Grinding Media Optimisation

GSL has developed a market leading approach to ceramic grinding media testing which has been formulated over decades of working within the industry. A wide range of laboratory stirred media mills, combined with the detailed knowledge and expertise of fine and ultrafine grinding creates unique and unparalleled independent testing services.

Our continuous open circuit grinding media testing provide an industry leading approach to produce accurate and reliable data on the wear performance of ceramic grinding media in relation to specific operating conditions. Our procedures can be used to provide answers quickly to the following:

  • Identification of performance related issues
  • Quality control testing
  • Independent, comparative grinding media wear and performance testing
  • Grinding media selection optimisation
  • Process verification testing

Testing can be carried out using client-supplied feed samples, to replicate plant conditions, or using a standardised silica flour. Media wear analysis is carried out in terms of wear rate, changes in media size and shape (using our ZEISS microscope), grinding efficiency and mill power draw.
