GNMS -500GL 500 GPM mud system is a top option for horizontal directional drilling mud system . This is 3 phased cleaning with shale shaker , desander and desilter cleaning . But how this mud system working princedure on Job Site ?

For HDD drilling , when mud from rig out of hole , mud will be guide to a mud pit a mud tank , one set vertical slurry pump will pick up mud and feed to first phase cleaning shale shaker  buffer box though a soft rubber pipe .

The buffer box will reduce mud speed and avoid to much flush of shaker screen , there are 3 decks for shale shaker for first phase cleaning . If installed 40 mesh shaker screen , it will separate solids around 400 microns . The solids particals will be discharged out of shaker by a shaker vibrating and fluids particals will drop into first compartment in recycling tank .

1# centrifugal pump will pick up mud from first compartment and feed desander though pipeline , by a correct pressure , the desander will separate solids around 50 – 60 microns , the solids particals will discharge though desander nozzle and drop onto shaker screen on second shaker , the fluids particals will over flow and drop to second compartment .

2# centrifugal pump will pick up mud from second compartment and feed mud into desilter cyclones , by the correct pressure , solids will be discharge from desilter nozzle and drop on to screens on second shaker , the fluids particals will be over flow and drop to third compartment . Both solids drop onto second shaker , final solids will discharge out by shaker bivrating and fluids recycled into second compartment .

3# centrifugal sit on tank skid for mixing mud in third compartment when need new mud or need add new chemicals .
