In recent years, China's metal mining has been committed to energy saving, and improved economic efficiency, and the basic principle is “more crushing, less grinding”. Progress of crushing equipment is mainly in the development and application of original practicality crushing equipment like new external moving jaw crusher. But there is a certain gap between these devices and crushing equipment abroad in technology, use and effects. In addition, Raymond Mill also has a certain application in the domestic part of the mine, because this kind of equipment has a large range of energy saving, so the amount of the system can be increased more than 30%-50%, and the device is with features of high running and low environmental impact.
Although part of China's iron ore beneficiate technology and concentrate quality has reached the international advanced level, but China's iron ore is poor, miscellaneous, fine and a variety of other characteristics. The new requirements of iron ore concentrate from iron and steel industry put forward to new challenges for mineral processing workers in China. Therefore, China's metallurgical beneficiation technology still has deeper development.
In the popularization and application of magnetic separation-reverse flotation, efficient magnetic separation (magnetic re-election) represented by the high-quality iron ore beneficiation technology, beneficiation process should be as efficient and simple. Therefore, we should enhance beneficiation equipment and beneficiation process as much as possible to achieve the best results in the most suitable process and beneficiation process should be as efficient and simple.
