GN Made Great Success in the 20th International Trenchless Show

GN Solids Control just came back from the 20th International Trenchless Technology Conference 2016 with great success. The 20th conference was held in Beijing Conference Center, during this show there had been a large quantity of professional visitors come to this show and share experiences as well as exchange opinions.
During this show, GN Solids Control exhibited one set of 500GPM mud treating system and one set small centrifuge. GN Solids Control has designed and manufactured whole mud treating and recycling mud systems for global no dig industries for many years. Until now, GN Solids Control mud systems have been successfully used in over 60 countries. GN manufactures economy mud systems and high configuration systems, most of these systems are used by global large customer such as Vermeer, Major Drilling, Schrumm and CNPC etc.

With these years’ fast development, GN Solids Control has provided two choices for our customers: one is standard mud system, like to GNMS-500D exhibited in this show; the other mud system is all customized based on customers’ detailed demands.
For those standard mud systems, GN Solids Control is able to manufacture them in a really short period before leave factory. And they can be put into use immediately. GNMS-500D is designed and manufactured in a pretty compact structure: one desander is mounted on the top of settling tank where a centrifugal pump is fixed. Drill slurry is feed into the bottom shaker first, where the coarse solids will be separated out. Then centrifugal pump will be used to feed into the desander cyclone for further separation. There is also a second deck shaker with finer screens, slurry discharged from the cyclones with the treated by this deck again. A clean drilling fluid is stocked in the bottom declined tank and can be reused for drilling.
Sometimes, a mini centrifuge will be used for further separation. GN 9 inch rotating bowl decanter centrifuge can be used in this situation. While sometimes for large volume treating, you might need a 30inch bowl decanter centrifuge.

GN 500GPM Mud Treating System for HDD Construction

GN Solids Control provides standard and customized mud systems for No Dig Drilling areas. With these years’ fast development, GN Solids Control has provided hundreds of compact mud systems for HDD area.
GN Solids Control has 200GPM, 350GPM, 500 GPM and 1000PM mud system can be chose. Based on customer’s special demands, GN Solids Control also provides customized HDD mud recycling systems.

GN HDD mud treating systems are divided into two groups:
1. Economy Mud Recycling System: mud treating systems only have shakers and desander or desilters;
2. High Configuration Mud System: this type mud treating systems have storage tank and mixing tanks.
Today, we would like to give you an introduction based on the working process of GNMS-500GL high configuration mud system.
The main equipments in GNMS-500GL system including: shaker, mud cleaner (with desander and desilter cyclones) and mixing tank.
A submersible pump is usually used to pump the mud to the GN shaker, which is GNZS703E-DE with 3 panels’ shaker screens assembled on it. Drilling mud separated by the shaker will fall off to the bottom tank, which will be feed by one centrifugal pump to the 10inch desander cyclones for the next phase separation. Then the 4 inch desilter cyclones will help to remove much finer solids most of them are above 25mircons.

From the working function, the first shaker and mud cleaner tank is also called shaker tank, while for the rest part it is called mixing and storage tank. Clean drilling mud are stocking in the mixing tank, by adding some chemicals GN Solids Control mud systems provides effective drilling mud to the drilling rig. These drilling mud can be reused again.
All the above equipments can be put in one standard container, which will help to save shipping freight. As shaker screens are wearable parts when using in the shaker, GN Solids Control also manufactures the most cost effective shaker screens.
