For the mining, GN have made a few customised
design systems, the first one is for Turkey, the customer co-design the system
with GN; then for the coring ming project, we design a very small mud recycling system for diamond drilling; then some decanter centrifuge with different layout for mining water; now another customised
system for Philippine mining project.
This system
contains a shaker, two centrifuges. The problems brought to us is: deep
underground, have mining water, with mixtures, different particles, which
destroys the pump which keep pumping the waters out to keep it able to work
there. The pump is made in German, good quality, but also expensive, we want to
keep it operating in good condition, and not easy to get spare parts. To sum
up, we need another system to make the pump running perfectly.
Then we tried
many different choices, to keep it under ground, or keep it on top of the land.
To only use a centrifuge, or use many centrifuges. And questions keep coming
like do we need shale shaker, do we need desnader and so on.
With the
professional help from clients’ engineer, we finally confirm the design, and
also modify the present operation flow of the mining water. Then finally purify
the singing water, then transport to the surface. Since the purpose is not for
drinking, so do not try.
Also in the
system, it contains two Nemo pump, which is made by German Netsch.
Specifications
of decanter centrifuge
we have VFD control panel to achieve stepless bowl speed adjustment to enhance mud treatment
performance
we use Duplex
stainless steel SS2205 for centrifuge casting to improve bowl balance,
centrifuge balance, as well as get better performance on corrosion resistance.
We use
Tungsten carbide tiles protecting the screw conveyor impellers to enhance the
performance when treating heavy mud.
When the
system arrive the site, GN engineers will go to the site for the first time
commissioning and also operator training. To make sure all goes well and in the
right way.
