  • Mill Changes Bring Multiple Benefits at Berezitovy Gold

    "After the first four months of grinding gold ore with mill liners in our SAG mill the results are very positive. The wear rate is low and based on the first wear measurement the expected life is about double compared to what we got from our previous all-metallic liners " said Nikolay Vershinin head of the mine s process plant.

  • A comparison of SAG mill power models

    SAG Mill power draw models are used in mill design and grinding circuit modelling to predict how much power will be consumed by a particular mill geometry and operating configuration. This paper will compare SAG mill models by Morrell Loveday (using "Power Numbers" published by Barratt) and Austin against several published mill surveys.
