2. Double-Layer Fine Screening Module Shale Shaker – GNZS596K

The GNZS596K double-deck shale shaker is widely used in piling, tunneling, oil & gas drilling, and industrial separation processes,offering a

maximum processing capacity of 140 m³/h (616 GPM). Its dual-layer screening design enhances separation accuracy,ensuring finer solids

removal.

3. Desander & Desilter Module – GNZJ594J-8N

The GN mud cleaner combines a desander cyclone, desilter cyclone, and bottom shaker into a compact yet powerful unit. It serves as an ideal

secondary and tertiary solids control solution for drilling fluids, effectively removing fine particles and improving fluid cleanliness.

4. Decanter Centrifuge Module – GNLW553D-VFD

The GNLW553D-VFD is a 22-inch large-bowl decanter centrifuge featuring a full variable frequency drive (VFD) system (ABB/Siemens inverter).

Its intelligent control system automatically adjusts feed rate, bowl speed, and differential speed for optimal dewatering performance. With a

3.3:1 or 4.2:1 length-to-diameter ratio, this centrifuge is ideal for high-capacity slurry treatment across various applications.
