Welcome to Visit GN Booth at CIME 2023 Mining Exhibition

In this hot July, there will be an international mining exhibition to be held in Shenyang City, the largest city in Northeast China. The full name of this Exhibition is CIME 2023, the 3rd Sino-foreign Mining Industry Chain Development Forum, which will be held from July 27th to 29th in Shenyang International Exhibition Center.


GN Separation will attend this exhibition, brining GN Vibrating Machines and other equipment used for mining industry.

About GN Separation: GN Separation is sister company of GN Solids Control, a leading brand in oil and gas solids control industry, which is exporting its products to 80+ countries in the world. GN Solids Control is mainly focusing on the drilling fluids solids control and waste management equipment and systems, while GN Separation covers other industries like mining, water treatment, food and beverage industry. Mining Vibrating Screens and Decanter Centrifuge are quite popular products for GN clients from mining industry.

For this CIME 2023, GN Separation will bring following equipment:


1. Stack vibrating screens. Stack vibrating screens are designed by GN team for wet screening, classification and dehydration of fine grained materials in mineral processing, coal preparation and etc. Two or more screen decks are stacked together, with same deck size and openings. The input material will be divided to each deck evenly and the output will be collected together. There is only one energy source for all decks. This design maximizes the usage of both the vibrating motors and the limited room.

2. Dewatering vibrating screen. Dewatering vibrating screen and classification vibrating screen are two kinds of GN middle sized vibrating screens. Their barriers are not so huge between the two kinds of screens. In fact, some clients are using classification vibrating screens for dewatering applications. But GN dewatering screen is more efficient with a slight modification.

3. Screen panels and screen meshes. The screen panels on the dewatering screen and screen meshes on stack vibrating screens are both manufactured by GN Separation. GN vibrating screen panels are polyurethane covered while GN vibrating screen meshes are fully polyurethane.

Welcome to meet GN team at GN Booth BT05 in Hall E3, from July 27th to 29th.

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.
