Desander Plant and mud dewatering centrifuge for China Engineering Company

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.
