Shale Shaker

A shale shaker is a crucial equipment used in the drilling industry, particularly in the oil and gas sector, during the process of drilling for hydrocarbons. Its primary function is to separate and remove large solids from the drilling fluid or mud, which helps in maintaining the drilling fluid properties and preventing damage to downstream equipment. At GN our shale shakers have OLI or US Martin brand vibration motors and our control panels with Siemens or Schneider Components. We have prementioned composite frame screen with gear unit for fast screen change and longer screen life. The heavy duty design and heat treatment for the shaker basket to get the adjustable G force up to 8.0g. Our shale shaker has an adjustable deck angle, and can be adjusted while working. Here are some parts and important information of shale shaker. The drilling fluid, also known as mud, is directed onto a vibrating screen on the shale shaker. The shale shaker is equipped with one or more vibrating screens or sieves with different mesh sizes. These screens allow smaller particles and liquid to pass through while retaining larger solids. The shale shaker uses a vibrating motion to convey the drilling fluid through the screens. The vibration helps to separate the solid particles from the liquid mud. As the mud passes over the vibrating screens, the solids are separated based on their size. The larger cuttings are retained on the screens, while the smaller particles and liquid pass through. The separated solids are then collected in a trough or pan beneath the screens. This trough directs the cuttings to a designated area for further processing or disposal. Effective solids control through shale shakers is crucial for maintaining the overall drilling efficiency and reducing wear and tear on downstream equipment like mud pumps and mud motors. Shale shakers are typically part of a larger drilling fluid system that includes other equipment such as desilters, desanders, and centrifuges for further refining the drilling fluid. The choice of shale shaker and its settings depend on various factors, including the type of drilling operation, the characteristics of the drilling fluid, and the specific requirements of the well being drilled. Our GN shale shakers are very user friendly and very dependable. Our patents and our design leads a lot successful operations and through this dedication our clients grow relationship with GN.

Decanter Centrifuge

A decanter centrifuge, also known simply as a decanter, is a specialized type of centrifuge used in various industrial processes for separating solids from liquids. It is particularly effective in applications where the solids and liquids have a significant difference in density. The decanter centrifuge operates on the principle of sedimentation, where centrifugal force is used to accelerate the settling of particles. At GN we have may different sizes of decanter centrifuges. These machines have been operating according to the same basic principle since the 19th Century. Gn produces from 9inch to 30inch bowl. The main function of our centrifuges is dewatering sludge, and mud. Thickening sludge, clarifying different type of liquids, separating 3-phase mixtures, classifying solids in a wet suspension by grain size, and separation of solids according to various densities. The main industries of application of GN centrifuges is Oil and Gas drilling mud solids control, Drilling waste management, oil sludge treatment, HDD trenchless mud cleaning, Bored pile and TBM mud dewatering. Also in waste water treatment, chemical and pharmaceutical separation, mining and food and beverage industry. Our centrifuges are either fixed speed or controlled by VFD. A VFD system can change the bowl speed, differential speed, and pump capacity. It has a touch screen for user-friendly operation and smart control with protection. We also have a fully Hydraulic Drive Centrifuge, which is compact in design and makes it easier for rig set up. The centrifuge works in a way with feed inlet, The mud or slurry is added into the centrifuge through it. As the mixture enters the bowl, it experiences high rotational speeds. The centrifugal force generated by the rotation causes the denser solids to move outward toward the bowl wall, while the lighter liquid phase moves toward the center. The separation process occurs due to the density difference between the solids and the liquid. The centrifugal force acting on the particles causes them to settle at the bowl wall, forming a solid cake. Meanwhile, the clarified liquid, known as the centrate or effluent, collects in the center. To continuously discharge the separated solids, a scroll conveyor or auger inside the bowl rotates at a slightly different speed than the bowl itself. This differential speed helps convey the solids toward the discharge end of the centrifuge. Decanter centrifuges offer continuous and automated separation, making them efficient and suitable for large-scale industrial processes. They are a crucial tool in industries where separation and clarification of liquids and solids are vital for product quality, environmental compliance, or resource recovery.

 

Large Vibrating Screen

GN has developed a large linear vibrating screen for our iron ore clients. It is a large vibrating screen is a mechanical tool used to separate solid particles of different sizes by utilizing the principle of vibration. These screens are commonly used in industries such as mining, metallurgy, coal, construction, and chemical processing. The primary purpose of a large vibrating screen is to separate materials into various sizes for further processing or to remove impurities. Large vibrating screens use a vibration mechanism to induce motion in the screen deck. This mechanism is often an eccentric shaft with counterweights or unbalanced motors. The vibration helps to convey the material along the screen and aids in the separation process. Large vibrating screens may have multiple screen decks stacked on top of each other. This allows for the separation of material into different fractions in a single pass. The screen surface is the area where the material separation takes place. It is typically made of durable materials such as steel or polyurethane. The screen surface may have different opening sizes or patterns to allow for the classification of materials based on size. The drive unit is responsible for generating the vibratory motion. It can be an electric motor or a hydraulic drive system, depending on the design and application. A robust support structure is essential to provide stability and support for the vibrating screen. This structure must be able to withstand the dynamic forces generated during operation. The angle of the screen deck is adjustable and influences the material’s movement on the screen. The angle is typically set to optimize the screening process for specific applications. Material is fed onto the vibrating screen at one end, and the separated fractions are discharged at the other end. The design of the feed and discharge ports can impact the efficiency of the screening process. The screening media is the material used on the screen surface to facilitate the separation process. Common types include woven wire mesh, polyurethane panels, or perforated plates. Large vibrating screens are used in various industries for applications such as scalping, dewatering, classifying, and sizing bulk materials. The specific design and features of a vibrating screen depend on the material characteristics, required throughput, and the operational conditions of the process. GN we have three different types of screens. Large linear vibrating screen, large banana vibrating screen, and large flip-flow vibrating screen. Our large screens assist mining companies with their projects and success.

Tubular centrifuge

A tubular centrifuge is a type of centrifuge that separates liquids from solids or separates liquids of different densities using centrifugal force. It consists of a series of tubular bowls or chambers arranged in a circular or parallel configuration. These tubular bowls rotate at high speeds, generating centrifugal force that causes the separation of components based on their densities. Tubular Centrifuges is artificial slag removal equipment, and the processing capacity is limited, so it is generally used for working conditions with low solid content and relatively small processing capacity. The main separation occurs within the tubular bowls, which are long, narrow cylinders with a series of concentric tubes. The rotating motion of the bowls creates high centrifugal forces that drive the separation of different components. According to the function, high speed tubular centrifuge has two types: clarification type and separation type. The clarification type Tubular Centrifuge is mainly used for separation of liquid and solid, and the separation type Tubular Centrifuge is mainly used for separation of liquid (light phase), liquid (heavy phase), and small amount of solid.

GNGQ — Clarification Type Tubular Centrifuge

The centrifuge rotates at a high speed to reach a suitable working speed (the speed can be adjusted by the electric control panel), and the feeding inlet is continuously fed from the bottom, and a certain feeding pressure (greater than 0.05Mpa) is required. The specific gravity of liquid phase in the feeding inlet is lighter and it gradually spirals upward from bottom to top to continuously discharge from the clear liquid outlet at the upper part of the rotor. The specific gravity of solid phase is relatively heavier, and it settles inside the rotor. After the solid is collected and full in the drum, the machine stops, and the rotor is manually removed for slag cleaning.

GNGF — Separation Type Tubular Centrifuge

The centrifuge rotates at a high speed to reach a suitable working speed (the speed can be adjusted by the electric control panel), and the feeding inlet is continuously fed from the bottom, and a certain feeding pressure (greater than 0.05Mpa) is required. There is difference in specific gravity of the two liquid phases in the feeding inlet, and they are incompatible with each other. The two liquid phases gradually spiral upward from bottom to top until the upper part of the rotor. The liquid phase with lighter specific gravity is discharged from the light liquid outlet, and the liquid phase with heavier specific gravity is discharged from the heavy liquid outlet. The specific gravity of solid phase is the heaviest, and it settles inside the drum. After the solid is collected and full in the drum, the machine stops, and the rotor is manually removed for slag cleaning.

Shale Shaker

A shale shaker is a crucial component in the process of drilling for oil and gas. It is a vibrating screen or sieve that helps separate cuttings (solid particles) from the drilling fluid (mud) during the drilling process. The primary purpose of the shale shaker is to remove large solids, typically larger than 75 microns, from the drilling fluid. Shale shaker is first phase solids control equipment in drilling fluids processing system, also known as key solids control equipment in drilling mud system, shale shaker decides performance of the whole solids control system. GN Solids Control can design double shakers and triplicate shakers on single skid according to clients’ special requirements and also supply relevant connecting manifold, according to current industry situation, GN provide both third generation linear motion shale shaker and fourth generation balanced elliptical shale shaker. Here’s how a shale shaker works, as drilling progresses, the drill bit generates cuttings that mix with the drilling fluid. This mixture is known as drilling mud. The drilling mud, along with the cuttings, flows into the shale shaker. The shale shaker consists of a vibrating screen or mesh that allows the drilling fluid to pass through while retaining the larger cuttings. The shale shaker vibrates rapidly, causing the drilling fluid to pass through the screen. The vibrating motion helps to separate the cuttings from the drilling fluid. The size of the openings in the screen determines the size of the particles that can pass through. The larger cuttings are retained on the screen and are subsequently removed from the drilling fluid. These cuttings are then are typically collected and disposed of. The drilling fluid, now free from larger cuttings, continues its journey in the drilling process. It may go through additional processes or equipment to further clean and condition the fluid before being reused in the drilling operation. Shale shakers play a crucial role in maintaining the integrity of the drilling fluid, ensuring that it remains effective in carrying cuttings to the surface and providing stability to the wellbore. This process is essential for drilling operations in the oil and gas industry, as it helps prevent equipment damage, maintains drilling efficiency, and aids in environmental protection by managing the disposal of cuttings. GNZS linear motion shale shaker absorbed advanced tech at home and abroad ,and integrated GN own design. GN complete series shale shaker can meet customers’ variable demand. Clients feedback proved the advantages of this kind of shale shaker: high G-force, wide screen area, compressed structure, cost-effective, etc.
