The Chinese New Year, and a New Goal

Techniqually after 4 Feb., Chinese start a new year 2019, by lunar clender. Though more and more young generation is enjoying the New Year from Januarary. It is still the most important day for every one to go back home for a family reunion. Kind of most important thing, so it does not matter then where ever you are or you will go after this day, to chase your dream, or a dreamed life, in that moment, you belongs to one place, where comforts you in your hard moments.In GN, also many people from far away, gathered here for a dream, attracted by something changes the world,changes the perceptions of bad name of made-in-china. So every year, we have 2 weeks off, and actually after 2weeks, everything start get back to track.

Well great news is:In 2018, It’s a wonderful year for GN. Its revenue in 2018 is 30% higher than that in 2017. Moreover, This achievement was accomplished under three adverse conditions.

    Firstly, the overall international economic form is depressed, and the national economic growth rate has declined sharply.    Secondly, the state's environmental protection policy is extremely strict, and the cost of products increases greatly, which leads to the rise of export prices and the decline of competitiveness.    In addition, for one of the main markets, the US market is also affected by the Sino-US trade war, which makes the export of American products impose a 25% tariff and reduces the competitiveness of GN products in the US market.

And in the new year, plan have been explained by chief Tom Zhou, as 3 H.The first H is Health. In order to provide a healthy working environment for company employees. The company invested about 1.5 million Dollars to build environmental protection production systems in new factories. In the new plant, the company will build a paint production line and a powder coating production line, and equipped with the most advanced VOC purification system. So that the VOC emissions can reach the national standard of 50mg/cubic meter. In addition, for welding and cutting fume, a fume treatment system is also equipped to make welding fume up to the national standard of 4mg/cubic meter. These environmental protection systems not only provide a healthy working environment for company employees, but also assume corporate social responsibility for national environmental protection governance.

The second H is Happiness. The company is committed to support employees to work efficiently and happily. To this end, in software, the company invested more than USD200,000 for online cloud-based ERP system, to achieve boring and repetitive digital statistics and process control through large data and cloud computing. In terms of hardware, the company plans to invest more than 2 million dollars to introduce 12 sets of welding robot workstations. Together with the original CNC processing equipment, paint production and CNC cutting equipment, these will make the production steps of the main processes of the whole company to be in the initial stage of intelligent manufacturing. And the labor intensity of employees is greatly reduced.

The third H is Honor. GN has now provided services to customers in more than 70 countries around the world, we are striving to make our customers break through 100 countries in another three years; Moreover, many of our products have reached the advanced level of our international counterparts, and some of our products are even in the leading position in the world. We will continue to strive to make GN brand comparable to the international first-line brand. Not only should we strive to do a good job in product brand, but also the new factory of GN Solids will provide better living conditions for employees. We will build more than 6,000 square meters of activity venue, so that everyone can live a richer life after work. Through the development of GN Company, we can improve the quality of life of employees, make GN employees proud of GN brand and work together to make GN Company become a “Huawei Brand” in solid control industry.

Stay tune with GN, and welcome join us, or join as a GN equipment user, as your proud of making this choice is always our goal.

Solids Control Equipment Ready for Delivery to India

Before Chinese New Year, before the coming Indian exhibition, now closing off the projects, as usual, though it is a quite busy ending of this year.

The decanter centrifuge and shale shaker are two of critical equipment in the drilling mud recycling system. The shaker removes the coarse cuttings by screen with different mesh size and the decanter separate the fine solids by centrifugal force.

Decanter centrifuge proved to be the best business driven since we moved to the new factory, which is specially for the innovative products, for us, like decanter centrifuge, shaker screens, now centrifugal pumps etc. Every year, got more and more business on decanter centrifuges, including the decanter centrifuges delivered with system, more than 200 units are exported all over the world.

For ultrafine solids, flocculants need to be added into the drilling mud to gather the solids so that the decanter centrifuge could remove that easily. GN also supplies thedosing systemwith tube screw conveyer for chemical powder transferring and blenders for chemical mixing. In consideration of the climate, GN can make the tank skid with roof for sunshade and rainproof.

GN shale shaker is widely used in oil and gas drilling and other type drilling projects. Normally for oil gas drilling, GN provided the shale shakers with explosion proof standard vibrators and control panel for safety purpose. GN has established close business relation with many clients from HDD industry in India. Application in trenchless drilling does not request explosion proof, thus client can choose the non-explosion proof vibrators for cost saving.

Welcome to visit GN yard, and also welcome to meet with us in all the exhibitions we may attend, or exhibit. Stay tune.

Aumina Slurry Dewatering Separation

Check the video:

So if you are not sure about your material, not sure about our equipment performance, we are enlarging our lab to be able to do more tests, in the coming new factory, GN is now building a big labratory. So in near future, more experimentation will be proceeded. Recently a client sent few tons alumina to GN factory, then we simulate the situation, then proceed with the centrifuge. Well end of the story is the client happy with the result, and purchased the centrifuges.

Well if it is hard to send us the sample, what should we do?

Send the sample to the closest lab, and ask them to find out the slurry properties, and something as below will be helpful then.


Or you can list all the info onto a table.


Centrifuge is not like other equipment, we use one place, then we can assure performance in all other places. Except you can confirm it is very similar application, like oil gas drilling, or you are doing hydro vac slurry treatment.

A Feedback of Drill Waste Management System

Recently got a good feedback from DWM site, the client use a one skid waste management system, including vertical cuttings dryer, decanter centrifuge, a very typical skid, small tank, c/w feeding pumps, flushing pumps, and control panels.

The GN Vertical Cutting Dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900RPM with G force to 420G. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation.

GN Decanter Centrifuge is designed for the drilling mud solids control and oilfield waste management.GN VFD drive decanter centrifuge with variable speed allows drilling contracor or mud service company to do the barite recovery, fine/ ultra fine solids separation,dewatering centrifuge.GN have the decanter centrifuge from 9 inch bowl to 22 inch bowl available for different applications.GN decanter centrifuge bowl length and diameter ration is over 3, this gives the best result for the drilling fluids cleaning.

After the equipment, the solids result, and liquid result meet client requirement.

One More Set Solids Control Equipment for Russia Oil Company

Recently, GN just shipped out one more batch solids control equipment manufactured for a Russia oil company. Being a leading manufacturer of drilling mud solids control equipment, GN Solids Control is well remarked in world market for the excellent product quality and onsite performance. More and more drilling contractors and Oil Company came to GN for business negotiation.

The order from this Russia oil company is consisting of main solids control equipment such as shale shaker, mud cleaner, decanter centrifuge and the degasser unit. All equipment is painted customized color that is good for advertising to clients business.

Shale shaker is the first step separation equipment in solids control system. GN shaker is designed simply in the shaker screen installation and shaker deck angle adjusting device. Simple design makes the operators quickly to handle it. Patented sealing rubber installation method and high quality rubber material selection ensures the good sealing performance. Normally, in the same mud system, it is recommended to use same model shaker as the bottom drying shaker of the mud cleaner unit for convenient maintenance in future. GN mud cleaner is composed by the under shaker and movable cyclone manifold. The manifold frame is made with standard dimension and structure for easy assembling/disassembling in transportation or installation.

GN centrifugal degasser unit is with small footprint and installed vertically on mud tank, it can remove the cut-in gas from return drilling mud effectively so as to increase the working efficiency of subsequent centrifugal pump and cyclone unit. GN centrifugal degasser is a self-suction unit without extra feeding pump.

GN 14 inch decanter centrifuge is popular model in drilling mud separation system. The centrifugal casting technology makes the bowl material of the centrifuge denser to avoid the air bubbles so that to get a better dynamic balance. Normally, GN is providing the decanter centrifuge with explosion proof control cabinet, 6 meters feeding hose, solids discharge chute as standard package. For better installation on mud tank, GN always suggest client to choose the extra centrifuge supporting legs.

At the end of year 2018, GN successfully completed the shipment of this batch solids control equipment to guarantee the delivery on client site on time. Wish client a good operation of the project in using GN equipment, which is the best gift to GN in New Year.
