mud mixing system

Recently one unit of mud mixing tank and 8 sets of mixing pump are shipped to engineering company. The mud mixing tank including 2 round tank with transfer pump, electric control panel with skid, pipelines, valves. The mixing pump and mixing hopper are installed on the skid with pipelines. It is an independent part of mud mixing tank. The mud agitator are installed on top of the mud mixing tank for better agitating and mixing of the chemicals with the drilling fluids.


GN centrifugal pump is interchangeable with world famous brand centrifugal pump, including the bare pump and pump parts. The impeller and pump casing are made of ductile hard iron for better wear resistance. The centrifugal pump can be used as trip pump, mixing pump, super charging pump, transfer pump, feeding pump, etc.
We can design customized mud mixing system according to client’s requirement, normally we design square shape mud tank, the jet mud mixer are connected with mud mixing tank as independent part. Except for mud mixing system, we also produce and design mud recycling system. According to different treating capacity, we have option for 200gpm, 400gpm, 600gpm, 800gpm, 1000gpm mud recycling system. We have 2 phase cleaning, 3 phase cleaning system for mud mixing system, 2 phase cleaning including shale shaker and desilter cone with mud mixing unit, 3 phase cleaning system including shale shaker, desander cone and desilter cone with mud mixing unit.


The mud agitator motor from 3KW to 22KW to suit for different size mud mixing tank, including GNJBQ030-D, GNJBQ055-D, GNJBQ075-DD, GNJBQ110-DD, GNJBQ150-DD, GNJBQ220-DD. The jet mud mixer including mud mixing hopper with different centrifugal pump, we can also install the mud mixing hopper on top of mud tank and the mixing pump installed on the tank skid or the mixing hopper and mixing pump both on the tank skid.

Recently GN solids control shipped mud mixing system to trenchless engineering company, the technical configuration is as below:


One transfer pump installed on one side of the mixing tank to transfer the mixed drilling mud to other place. The mixing hopper and mixing pump installed on the other side of the mixing tank with proper pipeline fittings, the man hole, clean gate, handrails and stairs are equipped on the mixing tank. The centrifugal pump head is interchangeable with famous brand centrifugal pump, the pump casing and impeller are made of hard ductile iron for better abrasion resistance.


The other mixing tank is consist of mixing hopper, and 2 shear mixing pump with its individual control panel, another transfer pump is on another side of the mixing system to transfer the mud. The pump can cut the chemicals into small pieces for better mixing performance of the chemicals, 2 each round chemical mixing tank are located in the mixing skid, with mud agitator on top of the mixing tank and liquid level meter, pipelines, valves, etc. accessories are attached. The painting and coating color is customized as per client’s requirement.


Except for mud mixing system, GN solids control can also produce dewatering centrifuge package to separate fine solids and get water recovery. The dewatering unit consists of one unit of dewatering centrifuge, 1 unit of centrifuge feeding pump, 1 unit of chemical dosing unit, 1 unit of catching tank. GN desander unit for TBM, piling engineering company should be used before the dewatering centrifuge, desander unit including 1ea double deck shale shaker and hydrocyclones ( desander or desilter), feeding pump, transfer pump and catching tank, the function is to separate coarse solids from the slurry, the fluids can be reused or treated by the dewatering centrifuge unit to get clear water.

This week GN solids control shipped 2 sets of HDD mud recycling & mixing system to India client for their HDD projects. This is not the first order from the HDD contractor, they bought the 350gpm mud recycling system and 500 gpm mud recycling system several years ago for their Vermeer rig. The technical configuration is as below:


One mud tank 9000x2300x2150mm which is customized design size to meet their storage capacity requirement. For compact design and better mud cleaning performance, we installed the double deck shale shaker with desilter cones to meet the client’s capacity requirement. A centrifugal pump as feeding pump of the desilter cone, one centrifugal pump as mixing pump for the venturi hopper. The mud agitator and mud gun installed on the mud tank for agitating the drilling mud and prevent the solids from silting. An extra submersible slurry pump is equipped as the feeding pump of the mud recycling system from the mud pit.
Features of the 2 sets of mud recycling system:
1) Compact design with the biggest storage capacity as per the client’s requirement
2) Container loading size for convenient transportation and cheaper sea freight cost
3) Mechanical seal centrifugal pump, the impeller and pump casing material is made from hard ductile iron alloy, increased abrasion resistant capability.


4) Double deck shale shaker with desilter cone for 2 phase cleaning and increase the reating capacity.
5) Pretensioned shaker screens with composite material frame for longer working life and better separation performance.
6) Explosion proof electric control system for better rain proof, sun proof and dust proof.

Right now, in GN head quarter near Beijing, in the ware house, there is a set of oil drilling mud system ready for shipment. This is a drilling mud system for a ZJ50 land rig and it will be used for India Drilling. This is for a complete drilling mud system with all necessary separation phases, the 4 phase of clarification and 5 phases separation.

The equipments in this drilling mud system include following:

  1. shale shakers of 3 sets, they are connected directly to the mud distributors and worked at same time. They are located on shaker tank. Recommended GN shale shaker.
  2. vacuum degasser, it follows the shale shakers and will be used to separate out the air bubbles from the drilling mud, it also plays a role as a big mud agitator and it helps to protect the centrifugal pumps for feeding the desander and desilter and also enhances the working efficiency of the hydrocyclone feeding pumps.
  3. desander and desilter, respectively of 10 inch cyclones and 4 inch cyclones. Recommended GN desander and desilters.
  4. decanter centrifuges, they are used for recovering the barite and for extra fine particles separation.

Besides mud solids control system for oil and gas drilling, mud plant, oil and gas waste management systems for drilling mud and drilling cuttings, GN products also covers the mud mixing  systems for the HDD drilling, CBM drilling, TBM projects and water well drilling. And some of GN clients are using GN Solids Control’s equipment in their industry sludge separation works.

In each year, GN engineer team makes new improvements for the existing equipments and also design and put into reality the new equipments to feed the new standard for the environment protection or the requests from the clients and end users. That’s why GN’s products such as shear pump, Mud Gas Separator , mud agitator , Vacuum Degasser ,etc. and fame are becoming better and better. In the past year, GN has put into use the solidification unit for the oil based mud cuttings and end users from both domestic and abroad give good feedbacks.
