Shale Shaker and Mud Cleaner with Spill proof cover to China Drilling Company

Solids control equipment is main business of GN. Since 2014 the year GN funded. GN had developed his own whole series solids control equipment, include shale shaker, mud cleaner ,Decanter centrifuge ,vertical cutting dryer, and also the matched centrifuge pump and screw pump. GN is one of less manufacture that can manufacture the whole set solids control system. As long as we development more and more customer, we are also keep upgrading our equipment and make it can reach most client’s requirement, and provide more stable ,more efficiency equipment to customer.

Last week we delivered one shale shaker and one mud cleaner to China drilling company. Compare with normal shale shaker, we added spill proof cover on shaker and mud cleaner. It is not a complex design, but it is very useful for user to keep the clean of jobsite. This cover was manufactured by stainless steel, and has certain corrosion resistance, so it not only can be used for drilling mud treat ,it also can be used to process some special material such as mining sludge. This cove can be uninstalled when client do not use it.

When design this shale shaker, the engineer considered lots factor to convent user when operate this machine. Such as the wedge design to fix shaker screen. The user only need the Ratchet wrench to fasten and wedge to press shaker screen and fix it, it is very quick and high efficiency to replace shaker screen. And also the adjustable shaker deck, user only need to screw the jack-up device in one side of shale shaker, and then can adjust the deck angle from -1~+5°. GNZS-594 model can install the same size shaker screen of mongoose, so the user only can get the shaker screen from GN, but also can find the replacement screen in every where of global.
After the continuous upgrading, the shaker seems no part to improve. If you have demanded on our equipment, welcome to contact us.

GN Mining Vibrating Screen

As we all know GN solids control has focused on solids control equipment of oil gas industry for more than 15 years. In the past 15 years, we built long terms relationship with many top energy company, and get the reputation from the market, meanwhile we accumulated lots manufacture experience of equipment and also separating technology. In 2019,we built our other GN brand and it is GN separation, GN separation concerned on the separation equipment of different application, mining vibrating screen if one main product of it. Till now, we have completed our whole series equipment line of vibrating screen. Today I am going to share our mining slurry dewatering shaker.

Different with oil gas industry, mining vibrating screen required much higher treating capacity and long lifetime. On solids control equipment, we used the steel wire mesh as the main filter material to separate the solids off liquid, and its lifetime is about 400 hours. However, 400 hours is too short for mining industry. Polyurethane material screen is a good selection for mining sludge. It is more anti-vibration and longer lifetime. As usually, one PU screen can user about half year. Except the material , the whole screen was spliced together by several small screen modular. When partial of screen was damaged, we just need to replace the damaged part, it is good to save money of screen.

BIG treating capacity is the most feature of mining vibration screen. The biggest model of GN mining vibrating screen can separate out 40m3/hour of dry solids. And this vibrating screen is 7×24 hours continuous work without stop. From the photos we can see, the vibrating deck wall used large rivet to instead of welding technology. This design of rivet can stress relief , and raise the wall strength.

Except dewatering screen, we also can provide classification vibrating screen to classify different size mining particle, if your project have demanded on our equipment, welcome to contact us.

The type of liquid phase in drilling mud

Today we will share some knowledge of liquid phase of drilling mud. The liquid phase of drilling fluid has many kinds of fluids that can be used as the liquid phase of drilling fluid. For example, fresh water, saline water, salty water, saturated saline water, diesel oil, crude oil and a variety of mineral oil and modified vegetable oil. Which liquid phase is selected mainly depends on the inhibition required by the drilled formation. The liquid phase has strong inhibition ability, which can prevent the reduction of soil fluid and the expansion of active solids, thus limiting the formation slurry making ability. Fresh water is the best medium for sticking to the hydration (expansion), and also the liquid with the worst inhibition



Oil is the best non-ionic inhibiting fluid. At present, water in oil-based drilling fluid exists in an emulsified state and is bound by oil. Therefore, this water in oil drilling fluid has the advantages of less damage to low pressure and low permeability reservoirs, preventing shale hydration expansion, preventing collapse, lubricity, maintaining the original state of active chips, weakening or completely stopping hydration, etc.

Salt water can also be used to inhibit the hydration of solids in the liquid phase. The inhibition ability depends on the concentration and type of salt dissociation. The higher the salt concentration is, the stronger the inhibition ability is, and the saturated salt water has the strongest inhibition ability.
GN Solids control focused on solids control equipment for more than 15 years. We can manufacture the whole series solids control equipment. Such as shale shaker ,mud cleaner, mud jet mixer and decanter centrifuge. We provided solids control equipment to more than 76 countries and served more than 100000 project. GN get the good reputation from customer , and built lone term relationship with customer with lots top oil gas company of the world. If your project have demanded on these solids control equipment, welcome to contact us.

The principle of mud agitator

The well drilling fluid is used to balance the formation pressure, transfer power, remove cuttings and carry them to the surface, and stabilize the wellbore by physical and chemical means.
In the over or under compacted formation, or the easily dispersed and expansive formation, the directional well fluid becomes more challenging, and special measures are required to ensure that the well fluid performance is sufficient to deal with these situations. The well fluid prepared with viscosity increasing agent, thinner, weighting material and special additive can meet the special needs of the site. At the same time, in order to reuse the well fluid, the well fluid cannot be over diluted, and the cuttings must be removed from the well fluid. This chapter mainly describes the importance of mixing to the well fluid circulation system. This chapter also details the adverse effects of incorrect mixing, anti floating and mixing on the well fluid. In addition to mixing, mixing, shearing, ingredients and chemical additives are also important for well fluids. When the size and installation can make additives and chemicals with maximum speed and minimum problems.

The function of the surface well fluid system is to allow the well fluid to be maintained and treated before being tied into the well. This can be achieved by effectively using solid control equipment to remove unwanted solids, and at the same time, recycle well fluid as much as possible. After the solid phase is removed, the next step is to quickly and completely mix the chemical additives and well fluid materials. Full release and mixing is very necessary for solid removal and maintenance. Most of the wrong well fluids must be mixed with equipment to avoid solids in the floating tank, so as to keep the well fluid composition uniform. There are two kinds of equipment that can achieve this goal: mechanical release mixer and well fluid gun
GN Solids Control was one manufacture that can produce the whole solids control equipment include mud agitator and mud gun, if you have need on these equipment, welcome to contact us.
