EXCELLENCE IN SEPARATION TECHNOLOGIES

Magnetic Separators

Project Detail

BGRIMM-MAT Magnetic Separation technology is Leading the development of Magnetic Separation technology in China and is China’s largest supplier of Magnetic Separators with permanent magnets.

The Beijing General Research Institute for Mining & Metallurgy (BGRIMM) have been active in Magnetic Separation Technology  research, design and manufacture since the early 1960’s. BGRIMM-MAT (Machinery & Automation Technology division) is Asia’s leading Magnetic Separation technological development company who design equipment for over 70% of the Chinese market.

Recently BGRIMM have supplied  major mining operations such as Sino Iron in the Pilbara region in Western Australia with 200 BGRIMM units successfully installed in the plant.

Apart from the Chinese market, BGRIMM have supplied numerous Magnetic Separators for different applications in Australia, Peru, Saudi Arabia and Kazakhstan etc.

Roytec will support BGRIMM-MAT with a range of services including testwork, equipment sizing, project execution to western standards.  In addition, Roytec offer commissioning, after sales service and local spares holding.

The combination of BGRIMM’s leading technology, economical Chinese fabrication and strong local support from Roytec gives local clients a very attractive option for their Magnetic Separation needs.
