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.
