API SHAKER SCREEN

The GN Dewatering Decanter Centrifuge, characterized by its distinctive 8.5-degree beach angle, stands as an exceptional solution for dewatering applications. Primarily employed for industrial wastewater sludge, this centrifuge has a design geared towards easy mud separation. It effectively handles a spectrum of challenges, encompassing large particle sizes, significant density disparities between solids and liquids, low viscosities, high concentrations, and robust treatment capacities, all while delivering enhanced dryness and good clarity. When dealing with sludges or wastewater laden with fine particles, the inclusion of flocculants assists in aggregating these particles, subsequently facilitating efficient dewatering with the Dewatering Decanter Centrifuge.

This decanter centrifuge finds versatile applications across a diverse range of materials, including drilling mud, sewage, cutting(especially water-based mud), and others. It addresses the dewatering needs of intricate substances such as sludge and wastewater. To optimize the dewatering process, the centrifuge capitalizes on its distinct features and advancements.
One of its notable features is the 8.5-degree beach angle, extending the cone section and thereby augmenting the drying and dewatering zones. Constructed with advanced materials like duplex stainless steel SUS2205 or SUS2304, the shaft caps and bowl ends outperform traditional alternatives. The utilization of centrifugal casting and die-forging processes ensures durability by mitigating intergranular corrosion and residual stress issues. The CNC spiral blade forming equipment is employed to press the screw blade, offering superior slag-conveying efficiency compared to traditional methods.
Further enhancing efficiency, the screw blade’s design can be tailored to specific material properties. Additionally, an optimized beach angle, pitch, and the inclusion of a BD baffle plate segregate the dewatering and sedimentation zones. This design fosters clearer and drier separated liquid, while also reducing energy consumption. A double cone design suits high-concentration and high-viscosity materials, bolstering slag discharge resistance and increasing treatment capacity.

Furthermore, wear-resistant components like the tungsten carbide sleeve at the solid discharge port and user-friendly features such as adjustable overflow weir plates and gas spring-assisted collection box covers contribute to the centrifuge’s overall durability and ease of use. These features, combined with innovative bearing designs and machine monitoring systems, position the GN Dewatering Decanter Centrifuge as a reliable and efficient solution for industries grappling with complex dewatering challenges.

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 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.
