Desilter

Desilter is the third stage solids control and fourth stage drilling mud cleaning equipment in the drilling fluids recycling system. GN Desilter commonly adapts 4” cyclone which could separate the solid phase particles with size of 15-25 microns. GN Desilter is designed 2 options of with and without underflow screen for customers’ requirement. 

The desilter with underflow shaker is also called Mini cleaner which is applicable for both weighted and unweighted drilling mud, while traditional desander no underflow vibrating screen only for unweighted drilling fluids. And comparing with large size desander and desilter assembly, the Mini Desander is cost-effective. For compact mud system used in HDD, CBM, water well drilling and Mining project, Mini desilter cleaner is an Ideal choice.

GN Desilter Features:

• The entire shaker deck undergoes heat treatment to relieve welding stress, enabling it to withstand high G force.
• The shaker screen is installed with a mechanical ratchet wrench gear for quick tightening, facilitating easy disassembly and ensuring long-lasting durability.
• The wedge blocks for tightening the screen mesh are made of nylon, providing high temperature resistance, corrosion resistance, and wear resistance.
• Vibration motor: Italian OLI brand.
• Polyurethane material is used for sealing between the shale shaker and screen, ensuring a long service life and easy replacement.
• The supporting rubber strips for the bottom frame of the vibration screen are made of stainless steel, offering strong corrosion resistance and a long service life.
• The electrical control box is made of aluminum alloy/stainless steel explosion-proof material, ensuring good sealing and strong corrosion resistance.
• The pre-tensioned shaker screen allows for convenient and quick disassembly and replacement.

Mud Desilter for Drilling Mud Separation System:

Desilter is placed after desander but before Decanter Centrifuge. Desilter is also one type equipment to remove the solid particle in drilling through centrifugal force. Desander could remove the much fine solids than desander. During HDD and CBM mud system, the drilling mud after treated by desilter is clean enough for reuse. While in oil & gas drilling, there the mud still needs to be treated by a Decanter Centrifuge.
