500GPM is the most popular capacity mud system for HDD, CBM and other trenchless activities. GN Solids Control dispatched a 500GPM mud system to clients.
Firstly, remove the shaker box locking device of shale shaker GNZS703E-HB and mud cleaner GNZJ703E-D8N (Please refer shaker user manual and mud cleaner user manual for detailed operation). Then have a trial operation to shale shaker and mud cleaner.
All valves for pipelines are on off state after dispatch from the manufacturer’s factory. Before start up the system, operator should open values first and ensure all of them unblocked.

Then, start up shale shaker GNZS703E-HB and mud cleaner GNZJ703E-D8N. After the shaker and mud cleaner is running stably, start up submersible slurry pump to feed for the shale shaker. It is the first stage separation. When the mud reaches to three quarters of the 1# compartment underneath shale shaker (about 1 minute), start up the desilter feeding pump (1# sand pump GNSB6x5A-12J). Mud will be transferred to the mud cleaner 4’’ desilter cyclone from the 1﹟compartment, at a pressure of 0.25～0.40MPa. It is the
second stage separation. The clean mud from 4’’ desilter cone flow to the #2 compartment. When the mud height reaches to the overflow pipeline, it will overflow to #3 compartment. The user-owned mud pump is connected to the suction line of the 500GPM mud system tank and transfer qualified mud to wellhead. The clean mud can also directly flow to outside storage tank through the desilter output pipe.
When needed, users can start up the mixing pump (2# sand pump GNSB6x5A-12J) and feed to the mixing hopper GNSLS35A. The weighted mud from mixing hopper flows to 3# compartment. The suction port and discharge port of mixing pump are equipped with T-pipe, it can also mixing/discharge mud from/to outside tanks.  
Pay attention to the performance of the desilter cyclone. Ensure it works properly. If not, adjust the cyclone adjustment cap for a better performance. Pay attention to the figures on the pressure gauge of desilter cyclone, ensure it is under the scope of the working pressure. The working pressure of 4’’ desilter cyclone is 0.25～0.40MPa.

Mud agitator is a
motorized mixer that is installed on the storage tank to keep fluid
consist mixed with additive and avoid separation by gravity.  According to the experience of continues use
on the field, the selection of mud mixer should consider to a few points:

1.   
Rotation speed: Operators it does not want the cuttings in the mixing process
splintered more into smaller debris, so the stirrer speeds cannot be high, the
energizer should choose between 50~60rpm. For more than 60rpm of mud mixer,
recommended the user to take a cautious on the result of the high rotation
speed.

2.   
Sealing: According to the feedback of use from the operator.   As mixing conditions are not ideal, the
drilling fluid mud agitator shaft is not suitable for the use of end face seal,
the general packing seal is also hard to use. At present, the more suitable is
the use of multiple sets of V type packing. It has self sealing performance and
self compensation ability, and long-term maintenance adjustments abilities will
not cause lubricating oil leakage problems.

3.    The impeller:
There is a variety of mud mixer impeller, but it must take consideration
that  a small diameter of the blade with
high speed of mixer motor have the small amount of circulation, shear force,
and therefore does not apply to the use of drilling fluid solid suspension.
Therefore, the diameter of the impeller should be consider larger. Second, pay
attention to the turbine type impeller has been widely used in the drilling
fluid mixer, which is the best open type turbine, because there is no central
disc, not to hinder the mixing of the upper and lower liquid phase of the
impeller.

GN
Solids America LLC manufacture its own mud agitator and export it to the
world as needed.
