Welcome to Visit GN Booth at CIME 2023 Mining Exhibition

In this hot July, there will be an international mining exhibition to be held in Shenyang City, the largest city in Northeast China. The full name of this Exhibition is CIME 2023, the 3rd Sino-foreign Mining Industry Chain Development Forum, which will be held from July 27th to 29th in Shenyang International Exhibition Center.


GN Separation will attend this exhibition, brining GN Vibrating Machines and other equipment used for mining industry.

About GN Separation: GN Separation is sister company of GN Solids Control, a leading brand in oil and gas solids control industry, which is exporting its products to 80+ countries in the world. GN Solids Control is mainly focusing on the drilling fluids solids control and waste management equipment and systems, while GN Separation covers other industries like mining, water treatment, food and beverage industry. Mining Vibrating Screens and Decanter Centrifuge are quite popular products for GN clients from mining industry.

For this CIME 2023, GN Separation will bring following equipment:


1. Stack vibrating screens. Stack vibrating screens are designed by GN team for wet screening, classification and dehydration of fine grained materials in mineral processing, coal preparation and etc. Two or more screen decks are stacked together, with same deck size and openings. The input material will be divided to each deck evenly and the output will be collected together. There is only one energy source for all decks. This design maximizes the usage of both the vibrating motors and the limited room.

2. Dewatering vibrating screen. Dewatering vibrating screen and classification vibrating screen are two kinds of GN middle sized vibrating screens. Their barriers are not so huge between the two kinds of screens. In fact, some clients are using classification vibrating screens for dewatering applications. But GN dewatering screen is more efficient with a slight modification.

3. Screen panels and screen meshes. The screen panels on the dewatering screen and screen meshes on stack vibrating screens are both manufactured by GN Separation. GN vibrating screen panels are polyurethane covered while GN vibrating screen meshes are fully polyurethane.

Welcome to meet GN team at GN Booth BT05 in Hall E3, from July 27th to 29th.

GN Solids Control System for oil drilling to India Company

Solids Control equipment and system are always the core products for GN Solids Control. As is clearly shown, the Solids Control is the main parts in GN’s company name. Each year, GN designs and sells tens of complete solids control systems to lots of oversea countries. Sometimes, GN makes the equipment sets for a whole solids control system for clients to build up their own mud tank systems in their own facilities. This system is a complete drilling fluids solids control system for a client from India. It is a repeated order from GN old customer.

2023.06.15 Decanter Centrifuge

This drilling fluids solids control system contains following equipment:

1. Double deck shale shaker GNSZ706J. Shale shaker always shows up in the first stage to remove the largest share of drilling cuttings. Comparing with a single deck shale shaker, a double deck shale shaker can increase the treating capacity by 30%. The drilling mud falls onto the upper deck of shaker with comparably coarse screens for the 1st separation, then onto the lower deck with finer screens for the 2nd separation.

2. Vacuum degasser GNZCQ270. A degasser is used to remove the gas bubbles from the drilling mud. It can help to protect the pumps after the vacuum degasser. GN Vacuum degasser has a special design which doesn’t need an additional feeding pump. It is always located after the shale shaker and before the desander and it can also plays the role as a large mud agitator.

3. Desander GNWSJ-2S. This is a desanding unit without underflow shaker. It is fed by a centrifugal pump and is used to remove particles larger than 40 microns.

4. Desilter GNZS752-12N. Desilter cyclones are used to remove particles larger than 20 microns, and it is also fed by a centrifugal pump. This one is equipped with an underflow shale shaker with 2 pieces of screens.

5. Drilling fluids decanter centrifuge GNLW363D. Decanter centrifuge is used to remove the fine particles from the drilling liquid, ranging from 2 to 5 microns.

6. Mud tank system including centrifugal pumps and mixing hopper.

Based on your own standards and requests, GN team can give customized solutions.

GN Solids Control Centrifuge at 2023 NEFTEGAZ Russia Oil Exhibition

The Russia Oil Exhibition NEFTEGAZ 2023 was held by end of April in Moscow, which was a sign of recovery after the three years’ pandemic, the recovery of the whole economy all over the world. As also since the April, China has adjusted the policies for coming in and going out. NEFTEGAZ 2023 was the first exhibition GN has attended after everything is back to normal.

Here is some information about the exhibition:

2023.04.28 Vertical Cuttings Dryer

For this exhibition, GN Solids Control has brought to Moscow following equipment:

1. Solids control decanter centrifuge. In a standard solids control system for oil and gas drilling, the first step is always the shale shakers. And after the shale shakers, sometimes there are desander and desilter cyclones for finer particle removal. But in nowadays, more and more decanter centrifuges are being used after the cyclones. In some cases, end users are even replacing the cyclones with 2 centrifuges, a middle speed one and a high speed one. This time for this exhibition, GN brought a high speed centrifuge.

2. Vertical cuttings dryer. GN has been manufacturing the vertical cuttings dryer from year 2014 and has upgraded its GNCD930 series vertical cuttings dryers for many times. A vertical cuttings dryer is designed especially for treating the drilling cuttings for oil based mud. Those cuttings are generated from the shale shakers’ discharge. After shale shaker, although all large particles are removed, the particles are still too wet, containing valuable drilling fluids. In this case, the vertical cuttings dryers are used for reduce the moisture of cuttings and recover as much fluids at same time.

3. Shale shaker screens. Shale shaker screens are also one of GN Solids Control’s core products. They seem simple, but in fact they are of core technology including the matching of mesh cloth, the strength of frame and etc, which will greatly affect the shaker’s performance. GN is professional in both shale shakers and shaker screens.

Among all the pumps, the vacuum pump is a quite special one and also the most popular one.

1.GN Vacuum Pump is fully air driven, that’s why it is called vacuum pump. It is generated by an air compressor, with a negative force, it can suck in the material. And with a positive force, it will push out the material to a certain distance. It needs no electricity at all, so it is fully explosive proof.

2.GN vacuum pump is also called a solid pump, because it can handle solids particles easily, as long as the particles can pass the pipelines. The material to be transferred need to be liquidate, while liquid is not a must. For example, the sands or small stones can be transferred by the vacuum pump easily.

3.GN Vacuum pump can be used for different applications, including oily sludge industry, refinery, animal waste, chemical transferring, minerals, coal powders and etc.

Clients from different industries are coming to GN for purchasing this pump. That’s why, for the 3 standard models, GN are making stock for quick delivery for clients. Please contact GN team for confirming the soonest delivery time.

A batch of GN Mini Decanter Centrifuges to be delivered to European Customer

Decanter centrifuges are widely used in various drilling industries for the separation of solids and liquid, including the oil and gas drilling, geothermal drilling, diamond drilling and pipe jacking. Based on different requested drilling capacities, there are different sizes of centrifuges for option. This time, for this European customer, GN provided a decanter centrifuge of 9 inch diameter bowl, which is the smallest model among GN Centrifuges.

2023.02.24 Mini decanter centrifuge

1. GNLW223 Decanter centrifuge. It is also called a baby centrifuge among all GN centrifuge models. The length diameter ratio is 3, which is a typical value for drilling mud separation works. The largest RPM it can reach is 4500RPM, and it can efficiently remove all the particles from 2 to 5 microns.

2. Applications of GNLW223 decanter centrifuge. GNLW 223 decanter centrifuge is small but popular. It is widely used among GN clients in diamond drilling projects, geothermal well’s drilling, HDD projects and animal waste treatment. It is a compact model especially in North America and Europe.

3. Special design for this batch of GNLW223 decanter centrifuges. When the centrifuge is put into use, it should be put on a certain height in order to discharge the liquid and solids. That’s why there is always a skid, sometimes telescopic, under the decanter centrifuge. For this batch of decanter centrifuges, GN designed a small tank below the centrifuge, together with half height as the standing frame. The small tank could be a catch tank for holding the discharge liquid. While transportation the solids discharge chute can be folded between the tank and centrifuge. The tank is open top for easy observation and to clean. Near to the bottom, there is a port as drain port.

GN Separation will attend 27th Mining World Russia Expo in April

In the coming April, the 27th Mining World Russia will be held in Moscow. GN Separation will attend this fair, brining GN Mining Vibrating Screen and polyurethane screen panels.

Mining vibrating screens can be regarded as a large group, including several different types. Dividing by size, there are small models, middle size models, and large ones. Based on different structures, there are stack vibrating screens, linear motion vibrating screens and banana screens. Depending on the functions, there are vibrating screens for classification, for beneficiation, for dewatering and etc.

This time, GN Separation will bring to the exhibition a stack vibrating screens and screen panels.


1. Stack vibrating screen’s structure:

Stack vibrating screen is a self-designed equipment of GN Separation. It is called stack, because it can be made with 2 to 5 layers, and the exact layer number depends on the job site requirement because each layer has the same screen size and equipped by exactly same screen opening sizes.

2. Features of stack vibrating screens:

The material will enter each layer equally and to be separated at same time and to be discharged under same condition. And the products after separation are collected together. In this way, the separating capacity is doubled, tripled and even quadrupled in a limited space. It is also economic to use a stack shaker when considering the consumption of energy, cause all those screen layers are sharing 2 sets if vibrating motors.

3. Function of stack vibrating screens:

in fact, all mining vibrating screens are suitable for more than one function as the working principles are same. Stack vibrating screens are mostly used for wet separation, classification and fine grained material separation in a mineral processing.

Along with stack vibrating screens, GN Separation will also bring polyurethane screen panels to the exhibition.
