A batch of GN Mini Decanter Centrifuges to be delivered to European Customer

Decanter centrifuges are widely used in various drilling industries for the separation of solids and liquid, including the oil and gas drilling, geothermal drilling, diamond drilling and pipe jacking. Based on different requested drilling capacities, there are different sizes of centrifuges for option. This time, for this European customer, GN provided a decanter centrifuge of 9 inch diameter bowl, which is the smallest model among GN Centrifuges.

2023.02.24 Mini decanter centrifuge

1. GNLW223 Decanter centrifuge. It is also called a baby centrifuge among all GN centrifuge models. The length diameter ratio is 3, which is a typical value for drilling mud separation works. The largest RPM it can reach is 4500RPM, and it can efficiently remove all the particles from 2 to 5 microns.

2. Applications of GNLW223 decanter centrifuge. GNLW 223 decanter centrifuge is small but popular. It is widely used among GN clients in diamond drilling projects, geothermal well’s drilling, HDD projects and animal waste treatment. It is a compact model especially in North America and Europe.

3. Special design for this batch of GNLW223 decanter centrifuges. When the centrifuge is put into use, it should be put on a certain height in order to discharge the liquid and solids. That’s why there is always a skid, sometimes telescopic, under the decanter centrifuge. For this batch of decanter centrifuges, GN designed a small tank below the centrifuge, together with half height as the standing frame. The small tank could be a catch tank for holding the discharge liquid. While transportation the solids discharge chute can be folded between the tank and centrifuge. The tank is open top for easy observation and to clean. Near to the bottom, there is a port as drain port.

GN Separation will attend 27th Mining World Russia Expo in April

In the coming April, the 27th Mining World Russia will be held in Moscow. GN Separation will attend this fair, brining GN Mining Vibrating Screen and polyurethane screen panels.

Mining vibrating screens can be regarded as a large group, including several different types. Dividing by size, there are small models, middle size models, and large ones. Based on different structures, there are stack vibrating screens, linear motion vibrating screens and banana screens. Depending on the functions, there are vibrating screens for classification, for beneficiation, for dewatering and etc.

This time, GN Separation will bring to the exhibition a stack vibrating screens and screen panels.

1. Stack vibrating screen’s structure:

Stack vibrating screen is a self-designed equipment of GN Separation. It is called stack, because it can be made with 2 to 5 layers, and the exact layer number depends on the job site requirement because each layer has the same screen size and equipped by exactly same screen opening sizes.

2． Features of stack vibrating screens:

The material will enter each layer equally and to be separated at same time and to be discharged under same condition. And the products after separation are collected together. In this way, the separating capacity is doubled, tripled and even quadrupled in a limited space. It is also economic to use a stack shaker when considering the consumption of energy, cause all those screen layers are sharing 2 sets if vibrating motors.

3. Function of stack vibrating screens:

in fact, all mining vibrating screens are suitable for more than one function as the working principles are same. Stack vibrating screens are mostly used for wet separation, classification and fine grained material separation in a mineral processing.

Along with stack vibrating screens, GN Separation will also bring polyurethane screen panels to the exhibition.
