    Increase throughput and capacity in SAG mills

    The loudest silence occurs when your SAG mill is standing still. It is the sound of rising costs by the hour both from the downtime itself and from maintenance costs. Optimising the capacity of your SAG mill is crucial to avoiding downtime and liner wear and damage. With variances in mill ore feed rate, mill speed and slurry density, critical impacts can occur in your SAG mill.

  • Modification and optimization of SAG mill shell liner

    Modification and optimization of SAG mill shell liner

    Once the lifting strip is worn off, the liner will not only lose the lifting effect on the material, but also aggravate the sliding between the material and the liner, and the liner will be worn out quickly, damaging the mill barrel. There are many factors that affect the service life of the SAG mill shell liner, including the liner structure ...
