GN Supplied Mud Recycling Plants for Asian Client’s Piling Project

Recently GN Company finished production for 8 sets of Mud Recycling Plants, and would arrange final delivery to client’s work site.

GN Mud Recycling Plant is widely used for Bored Piling, TBM, HDD (trenchless), and water well drilling etc., with working capability ranges from 50~3000m3/h.

The Mud Recycling Plant mainly includes Double Mud Shaker, Desander/Desilter, and Centrifugal Pump.
Mud Shaker is used to remove big size of Solids from the Slurry.
Desander/Desilter is used to recollecting Mud for reuse.
Centrifugal Pump is used to pump slurry to Mud Shaker.

GN Mud Recycling Plant Working Procedure as below,

Feeding mud to Shale Shaker from the mud pit. The mud would be feed onto the bottom layer screen of shale shaker (3) through buffer box(2), then the coarse particles would be separated out, while the mud would flow to mud storage tank (4) through the bottom layer screen of shale shaker(3).
The centrifugal pump (5) sucks mud from the mud storage tank (4), and feeds to desander/desilter cone (6) with pressure used for centrifugal separation, the solids/sand would be discharged onto the upper shaker (3) from the outlet nipple of the desander/desilter cone, and fine solid would be separated out. (The screens of Upper and bottom would be different, and the Upper screen’s mesh would be higher)
The mud passed the upper shaker screen would return back to mud storage tank (4), while the clean mud would enter into intermediary tank (7) through desander/desilter cone overflow pipe. The mud in the intermediary tank (7) would go out through outlet pipe (9) or go back to mud storage tank (4) depends on the fluid level in the recycling tank.
In the mud circulation process, there is a fluids level float switch (8) between intermediary tank (7) and mud storage tank (4), it can balance the fluids level in the mud storage tank (4). When mud level is low in the mud storage tank (4), the overflow from the desander would enter into mud storage tank (4) through the intermediary tank (7). When the mud level is too high in the mud storage tank (4), the mud would overflow to the intermediary tank (7) and go out from the outlet pipe (9).

GN HDD System for Australia

In recent days,
GN will deliver to Australia a 500 GPM mud recycling system for HDD.
It is one of GN’s best seller products as the mud recycling system. And 500 GPM
is the most popular configuration among all the available configurations.

As is known to
all, Australian market for the equipments and machines are different from other
markets, because Australia has a even higher standard and more strict rules for
the machine or devices or the environment protection. Some laws and regulations
are even more strict than their peers like USA and European countries.

Although Australia
has such standards, GN Solids Control and GN
Solids Control’s equipments was accepted by Australia. In fact, GN is
the first and only solids control manufacturer who provided to Australia.

Why GN Solids Control?
As a private owned company, GN has no special background or mother company to
be covered with. That’s why the quality is the most important thing. To win a
future and reputation is always what GN does for the past years, and for the coming
years also. Year in and year out, GN has developed from a small company to a
world well known brand.

In domestic
China, there are lots of HDD contractors who buy from GN, and they are giving
repeated orders because they found GN a reliable company with good quality
products. In outside China countries, GN provided to South America, to Asian
countries and to Middle East countries like Saudi Arabia.

When talking
about clients’ countries, we can not let go Saudi Arabia. Before meeting GN
Solids Control, the Saudi Arabia HDD companies only purchased from US brands,
for shakers, desander, desilters and complete
system. But they turned to GN for more cost-effective solutions, maybe at first
they just had a try, because they didn’t believe in some Chinese
manufacturers,. But later GN proved to them that there are high quality Chinese
equipments.

And also, many
HDD rig companies are sourcing from GN to make rig package with GN mud
recycling systems.

Dual Centrifuge mud system for CPP

GN Solids Control have many
production project for CPP from year of 2010. CPP is the largest HDD contractor
from China and engaged in China and overseas market. GN Solids Control compact
mud system and centrifuge is also working in many different jobsite with CPP
teams.

Beginning of this year, we got 4 sets 500gpm mud recycling system for
CPP. Different from former system configurations, this time CPP require 2 sets
variable speed middle speed centrifuge for each system. In this case, they can
recover the barite from used drilling fluids fast. The centrifuge is GNLW452
big bowl middle speed centrifuge with variable speed control panel to adjust
the speed flexible.

Except for 2 sets middle speed centrifuge,
other solids control equipment including:

1) 1 set Mud desanding cleaner GNZJ705-2S, with double deck shale
shaker GNZS705. It is for the first and second stage separation.

2) 1 set Mud desilter cleaner GNZJ705-12N,
with double deck shale shaker GNZS705.
It is for the first and third stage separation.

3) 2 sets mud agitator installed on
centrifuge tank compartment, to avoid drilling mud settle down.

After double checking the whole system, you
can find the HDD mud system with 2 sets shale shaker, 1 set desander assembly ,
1 set desilter assembly, 2 sets centrifuge. The treating capacity is much
bigger and the drilling mud can go to desanding cleaner and desilter cleaner at
same time. The drilling fluids go into this two units via distribution box and
controlled by flange and valves. Generally, the actual treating capacity can
reach to about 800gpm to 1000gpm.

Why Choose GN’s 4 Panel Shale Shaker for Solids Control

Shale shaker is a type of very common
drilling mud solids control in all kinds of drilling projects. As a leading
manufacturer of solids control equipment, GN could provide the shale
shaker and other mud recycling equipment for oil gas
drilling, horizontal directional drilling, water well drilling, tunneling and
piling projects.

The capacities of GN’s shale shaker are
200GPM, 500GPM and 600GPM under the mud condition of density 1.2g per cubic
centimeter, viscosity 45s measured by Marsh funnel viscosimeter and screen of
API 40.

GN Solids Control has a 4-panel screens
shale shaker which is the largest model in GN’s shale shaker product line. This
model could be used at the oil rig site for primary solids control. At the
consideration of easy operation and maintenance as well as the widely accepted
treating capacity, GN made the model of GNZS594E-HB shale shaker to fully
meet the market request.

So, what are the advantages of this model?
Or we say what the features are?

1. Simple structure design of the shaker
deck, the operator could observe the work performance easily. The added extra
horizontal square steel strips at both sides of the deck make the deck much stronger.

2. The 2 vibrators located vertically with
the beam makes there is a longer connecting face which could distribute the G
force uniformly to the whole shaker deck.

3. Hidden design of the lead screw beneath
the shaker deck makes it available to adjust the shaker deck angle while the
shaker is running. The operator only need a ratchet wrench to adjust the deck
angle from one side of the lead screw, the other side would be adjusted at the
same time.

4. To ensure the better sealing
performance, the screen frame was installed a type embedded rubber sealing.
This rubber sealing will not be taken off with the exception of manually
disassembling.

5. Wedge blocks are used to fasten the
screen panels is also a popular method. This makes the exchanging of the screen
easier.

6. Sometimes the shale shaker could be used
as a under shaker of the mud cleaner unit. All GN’s shale shaker will have the
pre cut installation holes to install the cyclone frame. Which means GN’s
cyclone frame for mud cleaner is removable. All cyclone frame, no matter what
capacity, the installation location would be the same.

7. By changing hopper feeder, GN’s 4-panel
shale shaker could be used as a drying shaker for waste cutting management. The
G force is up to 8.
