  • Stirred Milling Technology – A New Concept in Fine

    High power intensity and energy efficiency In stirred media grinding, the energy intensity (kW/m³) is very high versus tumbling mills In the HIGmill the power intensity (installed) is typically 180 to330 kW/m³ This means a very “packed” process: ie, high throughput and/or high SGE in a small unitThe HIGmill™ comprises a mill body, shaft with grinding discs, shell mounted counter rings, gearbox, and drive The grinding chamber is filled up to 70% with grinding beads Rotating discs stir the charge and grinding takes place between beads by attrition The number of discs (grindingHIGmill high intensity grinding mill minevik OutotecStirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the product They are suitable for both openStirred mills for wet grinding minevik Outotec

  • Vertical stirred mill scaleup and simulation: Model

    Vertical stirred mills are typically loaded with smaller media, and part of this extra efficiency would be due to the increased specific surface of the smaller media and, consequently, an increase in the grinding action, especially for smaller particles (Mazzinghy et al, 2015a)A small change in efficiency can lead to substantial benefits in an overall economy of the process plant This study focussed on the comparison of vertical stirred mill agitator(PDF) A Comparative study on a vertical stirred millachieve efficient grinding, closed circuit with hydrocyclones is needed High cyclone efficiency greatly improves the performance of the circuit A new procedure for Tower mill simulation and scaleup has emerged recently Introduction The Tower mill is a vertical stirred grinding mill which can be used in both dry and wet grinding applicationsTOWER FINE MILLING EXPERIENCE AT MOUNT ISA MINES

  • Impact of the stirred mill grinding mechanism on the

    11 Grinding mechanism of a vertical mill with vane rotors STM/Outotec’s HIGmill™ is a “stirred media” grinding mill where the stirred effect is caused by rotating vane grinding discs (rotors) together with stator rings situated on the shell"The successful introduction of new high intensity stirred milling technologies (eg IsaMill, SMDetritor) to the mining industry in recent years prompted NorandaFalconbridge to initiate a study comparing these technologies to the conventional technologies of ball milling and existing vertical stirred mills (eg VertiMill)Assessing the Performance and Efficiency of Fine GrindingThe popularity of stirred media mills has risen in recent times CITIC HIC has developed our own range of vertical stirred media mills to complement our conventional grinding mills range, research and development team in Australia and CHina constantly working improving technology and efficiency ofVertical Stirred Mills (CITIC Stirred Mills CSM) CITIC
