Vertimill Vertical mill wet for coal grinding for Vertimill is the industry benchmark in stirred milling technology Globally recognised as energy efficient grinding machines they bring substantial improvement in profitability of concentrators
Vertimill is an energy efficient grinding machine They tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns has recently developed a 4500 HP 3352kW Vertimill designated the VTM4500C the vtm 3000 wb vertimill grinding mill specificatio
In this context a study was initiated to assess not only the performance of a Vertimill grinding circuit processing a copper concentrate to a particle size of 80 passing 17 µm but also to provide Taseko's New Prosperity project specific design information for grinding to particle sizes below 80
6 Stirred Milling The Vertimill is typically arranged in closed circuit and fed by the cyclone underflow The motor power turns the Vertimill screw at constant speed to stir the grinding balls and slurry As the particles are ground they rise to the top of the mill and overflows into the separating tank
STIRRED MILLING TECHNOLOGY Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads The stirring effect is caused by rotating discs mounted on a shaft
Vertimill VS Ball Mill 14 replies To get energy efficient grinding below approx 40 µm you need to have finer grinding balls than are suitable for the tumbling mill So the case for the stirred media mill that often has media in the range 510 mm if used as a tertiary grinding step or for regrinding
VERTIMILL Grinding Mills Stirred Media Detritor Typical Grinding Ranges Ball Mills and stirred mills are applied across a wide range of appliions but for each ore there is optimum efficient range The figure to the left shows the typical appliion ranges for ball mills and stirred mill The Vertimill is always more efficient than a ball mill
The VERTIMILL initially was developed to meet the needs of the fine grinding industry It has been expanded to include coarse grinding in copper lead zinc gold aragonite calcium carbonate plants
