    The total energy consumption for ore comminution will further increase within the next decades. One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle.

  • Mineral processing

     &#; Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.

  • Cast Grinding Steel Balls

     &#; The lower impact forces are due to a combination of both smaller ball masses and lower drop heights resulting from the use of smaller balls and smaller mill diameters, respectively. The feed ore in primary grinding mills is typically very abrasive owing to its particle size, shape, and mineralogy.
