jet mud mixer

Recently one unit of GNMS-1000D HDD desander plant and GNMS-500D HDD desander unit, one unit of dewatering centrifuge GNLW554E-VFD, three set of mud mixing and storage system, one unit of jet mud mixer are shipping to engineering company.


The HDD/ TBM desander unit are a compact design mud cleaning system, the technical configuration is as below:
Double deck shale shaker with hydrocylones as 2 phase cleaning equipment, the first phase cleaning is coarse solids separation shaker screen, normally we use API 40 or API 60 shaker screen; the second phase cleaning is fine solids separation by desander cone, the solids are drop down to the fine mesh shaker screen to collect more useful fluids. One feeding pump for desander cone are installed on the compact mud tank with electric control panel, cable connection, pipelines and accessories. The cut point of the desander unit is 40 microns. The GNMS-500D desander unit with one unit of desander cone, the treating capacity is 500gpm; GNMS-1000D deander unit with 2ea desander cone, the treating capacity is 1000gpm. The shaker screen installed on first layer and second layer are both composite material frame shaker screen, the screen locking way is by wedges.


The dewatering centrifuge GNLW554E-VFD is used after the desander unit, the separation cut point is 2 microns, it can separate most of the fine solids, the big bowl big volume decanter centrifuge can meet the requirement of big tdewatering capacity, the recovery fluids will be storage at the 3 mixing & storage tank, the jet mud mixer can mix the fluids with powder chemicals to prepare for new drilling fluids, which can be reused to save drilling cost. The pipelines between 3 mud tanks are in parallel connection, so that the jet mud mixer can mix in any tank. Each tank with its mud agitator for better mixing.

Recently GN solids control shipped 4 units of jet mud mixer and 2 sets of vertical cuttings dryer to China drilling company.


The jet mud mixer is a combination of mud mixing hopper and mixing pump with pipelines, valves, control panel all in one skid as a complete mud mixing package, the user can put in on the flat ground and connect it with the existing mud tank by flexible hose conveniently. The venturi hopper working pressure is 0.25 ~ 0.4 Mpa, it can be equipped with proper mixing pump for different mixing capacity, including 320m3/h, 272 m3/h, 200 m3/h, 150m3/h, 120 m3/h, 90 m3/h, 65 m3/h, 55m3/h, 45 m3/h, for client’s different mixing capacity requirement, we will select proper model.
The mixing hopper can be installed on the tank top and the mixing pump installed on the tank skid for better mixing performance. The mixing hopper and mixing pump can be both installed on the tank skid.
The vertical cuttings dryer is ideal equipment for oil based drilling waste treatment system, it works together with decanter centrifuge. GNCD930 vertical cuttings dryer is the most popular model among our drilling waste management equipments. The screw conveyor transfer the drilling waste to vertical cuttings dryer, the discharged solids from vertical cuttings dryer with OOC below 5%, it can be landfilled or for construction industry. If the disposal limit in the client’s country is below 1%, further treatment like TDU should be applied to meet client’s requirement.


The discharged fluids will flow to the intermediate tank, the decanter centrifuge feeding pump transfer the fluids to decanter centrifuge to separate fine solids, the discharged fluids from decanter centrifuge can be reused to prepare for new drilling fluids with mixing hopper.
