GNZJ series mud cleaner by GN Solids America LLC

GNZJ594E-2S12N Mud Cleaner  is the 4 panels screen installed, low buffer box in placed and pair with two Martins 2.5 HP motor.  The control box is met IEC EX, ATEX AND UL explosion proof and certified.  GNZJ594E-2S12N mud cleaner is combination of desander, desilter and shale shaker in one.  The design contains two 10 inches hydrocyclones for desander and twelve 4 inches hydrocyclones for desilter.  It combine 4 panels shale shaker to become mud cleaner has 240 m3/h treating capacity.  The use of the hydrocyclone for the weighted mud is prohibitively expensive (due to loss of barite) and since ultra-fine screens are incapable of handling the entire mud stream, the other kind  of solids removal device is necessary. A unit consisting of both of these devices covers their individual limitations. It is the drilling mud cleaner.  The main function of drilling mud cleaner is eliminate the solid particles whose particle sizes are larger than the barite, and collect the barite in drilling fluid. When the weighted drilling fluid pass the hydrocyclone, a large number of barites in underflow pass the screen, the barites will be returned to cycle tank

GN Solidification Unit:

  1. The cost of treating OBM or WBM is relatively low. No further chemical waste generated in the solidification process.
  2. GN Solidification Unit is pretty convenient to operate and maintenance. Treating capacity can be adjusted easily by using variable speed screw conveyor.
  3. After solidified the OBM or WBM is changed into solid, which can be reused for approved farming.
  4. These solidified waste can be transported conveniently without any spill or leak.

The main component of GN Solidification Unit:

  1. Drill Cuttings Collection Hopper

Drill cuttings are sent to the collection hopper by a screw conveyor, which collect all the cuttings from centrifuge, cuttings dryer and drying shaker. One 10HP screw conveyor is fixed under the hopper to transfer these cuttings to High-shear mixer.

  1. Storage Box

There are two storage boxes: one is to storage absorber, the other is storage cements. Each storage box has one underneath screw conveyor; these two conveyors feed these materials into the high shear mixer.

  1. High-Shear Mixer

The high-shear mixer has a large force to mix all the OBM, WBM or SBM together with absorber and cements. After mixing thoroughly, it discharges the waste in solid. A catching tank can be used to storage and transport them to other places.

GN solidification units are largely used in drill cuttings management. The treating process is continually in worksite. By using different chemicals or absorbers, GN solidification unit can treat different OBM, WBM or SBM.

The GN desilter is perfect to cut down the solids in mud program.

The GN desilter consists of hydralic, manifold and shale shake. the mud prssure may be elvated to 0.25 Mpa-0.4Mpa by sand pump right after the mud is whirled in pyramid by way of side feeder(2?ˉ1/2)of cones volute. the separated solids is drained from the underflow opening. light mud is drained along the middle passage via top.
20 years experiences prove that GN desilter trusty, significant equipment in drilling operation. It’s ideal for use where drilling is likely to encounter solids when the operator is drilling with significant strong particles. The GN desilter is mostly applied to dispose solids of drilling fluid that could include drill solids for instance hematite, galena from drilling-fuild program.
