Swiss Tower Mills Minerals AG (STM) supplies the VRMmill™ (Vertical Regrind Mill) also known as the High Intensity Grinding mill (HIGMill™ used by Metso, who entered into an exclusive technology agreement to market STM’s VRM type mills in 2012) for fine and ultrafine applications.

The VRMmill™/HIGMill™ concept is derived from the industrial minerals sector and finds its application in metalliferous projects globally. With vertical configuration, the mill features high grinding intensity from numerous castellated grinding rotors comparted by neighboring counter-mounted static rings. The unique mill design and its grinding efficiency makes fine and ultrafine grinding an economically feasible option.

The VRM5/HIG5 is a laboratory test mill that can be employed to mainly obtain the Specific Grinding Energy (SGE) for certain milling duty for mill sizing purpose. The VRM5/HIG5 testing services that Kings provides include:

  • Specific Grinding Energy (SGE) required to reach the targeted product size (i.e. P80), which is also known as “Signature Plot Testing”.
  • Comparison of ceramic media wear rate for VRMmill™/HIGMill™ applications.
  • Optimizing grinding conditions for VRMmill™/HIGMill™ applications, in terms of ceramic media selection, energy efficiency, and target product size distribution of the ground product.

As VRMmill™/HIGMill™ recommended ceramic media supplier, King’s is always ready to offer a total grinding solution package for your VRMmill™/HIGMill™ application.
