Hydro cyclone separator: mud cleaner, desander and desilter

There are different type and sizes of Hydro cyclone separator used for oil and gas drilling field. It is also widely used for soil purifications. It is the 2nd and 3rd stage separation system in mud cleaning systems.

Per the different sizes of hydro cyclone, we call it desander or desiter. Desander separator is with big hydro cyclone to remove bigger size solids. Normally, when the cone size if bigger than 8 inch, we call it desander separator. Like 20 inch, 16inch big size, they are normally used for micron tunneling and piping projects for coarse solids. While 10 inch is popular for oil and gas drilling mud system, HDD, water well drilling mud recovery system and desanding plants.


For cones smaller than 8 inch, we call it desilter, like 6 inch, 4 inch and 2 inch. 4 inch is the most popular for oil and gas drilling, while 2 inch is normally used for soil purification or drilling waste management to remove small size particles.

Desander cone and desilter cone can be used separately or combined together in a system. As hydro cyclone is not D100 separation device, there normally will be a under flow shale shaker for further separation.

GN Solids America LLC’s large treating capacity decanter centrifuge

GN Solids America LLC manufactures the decanter centrifuge in various sizes to meet the demand of the liquid-solids separation.  For demand on solids-water separation, the projects tend to choose high RPM decanter centrifuge but the treating capacity is small.  Most drilling projects are tend to achieve both acceptable solids-water separation and treating capacity at the same time and tend to choosing mid-size bowl such as 14 inches and 18 inches.  Of course some project demand on more treating capacity then solids-water separation and it will choose bowl size of 22 inches to meet the project need.  GN Solids America’s GNLW553C-VFD is to meet the demand of treating capacity while perform reasonable solids-water separation.

waste centriufge

VFD stands for variable frequency drive. It means GNLW553C-VFD is come with control panel that can adjust RPM of bowl spinning to met various water condition that contain various types of solids that needs to be separate from the water.  The purpose can be performs solids recovery or reuse of water.      It has been applied for various industries, for example drilling waste management system, dredging slurry separation system, dewatering unit for TBM waste water treatment, industry waste water treatment, mining tails treatment, oil sludge waste treatment, even solids control system. It is the biggest model we have right now, drives by VFD control panel, and the bowl size is 22inch bowl diameter by 71 inch bowl length.

The point to have big bowl design decanter centrifuge is to have more treating capacity on the solids-water separation project and it is difficult to build big bowl decanter centrifuge that also can have enough RPM spinning speed to do separation due to the weight and the balance of the bowl while spinning in high RPM.  GNLW553C-VFD can be use as stand-alone unit and also can linked with other solids control machinery to become a part of mud cleaning system.

GN Vertical Cuttings Dryer working in West Africa

GN Solids Control is the leading brand of solids control and drilling waste management based in Beijing, China and Houston, US. In order to deep the market, GN always invest in new product research, production management, quality control, customer experience and after sales service. With many years hard work, GN people open the market and export large quantity of solids control equipment to overseas market.  I am in Charge of Africa market, and I will write to focus on North Africa and West Africa market. South Africa only have diamond, and very few oil drilling company active there.


The North Africa countries active in oil drilling including Egypt, Algeria. Libya have lots of oil reserve, but the government is not stable and situation is suitable for stable business development. This is really great pity for our company. Tunis is only big in area, really not active in oil drilling activity. I don’t know why. Let’s talk about Egypt and Algeria market. We just signed registration with Egypt largest drilling company, and if the product is qualified, we will support them in next years. We hope so. In Algeria, it is really hard market even the oil drilling activity is good there. Every purchase process need tender.


The West Africa top oil country is Nigeria. We have export over 2million dollar equipment to Nigeria in the past 2 years. And one drilling company have bought 3 sets vertical cuttings dryer for drilling waste management and 10 sets of decanter centrifuge for solids control. All the equipment have been working for over 2 years and the client is satisfied with the working performance. We hope the world crude oil price will go up to 80 dollars, and our business will also come up soon. Other West Africa countries, we have a few clients.


So, as a oil equipment supplier, we rely on Egypt, Algeria and Nigeria in a large degree. Hope the business will restore very soon. Best regards.

GN solids control American changing diamond designed screens

Drilling fluid shale shaker screen is an important component of the solid particles in liquid filtration, is all sorts of disposable parts often need to change in the well drilling project.

Due to the drilling fluid is corrosive, and need to filter solid particles, using over time can cause wear and tear, normally shale shaker screen materials are made of stainless steel and heat treatment technology of steel wire. Auxiliary support structure made of steel plate, galvanized sheet and other materials.
With the continuous development of science and technology, in order to improve the filtering effect of screen mesh, diamond shape screen mesh was developed. It is from the flat screen to improve and upgrade, began in the mid – 1990 – s.
Diamond-shaped mesh screen mesh for common crochet net and orifice plate bonding has absolute advantage, but it will not change based on the vibrating screen structure size, and frequency and the vibration force of the vibrator will not change.

The advantage of diamond vibrating screen mesh is broken the limitation of the traditional flat screen, due to the unique wavy screen, not only to improve its service life by, and increased the filter plate filter area, increase the filter area of filter plate.
When drilling fluid flows to the surface of a mesh screen, solid phase flow ripple trough, vertical plane can provide more drilling fluid filter area, so compared to flat screen, wave screen through capacity and throughput than orifice plate bonding screen and other flat screen large 30% ~ 40%, and the diamond mesh also added the retention period of drilling fluid on the screen, has better screening effect.
Designed.the GN solids control of main products in addition to the drilling fluid shale shaker screen, can also provide solids control system and drilling waste disposal equipment, such as decanter centrifuge, drilling fluid shale shaker, mud cleaner, mud tank, vacuum degasser, shear pumps, mud agitator etc.
