Drilling Mud Mixing System for Trenchless Engineering Company 

Drilling Mud Mixing System is widely used for trenchless drilling machines. As during drilling activities, they will continually need to use drilling mud to cool down the drill bits, for lubricant, and for bringing the drilling cuttings, rocks and sands out of the hole.

Based on different sizes trenchless machines, different sizes and different capacity mud mixing unit will be used. Recently, some sets of drilling mud mixing units are ready for shipment. After final inspection, the mud mixing units will be shipped to various clients to support for their trenchless activities.

Mixing unit

GN Solids Control offers explosion proof outdoor application control cabinet for all GN systems to offer one-stop solution to users.

GN high quality centrifugal pump is used in the mud mixing unit. The pump can be used as mixing pump, as well as transfer pump and water pump. 4 inch and 6 inch are optional to suit for clients request and to meet various mixing capacities. Tank size and tank capacity is customized per to meet clients request.

For big trenchless machines, or in the countries where have strict regulations on environment protection, besides drilling mud mixing system, the users also need to equipment drilling mud purification system to treat the dirty drilling mud and to reduce the solids and liquid waste which generated from the drilling activities. Shale shaker, mud cleaner, desander, desilter, decanter centrifuge, and sometimes, even dewatering unit will be used in drilling mud treatment system for trenchless machines.

Trenchless refers to the use of various rock and soil drilling machine, drilling rigs to excavate a very small part of the surface (generally refers to the small area excavation at the entrance and exit) through directional, directional drilling (HDD drilling), etc.. Trenless machines are used used to lay and replace pipelines, to make tullling, under sea tunneling, etc…

The new construction technology of repairing various underground pipelines will not hinder traffic, will not damage the green space and vegetation, will not affect the normal life and working order of shops, hospitals, schools and residents, and solve the problems of traditional excavation construction on residents’ lives. Disturbance, damage and adverse effects on traffic, environment, and surrounding building foundations, so it has high socio-economic effects.

3 Packages of GN Dewatering Centrifuge Unit for Europe Client

GN Solids Control makes some high speed decanter centrifuge package for an European client. The high speed decanter centrifuge will be used for dewatering treatment.

The supply scope of the dewatering centrifuge package including following items:

GNLW224EP-VFD decanter centrifuge

1) It includes 3 ea GNLW224EP-VFD decanter centrifuge. It is a 9 inch bowl mini size decanter centrifuge, and it is also the smallest centrifuge model made by GN Solids Control.

GN Solids Control 9 inch decanter centrifuge is widely used for Industry Waste Water Treatment and for Diamond Core Drilling Fluids Treatment. The max. speed of the 9 inch decanter centrifuge is up to 5000GPM, and the typical speed can reach up to 4500 RPM. A VFD control panel is equipped for the high speed centrifuge to adjust the working speed from 0 to 4500 RPM. Clients can choose the suitable bowl speed and conveyor speed per material situation and to reach the best separation performance.

dewatering tank

2) 3 packages of dewatering tank. The centrifuge feeding screw pump is equipped on each tank for compact design. The wetted parts of the feeding screw pump is made from wearing resistance material for long lifetime. The tank package can also be used as Dilution tank and self-priming centrate pump for the high speed decanter centrifuge.

chemical dosing unit

3) A chemical dosing unit is equipped for the 3 ea high speed decanter centrifuge and the 3 dewatering tank units. All tanks, pipelines and internal plumbing are fabricated from 304 Stainless Steel. The chemical dosing unit is equipped with necessary dosing pumps, backup pumps, stainless steel agitators,Screw Conveyor for feeding powder chemicals, etc…

The chemical dosing unit capacity is designed and made to supply chemicals for the 3 decantering centrifuge unit. When the feeding screw pump suck slurry from the tank, chemical dosing unit will enhance chemicals into the feeding pipe. Slurry and chemicals will mixing and react at the feeding pipe before enter into decanter centrifuge.

Applications of GN drilling mud processing system

GN Solids Control makes full line drilling mud solids control and drilling waste management equipment. In this case, GN Solids Control is capacity to make full function Packaged Mud System. Compared with other solids control suppliers who are only capacity to make a certain of separation equipment, GN Solids Control is more professional to make full function package drilling mud treatment system.

Drilling Mud recycling system

Applications of GN Solids Control mud recycling system covers but not limited to below fields:

Oil Drilling Solids Control System. A full set high pressure high temperature drilling mud mud system norally includes 4-stage solids control equipment, plus vacuum degasser or centrifugal degasser for 5-stage separation. 4-stage solids control equipment includes shale shaker, desander, desilter, decanter centrifuge.

HDD & CBM drilling & geothermal well drilling mud recycling system. HDD & CBM drilling mud processing system normally includes shale shaker, mud cleaner, mud agitator, transfer pump and mixing pump. In some case, decanter centrifuge will be used for dewatering treatment in HDD and CBM mud processing system. It depends on clients’ request.

Bored Pile and TBM slurry separation system. It is more popular called as desanding plant. As the mud from bore pile and TBM drilling with big size solids and big capacity flow. Normally only coarse separation shale shaker and desander will be used in Bored Pile and TBM slurry separation system. The shale shaker and desander are fixed on a small footprint mud tank and equipment with feeding pump, transfer pump and control system on the system tank.

Mud recycling system

Drilling waste management system. It is used after oil and gas drilling mud solids control system for zero discharge at rig site. While used together with drilling mud solids control system, people call it as pitless system.

Mining and industry solids and liquid separation system. The mud flow from Geological exploration core drill slurry separation system. Mud from Geological exploration core drill normally not big, but with big percentage ultra fine solids, mini size shale shaker GNZS752 and mini size 9 inch decanter centrifuge is widely used in this application.
