For the upcoming no dig show this September in Australia, GN solids control would like to show there one set self-contained 200 GPM drilling mud recycling system for HDD projects. As a leading manufacturer especially for drilling mud recycling equipment, besides the large footprint mud system for oil drilling, GN solids control could also provide compact structure design mud recycling system.
According to the HDD rig mud flow, GN’s economic mud systems are classified as 150/200GPM, 350GPM, 500GPM, 800GPM/1000GPM and 1500GPM. Just like the unit of 200GPM would be shown in Australia, though it is small footprint, it has all necessary functions for drilling mud recycling and mud re-configuration.

200 GPM HDD Mud System

Below is the equipment list for the 200GPM unit
1. GNZY753-4N shaker and de-silter composition unit which has the functions for first stage primary solids separation and second stage for drying the solid discharged from the 4” cyclones. This unit has a top located buffer box for well back drilling mud feeding, the bottom layer screen of this unit remove the coarse solids, liquid goes through the mesh screen opening and gets down to the storage tank. Pumped by a 15hp centrifugal pump, the liquid was transferred to the de-silter cone for fine solids removing. The upper layer screen with much finer opening would block and separate out the finer solid cuttings.
2. GNSLM20A-110 Jet mud mixer is used for adding the mud chemicals and re-configuration of the drilling mud. The beneath located mud tank was divided into 2 compartments and one of them is used for mixing and storing the active drilling mud. The mixing pump adopted is same with the one for feeding to de-silter cones. That would be much easier for future maintenance and parts replacement. The mixing pump could also be used as discharging pump for transferring the active mud to the rig.

Compact Design Mud System

GN also has more compact unit for de-sanding, by connecting the de-sanding unit with a customized mud tank, the operator could run the mud recycling system more fit their own project condition. For more information on GN compact mud system, you may contact with GN team without hesitate.

As per the feedback from the customers who are engaging in the pilling business, GN designed and perfect the economic mud recycling system specially for the drilling mud cleaning application in piling project. On the consideration of limited location area of the piling project job site, GN’s piling mud recycling system is designed with a very compact structure but with full functions for drilling mud recycling.

De-sanding Unit

Below is the standard configuration of piling mud recycling system with treating capacity of 500GPM.
Model: GNMS500-D
Flow Rate: 500 gallons per minute
Cyclone Specs.: 1 pc 10” de-sanding cyclone made from 100% polyurethane
Screen Specs.: Shale shaker with up and down 2 layers screen with total screen area of 2.23m2
Feeding Pump: Mechanical seal type centrifuge pump of 50 HP used to feed mud to the de-sanding cyclone
Cut Point: Solids Removable down to 40 microns
Catching Tank: Under located catching tank for mud storage. The tank is equipped with lighting system and ladders for easy operation.
Electrical Control System: Explosion, water, and dusty proof electrical control panel with SIEMENS or Schneider components

GN also has the model of GNMS200-D and GNMS1000-D available and the treating capacity is separately 200GPM and 1000 GPM.
The advantage of this type mud recycling system is cost competitive. By connecting with storage tank and mud mixing hopper, this de-sanding unit could also be used in other kind of project like the small horizontal directional drilling, micro tunneling and water well drilling.
