API SHAKER SCREEN

Mining tailings are the solid waste materials that are left over after mining operations. They can contain a variety of materials, including sand, gravel, clay, and heavy metals. Tailings can be a major environmental liability, as they can pollute waterways and contaminate soil.

One way to dewater mining tailings is to use a decanter centrifuge. Recently, GN has shipped the big bowl decanter centrifuge with the model GNLW764A-VFD for overseas mining tailing dewatering projects.

A decanter centrifuge is a machine that uses centrifugal force to separate solids from liquids. The solids are deposited in a cake at the bottom of the centrifuge, while the liquids are discharged from the top. The GN big bowl decanter centrifuge is the 30-inch (760mm) bowl-diameter decanter centrifuge. with a bowl length and diameter ratio of 4.2:1. This bowl size allows the client to handle big volume fluids with one single unit. The GN big bowl decanter centrifuge is designed for best performance in Tunnel Boring Project Mud Cleaning, Dredging Slurry Separation, and Municipal Sewage Sludge in Purification Plants, and Industry Waste Water Treatment.

GN Solids Control is a leading manufacturer of decanter centrifuges. Besides, GN Big Bowl Decanter Centrifuge is a high-performance machine that is ideal for dewatering mining tailings. This time, we also supplied the dosing system for better treatment, it is mounted in two containers, very convenient for shipping, and the installation process is also simple and can be completed in a short amount of time.

GN is the first API-certified equipment manufacturer in China and we provide quality decanter centrifuges to the mining industry. Besides, GN also supply vibrating screens to the mining separation and shale shaker in the oil drilling projects.

GN ZYQ series drilling mud-gas separator is a special equipment for the primary degassing of drilling fluid, mainly used for the first step in drilling mud treatment. The large bubbles, which with a diameter ≥ φ3mm from drilling fluid that mostly fills a section of the wellbore annulus, could be removed and ignited.

If the expansive gas is not removed, it will easily cause a well kick, and even eject the surface of the drill disc. And sometimes do harm to solids control equipment like centrifugal pumps or agitators or centrifuges.

GN ZYQ series anti-hydrogen sulfide drilling fluid mud-gas separator is made of high-quality materials, which can effectively remove most part of harmful gases to ensure the safe production of personals and equipment.

The MGS has the following characteristics:
1. The separator uses a bottom drainage system to control the height of the liquid inside. This ensures that the liquid level stays constant, which helps to prevent solids from accumulating in the tank.
2. There is a special pipe for gas separation in the MGS, and the gas is emptied smoothly, which improves the gas treatment effect;
3. The mud was pumped into the MGS and drops on a series of inner plates,  an effective way of separation to ensure the gas separation effect;

Then, here is the main technical parameters the GNZYQ 1000A and GNZYQ1200A :

Vacuum pumps are effective equipment for pumping mud, sand, or solids.  GN Solids Control has made and supplied Vacuum pumps for many years, and they are welcomed in Qatar oil tank cleaning projects.

Sludge vacuum pumps work by creating a vacuum in the pump chamber. This vacuum draws the sludge into the chamber, where it is then pumped to the desired location.

 

Sludge vacuum pumps can be either positive displacement pumps or centrifugal pumps. Positive displacement pumps work by moving a fixed volume of sludge through the pump chamber. This type of pump is typically used for sludge with a high solids content. Usually, sludge vacuum pumps are typically used in waste fluids treatment plants, mining operations, and other industries where sludge needs to be transferred.  Contracting with a centrifugal pump, the centrifugal pumps work by rotating an impeller, which creates a centrifugal force that draws the sludge into the pump chamber. However, centrifugal pumps can’t transfer high-velocity mud or solids, or the material will destroy the impellers. Centrifugal pump is typically used for sludge with a lower solids content or water. The main vacuum pumps welcomed in Qatar are the 20B and 40B pumps, which means the 20B can pump 20m3/h and 40B can 40m3/h.

However, sludge vacuum pumps can be noisy and they can have a relatively high power consumption because it must be connected to a pneumatic device to provide an air supply. But it doesn’t need a motor and there is no rotary spares inner the pumps. It is easy for maintenance.

If you want to learn more about the vacuum pumps, please contact me at samuel@gnsolidscontrol.co for more details especially for the mud-treating projects.

GN mud cleaners are usually the second or third-class solid control equipment used to treat drilling fluids. They have complied with a bottom shale shaker, desanders, and desilters.

Let’s take an example of the GNZJ594J-2S12N. It is a compact, three-in-one unit that combines the functions of a desander, desilter, and shale shaker. Made with durable materials, which including polyurethane hydrocyclones, stainless steel bottom deck, and heat-treated shaker deck for longer lifespan. The mud cleaner also features a patented shaker deck angle adjustment system, rubber sealing, and pre-tensioned shaker screens. It is certified to IEC Ex, ATEX, and CNEX standards.

Depending on the size of the cone diameter, desanders are used as second-stage control equipment. They are used to separate solid-phase particles with a size of 47-76 μm from drilling fluids. We commonly use 10-inch cone desanders for this purpose. For desilters, the cone sizes are usually 4 inches which could separate solid-phase with 15-47μm in the drilling fluid.

And for the single deck bottom shale shaker, GNZJ594J, which is popular in oil gas drilling, big trench-less HDD projects, or other industry separation demand.

We can also provide a variety of spare parts for GNZJ594J-2S12N mud cleaner, including cyclones, shaker screens, vibrating motors and other worn parts. (Attention! We don’t supply parts for other brands except for API replacement screens.) We are confident that we can provide our clients with the GN mud cleaner spare parts they need to keep their drilling fluids clean and free of solids. We would be happy to discuss their specific needs in more detail. Please do not hesitate to email me at samuel@gnsolidscontrol.co if you have any questions. I hope this is helpful!

A 3 phase decanter centrifuge is a type of solids control equipment that is used to separate two liquid phases from one solid phase. It works by using centrifugal force to separate the different densities of the liquids and solids. The solids are then discharged from the centrifuge, while the liquids are recycled back into the process.

3 phase decanters are commonly used in the oil and gas industry to separate oil from water and sand. They are also used in other industries, such as the mining and food processing industries.

The solids control system in a 3-phase decanter centrifuge is designed to operate in a continuous manner. The mixture of liquids and solids is fed into the centrifuge at a constant rate by a pump, and the solids are discharged at a constant rate. The control system ensures that the centrifuge operates at the correct speed and that the flow of liquids and solids is balanced.

The efficiency of a 3-phase decanter centrifuge is affected by a number of factors, including the density of the liquids, the size of the solids, and the speed of the centrifuge.

The speed of the centrifuge also affects the efficiency of the decanter. The faster the centrifuge rotates, the more centrifugal force is applied to the liquids and solids, and the more efficient the separation process is. However, if the centrifuge rotates too quickly, it can damage the screw propeller and the rotating bowl. In general, a high-speed centrifuge is designed with a speed of 3000-3500 RPM, which is effective to seperate fluid, oil and solids at the same time.

The discharged mud will be transferred by the auger, the oil will be collected and reused, and the fluid will flow back to the tank, which is mounted with agitators and mud guns Usually, A hopper is also connected to the tank, which is used for making new mud that flows back to the drilling bits and reusing.

The Dubai solids control equipment market saw increased trading activity, as oil and gas companies in the region continued to invest in new drilling projects.

According to industry sources, trading volumes for solids control equipment in Dubai increased in June. The most popular types of solids control equipment traded in Dubai during the month were shale shakers, desander, desilter, and centrifuges.

The increased trading activity in the Dubai solids control equipment market is being driven by a number of factors, including the rising demand for oil and gas in the region.

The UAE is a major oil and gas producer, and the government is planning to invest heavily in the development of new oil and gas fields in the coming years.

In addition, the Dubai solids control equipment market is also benefiting from the growth of the shale gas industry in the region. Shale gas is a type of natural gas that is trapped in shale formations. Shale gas extraction requires the use of solids control equipment to remove solids from the drilling fluids.

The increased trading activity in the Dubai solids control equipment market is expected to continue in the coming months. The UAE is a major hub for the oil and gas industry in the Middle East, and the demand for solids control equipment is expected to remain strong in the region.

The equipment market for GN solids control in Dubai is growing rapidly. GN Solids Control is a leading provider of solids control and waste management equipment for the oil and gas industry.

Shale shaker screens are an essential part of any drilling rig. They are used to remove solids from drilling mud, which helps to prevent formation damage and improve the efficiency of the drilling process.

In the past, there was no standard for shale shaker screens. This led to a variety of screen sizes and specifications, which made it challenging to ensure that the right screen was being used for the job. This could lead to problems such as clogged screens, lost production, and even safety hazards.

API 13C is a standard for shale shaker screens to address this issue. It specifies the physical properties of shale shaker screens, such as the cut point, conductance, and non-blanked area. This ensures that all API 13C-certified screens meet the same high standards, regardless of the manufacturer.

API 13C shale shaker screens offer a number of benefits, including:

Improved safety: API 13C certified screens are designed to prevent solids from clogging the screen, which can lead to a number of safety hazards, such as fires and explosions.

Increased efficiency: API 13C-certified screens are designed to allow drilling mud to flow freely, which helps to improve the efficiency of the drilling process.

Reduced costs: API 13C-certified screens are designed to last longer than non-compliant screens, which can help to reduce the overall cost of drilling operations.

When choosing an API 13C shale shaker screen, there are a few factors you need to consider:

The type of drilling mud you are using: Different types of drilling mud require different screen sizes. For example, water-based muds typically require a finer screen than oil-based muds.

The size of the solids you are trying to remove: The cut point of the screen determines the size of the solids that will be removed. For example, a screen with a cut point of 100 mesh will remove all solids larger than 100 mesh.

The flow rate of the drilling mud: The conductance of the screen determines how much drilling mud can flow through the screen per unit of time. For example, a screen with a conductance of 10 kD/mm will allow more drilling mud to flow through the screen than a screen with a conductance of 5 kD/mm.

Once you have considered these factors, you can choose the API 13C shale shaker screen that suits your needs.

GN Solids Control is the first API-certified shale shaker screen manufacturer in China. The feature of the GN shaker screen are:

Automatic Robot Welding of the steel frame to have better quality and consistency.
