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.
