GN Solids Control is an expert in mud system for tunneling. Just a week ago, GN delivered a set of mud system with dewatering unit to a Singapore customer. Besides, mud system for tunneling, GN also provides mud system for HDD, solids control system for oil and gas drilling.

Dewatering unit is equipped to separate extremely fine particle in the drilling mud to lower the proportion, thus ensuring the high performance of drilling fluids.

 Sometimes, we do not need dewatering unit for the processed mud with particles over 5 microns being removed out is satisfying, but if not, we need this unit to separate finer solids out to meet the requirement for drilling, that’s why we need it in this system. This dewatering unit is a suitable solution.

 GN Dewatering Unit Configuration as below:

1. Coarse Solids Separation System
GN’s dewatering unit is specially for drilling project, thus before the dewatering unit, there is a 2-stage drilling mud recycling system including 1 unit GNZS705-HB shale shaker with double layers screen. And 1 unit GNZJ703E-3S desander unit. With the two equipment, large size solids are removed out.

2. Two Tank Compartments PAM Mixing Unit 
GN’s PAM mixing unit has adopts 2 tanks design with a pre-mixing tank on top. The flocculate dry powder is added from the hopper on tank top and then delivered to pre-mixing tank. As per the response from the level gauge located in either mixing tank, the pre-mixed chemicals would flow into the mixing tank for full mixing and storage. All process here for chemicals mixing is automatically controlled.

3. Dewatering Decanter Centrifuge. 
Used as dewatering centrifuge, GNLW553G separates flocculated colloidal particles. There are two screw pumps, one feeds flocculants to the centrifuge, one feeds active mud to centrifuge. The two feeding process are done at the same time, so the unltra fine solids will be flocclulated larger and then separated out.

Composed of the three main parts, GN made mud system will enjoys a high performance.

30% Discount for GN New Decanter Centrifuge

As an expert of solids control equipment and waste management equipment, Hebei GN Solids Control Equipment is specialized in designing, manufacturing and exporting decanter centrifuge. Decanter centrifuge not only can be used for solids control equipment as the final stage to separate particle with a diameter less than 10 microns, more specific, 2 to 5 microns, but also can be used to purify mud discharged from vertical cutting dryer in a drilling waste management system.

GN Solids Control now has one set of NEW decanter centrifuge GNLW454G on sale with 30% discount. Only one is on sale, and this one has been manufactured and tested, and now in a ready station for delivery to all over the world. The main parameters of this new decanter centrifuge is listed blow.

It has a bowl size of 18inches (450mm) with a draw ratio about 3.7 to 1, it bowl length being 67 inches(1720mm). The bowl speed is 2200 RPM or 2500 RPM depending on different pulley, producing a maximum G force 1573G. Treating capacity of this new decanter centrifuge is 60 cubic meters per hour. And the main motor is 45kw, the back drive motor is 15kw.

So Why GN makes such a discount for a new decanter centrifuge? The main reason is that GN has stopped the production of GNLW454G decanter centrifuge, and replaced it with GNLW454-VFD series decanter centrifuge,which have the same bowl diameter,but have shorter bowl length and high speed, and they produces a high G force. While there is no need to worry the after sales service once you buy it, because the core technology is the same. And the wearing spare parts are also same, so you can still purchase wearing spares part from GN solids control.  Only one is on sales, hurry up!

A Customer from Singapore Came to GN Solids Control to Test GN                           Shale Shaker before Deliver

GN Solids Control  is a leading solids control company specialized in designing an d manufacturing solids control system&equipment and drilling waste management system&equipment. Shale shaker, as the primary and indispensable stage of solids control equipment, how it performs will bring a great impact on the further processing of drilling mud, and even decides whether the complete solids control system will success or not.

Last Sunday, one of our customers from Singapore came to China for a check on the GN shale shaker he has purchased before delivery. Being accompanied with for this business trip is a real benefiting experience. We have arranged him to GN Factory for two objectives. The first one it to make a complete presentation on GN product and project she has designed and build for more than 60 countries all over the world. The second objective is to test GN shale shaker to assure him before delivery. It is glad to say that both of the two objectives has been achieved. Firstly, the customer showed great interest in GN products and proposed many a questions during the presentation. And then we took him to our workshop and tested the shale shaker before him. Definitely, the shale shaker operates excellently during the test, and the customer was extremely satisfied with it. After he came to the hotel, he reported the testing results to his office and the balance was payed.

Actually, GN shale shaker has the following benefits:

1. Shaker deck bottom(screen bed) adopts ss316L, which is more stronger and anti-abrasive, thus the shale shakers will enjoys a long service life.

2. The whole shaker deck enjoys a better stability after heat-treated, thus it can operates for a long consistent time under high G force.

3. The shale shaker adopts patent tighten sealing of shaker and wedged locking system of screen, so it is faster and easier to get screen replaced.

Through a few years evolving, GN has achieved many a the first. GN is the first API certified manufacture of solids control equipment in China; GN is the first manufacture in China who is able to design and manufacture vertical cutting dryer and high G dryer shaker. As an expert in solids control and drilling waste management, GN is striving for more firsts.

Recently, a unit of cutting dryer system for drilling waste is completed in GN. It is specially designed for a Cyprus client. This cutting waste cutting dryer system is composed by the following equipment.

1. One set of vertical cutting dryer with PLC control panel available. The cutting dryer’s speed varies from 0 to 900 rpm.

2. One set of screw pump, which is used to flushing screens inside the vertical cutting dryer to avoid blocking.

3. One set of submersible slurry pump, which pumps the mud to the decanter centrifuge to remove the ultra fine solids out.

4. One set of decanter centrifuge with the typical treating capacity of 132 GPM. The speed of this decanter centrifuge can be adjusted from 0 to 3200 rpm.

5. Removable mud tank for vertical cutting dryer, decanter centrifuge and mud collecting tank.

As to the working process of this cutting dryer system for drilling waste, it mainly includes the below three.

1.Waste cuttings discharged from shale shaker and mud cleaner will directly be transferred to the vertical cutting dryer through screw conveyor.

2.While being processed by the vertical cutting dryer, solids will be discharged from the bottom gate of this cutting dryer and the liquids will flow to the collecting tank.

3.The submersible slurry pump will transfer the mud to decanter centrifuge for further process and particles over 2 microns will be separated out.

GN’s vertical cuttings dryer is suitable for both the OBM and WBM, please click below link http://www.gnsolidscontrol.com/video/vertical-cuttings-dryer-water-based-mud-drilling-waste for video on the vertical cuttings dryer performance.
