GN Double Deck Shale Shaker for Deep well drilling Projects

Deep well drilling represents one of the most demanding frontiers in the oil and gas industry. As operators push deeper into the earth’s crust, they encounter increasingly complex formations, higher circulation rates, and more challenging solids control requirements. In these extreme conditions, the reliability and efficiency of solids control equipment become paramount—and few pieces of equipment are as critical as the shale shaker.


The shale shaker is the first phase of solids control equipment in any drilling fluids processing system and is widely recognized as the key equipment in the drilling mud system


GNZS596K double deck shale shaker is one of the popular shale shaker model among GN solids control equipments, we offer linear motion and dual motion ( linear motion and balanced elliptical motion) for your option, there are two layer decks, the top layer with 2 panels shaker screen, the bottom layer with 4 panels shaker screens, total 6pcs shaker screens, the shaker screen size are same for easier inventory plan, all of the shaker screens are composite material frame shaker screens with stainless steel 316L wire mesh. The screen installation is by ratchet wrench and rapid press for faster fixing and replacement of shaker screens. We also offer 2 options for the bottom shaker screens ( main layer), for normal drilling conditions, flat type shaker screens will be applied which is same with top layer screens. For special requirements on the treating capacity and separation efficiency, pyramid type composite material shaker screens will be applied to meet client’s requirement. The shale shaker is driven by 2ea of 2.2KW vibration motors , the maximum vibration G force is up to 7.5G and it is adjustable. We can produce CNEX, ATEX, IECEX explosion proof vibration motor and starter to meet client’s requirement.

4 Sets GN Mud Cleaning System for Europe HDD company

Recently 4 sets of GN mud cleaning system are ready for delivery to Europe HDD company, including 3 sets of GNMS-200C HDD mud recycling system with treating capacity 200gpm, 1 set of GNMS-1500 HDD mud recycling system with treating capacity 1500gpm.


GNMS-200C HDD mud recycling system is a 200gpm self contained mud recycling system, the cut point is 25 microns, the total volume is 5m3. It is a 2 phase cleaning mud system, the first phase cleaning is double deck shale shaker bottom screen for coarse solids separation, the second phase cleaning is 4pcs of 4 inch desilter cone with mud cleaner. 2 units of centrifugal pumps in same model as desilter feeding pump and a mud mixing pump.


GNMS-1500C HDD mud recycling system is a customized 1500gpm mud recycling system, the cut point is 25 microns. Except for high configuration mud recycling system, GN solids control also produce compact design mud cleaning unit for trenchless HDD project, Bored pile project and micro TBM project, diamond core drilling, water well drilling project. GNMS-200K mud cleaning unit with 200gpm capacity, GNMS-500K with 500gpm capacity, GNMS-1000K with 1000gpm capacity.


Compared with the compact design mud recycling system and the self contained mud recycling system, the table below breaks down the key differences between the two types of systems:

Feature Compact design mud cleaning unit Self contained mud recycling system
Primary function Focus on cleaning Performs mud cleaning, mixing and storage
System complexity Simpler, often a two stage separation process More complex, typically a 4 stage separation process for finer solids separation
Footprint Smaller, skid mounted design for easy transportation Larger, skid mounted or trailer mounted with bigger tanks for greater fluids volume
Application For smaller jobs, supporting smaller drill rig Suited for middle sized to large projects requiring high volume, fine cleaned mud.
