GN Solids Control is China leading company to manufacture the solids controls equipment and drilling waste management equipment. Shale shaker as the first phase separation equipment at mud circulation system, play an important role in the system. Our company founded 7 years before and we start the shale shaker design and production from then.  Until now, GN shale shaker have been exported to over 60 countries and areas for oil drilling application.

For now, GN Solids Control have different type shale shakers for option,  2 panel shaker, 3 panel shaker and 4 panel shakers. The client can choose the proper model to fit their unique project

.shale shaker

2 panel shaker GNZS752E is mostly used in non oil drilling industry. Most of client buy the mini shaker for diamond drilling or waste water treatment.

3 panel shaker is mostly used in HDD drilling, waste water drilling and Workover rig mud cleaning system. Some client also use the 3 panel shaker for oil drilling project.

4 panel shaker is most popular in oil drilling project. The shaker with longer deck can have better treating performance, mostly used in 500gpm mud system, 1000gpm mud sytem, 1500gpm mud system.

GN 4 panel shaker is replacement for Swaco Mongoose shaker. We have same type shaker screen which is replacement for Swaco Mongoose composite material shaker screens. Cheaper price carbon steel frame material screen is also available.f

GN 4 panel shaker can also be used for drilling waste management, water based mud drilling cuttings drying process. We call the shaker High G drying shaker or High G dryer in drilling waste management. After treated by GN high G drying shaker, the OOC can be reduced to about 10%, and the valuable Water based mud can be collected for reuse and the dry cuttings can be buries for permanent stock.

For oil based mud cuttings treatment, we recommend Vertical cuttings dryer for better performance, the OOC can be reduced to below 5%. OBM cuttings are more hazardous to environment and need to be taken care of more carefully.

The company who provides the environmental protection service may have this company for dredging in canals or lakes. Many years’ soil sedimentation down to water bottom, leaves falling in the water and then rot, as well as the trash threw into the normal water will make the river mattress higher and higher which leading often the pollution of the water and also the cutoff of the water flow. Therefore , we need take action to take out the sand, silt and trash at the bottom connected with water to make the water clear.
To take the solid things out from the water, we need a good and liquid separation system to do this job. As a foremost manufacturer of solids control equipment, GN solids control luckily jointed a project to really make the lake water clean really residence district. There is a dredging boat that can take the strong mixed with water from bottom level of the lake, the grubby slurry was sucked away and delivered on to the property with smelly smell.

Hull cleaning system

Hull cleaning system

The actual slurry is fed using a steel wire box just where large size solid stuff will likely be blocked and collected. Then your liquid will be pumped to be able to GN’s solids control system. In this system, GN created 3 stages for solids control including shale shaker, de-sander and de-silter. The de-sander and de-silter have underflow shaker that could stumble through discharges from cyclone considerably dryer. After treated with the de-silter cyclones, the sturdy stuff with size bigger than 15-20 microns will be eliminated. And the rest solid from the slurry is difficult to eliminate by using mechanical machinery.
Flocculation is a good method to gather often the ultra fine solids within the slurry. Add the flocculation agent into the slurry depending on certain ratio and then entirely mix with agitators. The flocculated slurry will need several times with regard to sedimentation and then will be streamed to belt filter click for final dewatering method. The solids will be dismissed with a thin cake design, and the water could be wiped away directly back to later or maybe river.
The advantage of the filtration system press is to make the solids much dryer, and negative aspect is high cost and modest treating capacity. Some other service provider will use decanter centrifuge to try and do the final dewatering job with consideration of its much larger treating capacity.

Every year, GN Solids Control provides many sets of solids control equipments or waste management systems for customers. All of these equipments are thoroughly discussed with customers before put into manufacturing. GN experienced workers are sparing no effort to manufacture excellent equipments with first class quality, which is also guaranteed by GN QC engineers. These whole equipments are assembled and tested before sent to customer’s worksite to make sure everything going well and save customers time, so when they’re arrived, these equipments can be put into use in a short period. Sometimes, there’re some equipments that will not be disassembled when transporting. For those customers need technical help from GN, GN can sent our experienced engineers to their worksite. Based on different work site’s environment, GN engineers will take all the solids control equipments into consideration which also involves in the layout of course. GN-Mud-System

Recently, GN Solids Control Co. has provided one whole set of mud system which is not the common layout. Since the room is limited, to put two shale shakers side by side is not possible. So after careful consideration, GN recommends to put the mud cleaner between two sets of shale shakers. As we all know, mud cleaner can separate much finer solids than shale shaker, so even we arranged to put the mud cleaner in the middle, we try to rearrange the two shale shakers pipelines. Pipelines from the separated shale shakers are connected to the mud cleaner directly, and the inlet pipelines to shale shakers are also separated. In order to keep the safety and protect the shale shaker, all the shaker deck are fixed with bolts before transportation. So when the shake arrives at customers’ worksite, these fixed bolts need to be disassembled first. GN also pays to some other details to keep all the equipments to use for a long life, such as use rubber coat to protect the shaker spring, use rubber slips to protect the shaker screens. GN equipments are devoting to the best!

Nowadays, the most popularly used oilfield shale shaker are BEM(Balanced Elliptical Motion) and Linear Motion. In China, GN Solids Control is the first one who got the API Certificate for producing shale shaker and other drilling fluids recycling equipments for oilfield application.

 Linear Motion Shale Shaker

Linear Motion Shale Shaker

When need shale shaker BEM or Linear Motion

Usually, shale shaker is used as the first stage drilling fluids recycling equipments in the Mud System, and the drilling fluids with cuttings flow into the shaker distribution box through rig elevated manifold.

  • Linear Motion – for fast conveyance and heavy loading

Linear motion shaker is especially effective while drilling top hole sectiong where heavy, high volume solids are usually encountered. In these intervals, shakers need to generate high G forces to effectively move dense solids across the screens.

  • BEM – for maximum retention time and drier cuttings

The BEM type shale shaker has gentler reduced G force, and the special vibration mode make the solids stay on the screen for longer time. This results in drier solids, improved drilling-fuid recovery, longer screen life and reduced operation costs.

BEM Shale Shaker Manufacturer

MI Swaco, a Schlumberger company, could offer the Mongoose PT daul motion shale shaker which could be adjust the vibration mode from linear motion to BEM “on the fly” by fliping the switch without suspending or shutting down the operation.
GN Solids Control, only foucs on International market and high level domestic market, could offer both the Linear motion and BEM shale shaker used in not only Oilfield, but also the HDD & CBM.  The simple structure design and top quality make GN get more and more praise from our customer.
Mongoose daul motion shale shaker by using an extra 0.6hp vibration motor to allow the shaker perform on an unparalleled level, GN’s BEM shaker is using 2 units motor with different power.

Comparing with BEM shaker, Linear motion is more acceptable due to the mature technical and large quantity oilfield application experiencies. GN Solids Control would be your reliable supplier for solids control equipments once you have any request aroused.
