GN CBM Drilling Mud System

GN Solid Control has recently designed and delivered a modular hydrovac slurry dewatering system for an overseas client, providing an

efficient and reliable solution for construction slurry, drilling mud, and industrial wastewater treatment. This advanced system integrates

five core modules—coarse screening, fine screening, desanding & desilting, centrifugation, and chemical dosing—ensuring optimal

solid-liquid separation and environmental compliance.

Key System Modules

1. Coarse Screening Module – GNLMP-1536

The GN GNLMP-1536 mining coarse screen utilizes advanced screening technology to efficiently remove large particles from construction slurry.

With high screening efficiency and large processing capacity, this module serves as the first step in slurry pretreatment, preparing the material

for further fine separation.

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.

5. 20ft Chemical Dosing & Flocculation Module

The GN automatic chemical preparation and dosing unit provides fully automated polymer mixing, storage, and injection, ensuring precise

flocculant concentration for enhanced dewatering. Compatible with decanters, screw presses, and filter presses, this system is widely used

in wastewater treatment for petroleum, chemical, paper, power, coal, pharmaceutical, and food industries.

System Advantages

✔ Modular Design – Easy transportation, installation, and quick on-site deployment

✔ High Efficiency – Multi-stage separation from coarse screening to fine centrifugation

✔ Intelligent Control – Automated chemical dosing and centrifuge adjustment reduce manual operation

✔ Eco-Friendly – Reduces slurry waste volume and meets environmental regulations
