GN Shear Vibrating screen is one kind of circular vibrating screens. It is called circular because of the motion direction, in order to be differentiated from other motions such as linear motions. The circular vibrating screens are widely used for aggregates and sands, mining and waste recycling projects due to their efficiency and reliability.

Here are some features of circular vibrating screens:
1.Unless a linear motion vibrating screen which is using two vibrating screens for generating a linear motion route on screen deck, a circular vibrating screen is designed to use a single vibration source (one vibration motor) to drive and achieve circular vibration of the screen deck assembly.
2.Such circular motion screen can provide a large capacity and handle a high throughput rates, meanwhile, achieve an accurate separating or classification.
3.The circular vibrating screen has a comparably simple structure for easy operating, maintenance and repair.
4.A circular vibrating screen can be designed as one deck or double deck for enhancing the treating capacity or even producing more products.

But in practice, there is one challenge that most of circular vibrating screens are facing, the cut point of separating. Normally, the cut points are a bit too large. At this point, GN has a solution with GN Shear vibrating screens, which is designed to have a high frequency and equipped with flexible polyurethane screen meshes with small apertures. Recently, GN Separation has delivered to a client the shear vibrating screen for silica sand classification.
Besides the shear vibrating screen, GN also manufactures middle sized linear motion vibrating screens for different applications like the mineral processing, aggregates, coal mining, iron ore mining and etc. And for the high frequency vibrating screens, GN has linear vibrating ones with single deck and stack sizers available.

GN Separation is a leading brand for providing equipment and solutions for both separating and conveying. And among the various types of pumps, the vacuum pump is always the most popular one among clients, because of several reasons, for example, the large power and the wide applications.
This time, for the newest vacuum pump project, GN offered a pump for a client in Middle East, and the application is for garnet powder transportation. Garnet is a quite welcome kind of stone in Middle East countries.

About GN Vacuum Pump:
1.The vacuum pump is also called a solids pump because of its feature for tranferring the material with high solid content, even all solids. There are only two limits for the material, one is the liquidity and the other is the size limit.

2.A vacuum pump can be regarded as a pneumatic pump because it doesn’t need any electricity for working. During working, it need an air compressor as an air source to produce the negative and positive force. In this way, the pump can suck in the material from quite a distance and push it to a even further away place. Also because of the air driven without electricity,

3.Vacuum pumps are suitable for different applications for both solids and liquid, and even the material of some viscosity. Of course, the more sticky the material is, the smaller capacity it will achieve. Citing about the vacuum pumps’ applications, they can be used for oily sludge, animal waste, mining ores, sand and small stones, and etc.

4.GN has several models of vacuum pumps for meeting different capacities, like the 10cbm per hour, 20 cbm per hour and the largest 40 cbm per hour. Among those, the 2 smaller models are movable with wheels.

Each year, GN manufactures and sells 200+ sets of decanter centrifuges, and more than half of this number would be sold to the oil and gas industry. They are always used for oil and gas driling solids control, drilling waste management, drilling mud dewatering and oily sludge treatment.

Centrifuges are used in above mentioned facilities because of the decanter centrifuges’ characters. As the decanter centrifuges’ working principle, by means of the high speed rotating of the centrifuge bowl and the different rotating speed between the bowl and the centrifuge propeller, the solids phase and liquid phase would be separated to each port. A centrifuge’s ideal cutting point is between 2 to 5 microns.

Also as a solution provider for separating works, GN Solids Control can also design a turnkey solution for clients. Here is one of a recent project GN provided to a client in South America. The client purchased 2 sets of following:

1.Big bowl decanter centrifuge GNLW654. GNLW654 is one of the large centrifuges of GN Centrifuge family, but not the largest model. GN offers centrifuges from 9 inch diameter bowl to 30 inch diameter bowl. And the length diameter ratio can be made as 3 or 4. For electric control panels, GN use VFD control panels with smart control.
Dewatering unit with a 6000L capacity for flocculation.

2.A dewatering unit for chemical dosing, As mentioned, the ideal cutting point of a decanter centrifuge is from 2 to 5 microns. When there are particles too large for the centrifuges, there should be some other equipment for pre-treatment before the centrifuge, for example, a shaker. But when the particles are too small, we use a dewatering unit to add polymerinto the material to flocculate the particles into larger ones in order to be chosen out by a centrifuge.

3. A telescopic stand for each centrifuge.

4. Screw pump for decanter centrifuge feeding.
