Superior Material Quality

All wet-touching parts of the GNLW364 Decanter Centrifuge are constructed from duplex stainless steel 2205. This material choice ensures excellent corrosion resistance and durability, making it ideal for the harsh conditions often encountered in industrial applications.

Understanding the Decanter Centrifuge

The full name of the decanter centrifuge is the horizontal screw decanter centrifuge. This equipment is widely used across various industries for solid-liquid separation. GN Separation, a leading manufacturer of decanter centrifuges, offers different types tailored to the characteristics of specific materials:

  1. T Series Dewatering Type (8.5° Beach Angle): Designed for materials with large particle size, high density difference between solid and liquid, low viscosity, high concentration, and high treatment capacity. It excels in dewatering applications where sludge or wastewater containing fine particles often require flocculants to aggregate these particles into larger ones for effective dewatering.

  2. Y Series Separation Type (15° Beach Angle): Combines the benefits of the T Series dewatering centrifuge and the C Series clarifying centrifuge. It ensures both the clarity of the liquid phase and the dryness of the solid phase. This type is particularly suitable for separating fine, soft materials with small particles, small density differences between solid and liquid, large viscosity, and small concentration.

  3. C Series Clarifying Type (20° Beach Angle): Ideal for materials that are difficult to separate, have small particles, small solid-liquid density differences, moderate viscosity, and require high clarity of the clear liquid.

  4. SX Series 3-Phase Type: Designed for solid-liquid-liquid 3-phase separation, where the solid phase is heavier than the liquid phase, and the two liquid phases are immiscible with different densities.
