared
and as a result the client has increased screening efficiency and reduced the ferrosilicium
In fact the output has
increased of more than 20% and +3mm material under the deck has reduced from
0,385% to 0,018%
Additional benefits of GET flexy:
1. No more maintenance to clean the deck and release the stuck stones from
the blinded apertures saving time and avoiding production stops.
2. Replacement of our GET Flexy screen panels is easier than the previous
system and this is very important considering the space-limited environment
on the screen deck.
Please link to the client internal protocol to see some pictures of the
test and learn the technical details at http://www.eurogomma.com/documents/Alrosa%20-%20internal%20protocol%20about%20the%20screening%20efficiency%20of%20the%20GET%20flexy%20system.pdf
We want to express our
gratitude to the Alrosa mining group and to Mr. Evgeny Goryunov in
special way to have given us the chance to prove our value.
Our compliments go to Anna Bruy having the
determination, ability and skills to propose a new revolutionary product to her
clients. Good job Anna ;)
