Before starting the decanter centrifuge, check in advance: whether the overload protection device is in normal working condition; whether the fastening bolts everywhere are loose; whether the drum can rotate normally; whether the moving parts and static parts are rubbed. Continue reading →

GN Separation has recently completed the assembly of two GNLW224 decanter centrifuges, known for their compact design that merges innovation with durability. These versatile machines are ideal for various industries, including environmental protection, salt chemicals, and oil & gas exploration.

The GNLW224 decanter centrifuge can exemplify GN’s dedication to technological excellence, featuring a bowl diameter of 220mm and a length-to-diameter ratio of 4.2. This design optimizes space while maintaining top-tier performance. With a rotational speed of up to 5000 RPM, the centrifuge delivers high-speed separation, generating powerful centrifugal forces to ensure superior separation efficiency. The bowl, made from duplex stainless steel 2205 through a centrifugal casting process, offers enhanced balance and resilience, capable of withstanding harsh operating conditions while reducing vibrations and extending the machine’s lifespan.

Supporting Diverse Industries

1. Environmental Protection: Sludge Dewatering

In the environmental sector, GN’s decanter centrifuge is widely used for sludge dewatering. Its ability to efficiently separate water from sewage sludge significantly reduces waste volume, lowering transportation costs and enabling more eco-friendly sludge management. The improved sludge dryness also supports energy recovery through anaerobic digestion, contributing to the circular economy in wastewater treatment facilities.

2. Salt Chemicals: Crystal Salt Dewatering

In the salt chemicals industry, the decanter centrifuge is crucial for crystal salt dewatering. Salt producers depend on precise separation techniques to achieve high-purity salt crystals, and this machine excels in delivering low moisture content in the final product, enhancing both quality and profitability. Its durable design efficiently handles abrasive salt particles, ensuring consistent performance over long periods.

3. Oil & Gas: Drilling Mud Recycling

The oil and gas industry generates significant amounts of contaminated drilling mud containing valuable drill cuttings and fluids. The decanter centrifuge offers an effective solution for separating these materials, reducing waste disposal costs and facilitating mud recycling. By separating solid particles from fluids quickly and thoroughly, it minimizes the need for fresh mud and improves overall drilling efficiency. The centrifuge’s high-speed operation ensures continuous processing, supporting uninterrupted drilling activities.
