Below is the photo taken in No Dig show held in Zhengzhou, China at GN booth. There are a lot of professional HDD &CBM drilling contractors from China and abroad visit this show. We take a set of 500gpm HDD mud recycling system to attend the show, it is with a new technology:

Hydraulic lifting device, you do not need a crane in the site, you only use the hydraulic device to lift the mud tank first, then drive the truck on top of the tank, then lower down the lifting device, by this way, you can transport the mud tank easily without rent a crane.

Traditional Mongoose PT shaker screen is made of steel frame, composite screens have the following advantages compared with steel frame screens:

Higher throughput, Longer life, Fewer replacements, Lower cost.

The composite screen’s weight is much lighter than steel frame screen, and same with the original HIFLO screen. But the price is also triple more than the steel frame screens. For some of the clients who care the screen replacement time and service life, composite screen will be the ideal choice.

Shale shaker can be utilized in 2 ways for the rig.

1st utilization is for rig solids control system as the first separation equipments, by this way, some of the cuttings with drilling fluids will be separated out. 

2nd utilization is for drilling cuttings separation, they use fine mesh screen to dry the drilling cuttings and separate usable drilling fluids and back to the rig. The drilling cutting shaker also called hi-G shaker.To continue drying the cuttings, you should use cutting dryer.

The left picture is a centrifuge bowl, which is the main component for the drilling fluids decanter centrifuge. It is mainly composed of taper cylinder, straight cone, screw propeller(inside) and collection box. All of them are made of Duplex stainless steel, which is high strength and high corrosion resistance.

And the bearings in big end and small end are made of SKF bearing. Especially the screw propeller of GN centrifuge is protected by Tungsten carbide tiles, not traditional protection way-coated with Tungsten alloy on the surface.

The picture right showed a mini mud cleaner used for Geothermal well drilling. There are 2 mud tanks in the mud system, one is treatment tank, 1 is storage tank. On the 1st treatment tank, there is a GNZS703 linear motion shale shaker, and 2 mini mud cleaner with desander cone and desilter cone separately.

Mini mud cleaner has larger screen area than desander, desilter with small underflow shaker, so the treating effect is better, and its cost is cheaper than mud cleaner with large underflow shaker. It is the ideal equipments for Geothermal well drilling.
