    According to Vilela, the granulometry of the iron ore in the MinasRio System at the end of the regrinding process is 80% less than 36 micrometers The iron ore from the underflow of the regrinding cyclones feeds the Vertimill grinding mills through the lower part and the resulting product is transported to the top of the mills, towards theThe VertiMill® is preparing the feed for flotation at lower specific energy • Successful application of stirred mill for secondary and tertiary grinding duty • Reduction ratio plot for stirred mill performance evaluation • VTM receiving feed from AG/SAG and ball mill productVertiMill® – Preparing the feed within floatable regime atThis paper presents the Vertimill™ pilot grinding tests with a sample of copper ore carried out in closed circuit with a high frequency screen The sample was crushed(PDF) Vertimill as the definitive step before concentration

  • Regrinding and fine grinding technology the facts and

    A review of regrinding and fine grinding technology the facts and myths Dr Alex Jankovic, minevik Minerals Process Technology AsiaPacific, [email protected] ABSTRACT Stirred milling technology is used extensively for fine grinding in the ceramic, paint and pharmaceutical industrials It has been recently adopted by the mining industryHi, I have the following situation: Magnetite ore with a work index wi=102 kWh/t feed= 100t/h f80= 4000 microns p80= 40 microns The question we have: is possible for just a single VM 3000 and cyclones to handle this condition + the circulating load? According to my preliminary is aEstimate Vertimill Capacity Grinding & ClassificationA versatile and energy efficient solution minevik Vertimill® is the industry benchmark in gravity induced milling technology Globally recognised as efficient grinding machines, they bring substantial improvement in profitability of concentrators Up to 40% higher energy efficiency 95% or greater uptime 50% less footprint vs ball mill (In sameminevik Vertimills® minevik Corporation PDF Catalogs
