The GN Decanter centrifuge is a horizontal centrifuge extensively utilized for solid-liquid separation across various industries such as wastewater treatment, food and beverage production, oil and gas processing, and pharmaceuticals, based on the distinct properties of different materials.
This centrifuge functions on sedimentation and differential centrifugal force principles. It comprises a rotating bowl, a screw conveyor, and a collection system. The mixture to be separated is introduced into the rotating bowl, where centrifugal force pushes the heavier solid particles to the bowl's outer edge, forming a solid layer, while the lighter liquid creates an inner layer. The screw conveyor then moves the solids toward the conical end for discharge, and the clarified liquid is collected separately.
GN Decanter centrifuges come in several series:
T Series (Dewatering): Beach Angle 8.5°. Ideal for separating materials with large particle sizes, high-density differences, low viscosity, and high concentration, like sludge or wastewater, often requiring flocculants.
C Series (Clarifying): Beach Angle 20°. Suited for separating materials with small particles, minor solid-liquid density differences, moderate viscosity, and concentration, demanding high clarity.
Y Series (Separation): Beach Angle 15°. Combines dewatering and clarifying features, perfect for fine, soft materials with small particle sizes, minimal density differences, high viscosity, and low concentration.
SX Series (3-Phase): Beach Angle varies by material. Used for separating solid-liquid-liquid mixtures where the solid is heavier than the liquid phases, which are immiscible and have different densities.
GN Decanter centrifuges are exported to over 60 countries and are highly praised by users. As a leading manufacturer, GN focuses on quality and user benefits. High-quality stainless steel and hard alloy protections ensure durability, while advanced CNC machines maintain precision. High-speed dynamic balancing enhances operational stability.
GN Decanter centrifuge is a type horizontal centrifuge, which is widely used equipment for solid-liquid separation in different field of industries according to the characteristics of different materials such as wastewater treatment, food and beverage, oil and gas, and pharmaceuticals.
The decanter centrifuge operates on the principle of sedimentation and differential centrifugal force. It consists of a rotating bowl, a screw conveyor, and a collection system. The mixture to be separated is fed into the rotating bowl, where centrifugal force causes the heavier solid particles to settle at the bowl's periphery, while the lighter liquid phase forms an inner layer. The screw conveyor then transports the solids towards the conical end, where they are discharged. The clarified liquid is collected and extracted separately.
GN decanter centrifuge is divided into T Series (dewatering type), Y Series (separation type), and C series (clarifying type) , SX Series (3-phase type)
T Series: Dewatering Decanter centrifuge, Beach Angle 8.5°
Usually used for removing liquid phase from solid phase materials. It is designed fo materials that are easy to separate: with large particle size, high density difference of solid and liquid, low viscosity, high concentration, high treatment capacity and higher dryness than clarity. For instance, sludge or wastewater containing fine particles usually need to be added with flocculants to gather the fine particles condensed into large ones, and then dewatered with T series decanter centrifuge.
C Series: Clarifying Decanter centrifuge, Beach Angle 20°
Generally used for materials that are difficult to separate: with small particles, small solid-liquid density differences, moderate viscosity, moderate concentration, and require high clarity of clear liquid.
Y Series: Separation Decanter centrifuge, Beach Angle 15°
Combining the advantages of T series dewatering decanter centrifuge and C series clarifying decanter centrifuge, it is designed not only for the clarity of liquid phase after separation, but also the dryness of solid phase. Y Series separation decanter centrifuge is especially suitable for fine soft material separation. It is usually used in soft materials which are difficult to separate. It suits for material of small particles, small density difference in solid-liquid, large viscosity and small concentration.
SX Series: 3-Phase Decanter centrifuge, Beach Angle according to material condition
3-Phase decanter centrifuge is mainly used for the separation of solid-liquid-liquid. It is required that the solid phase is heavier than the liquid phase, the two liquid phases are Immiscible with different densities.
GN decanter centrifuges are widely used in the industry, and the products are exported to more than 60 countries and regions in the world, and have won high appraisal from customers. As a leading manufacturer, GN always pays high attention to the quality and also considers the long-term benefits of users.
In the selection of raw materials, high-quality centrifugal casting and forging stainless steel materials are used. For wearing parts, hard alloy protection is used. GN high-end CNC lathes, CNC centers, and CNC gantry milling machines can ensure the machining accuracy of centrifuge parts.
In terms of the dynamic balance of decanter centrifuge, in addition to low and medium speed dynamic balance, GN also applies a high speed dynamic balance process, which can dynamically balance the centrifuge screw and bowl at the actual working speed. In terms of market applications.
