Hard Rock Mining Equipment for Minerals

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, mainly those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds. In contrast soft rock mining refers to excavation of softer minerals such as salt, coal, or tar sands. Hard rock mining equipment is important and essential for minerals processing. In hard rock mining procedure, probably the most commonly utilized tough rock mining gear is jaw crusher, cone crusher, hammer crusher and ball mill, sand making machine, ultrafine grinding mill, and so on. when equipping with auxiliary gear such as vibrating feeder, vibrating screen.It’s generally a complete production line for hard rock mining.

Minerals Hard Rock Processing Line

Large hard rock are fed towards the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. Jaw crusher is used in primary crushing station. It can crush hard rock into smaller sized sizes. Thus, these smaller rocks may be fed into grinding mills for instance a ball mill for grinding.
Soon after the first crushing, the material will transfer to cone crusher or grinding mill by belt conveyor for secondary crushing; the crushed tough rock will then transfer to vibrating screen for separating. Soon after separating, the particles that could meet the specifications will probably be discharged as final items, when the particles below requirement will likely be returned to cone crusher, therefore forming a closed circuit. Size of final items might be combined and graded in line with your specific requirement.
