Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·Iron ore tailing is a major solid waste requiring advanced recycling methods because ore tailing powder is polluting air and water resources For instance about 300 million tons of tailings are disposed yearly in 1229 iron ore tailings dams in the Hebei province in China Iron ore tailings can be recycled as functional materials because these
