The first 3000-hp Vertimill, known as the VTM-3000-WB, is destined for Newcrest Mining Ltd’s Cadia Valley Operations, where it will be operated in a tertiary grinding role Cadia’s concentrators in New South Wales already have several Vertimills (VTMs) operating in traditional regrinding roles, as well as a VTM grinding SAG product in parallel with a ball mill
Since its introduction in the late 1970s, close to 420 VERTIMILL grinding mills have been sold worldwide states: “The high-capacity vertical grinding mill has proven to be a versatile tool that exhibits many advantages over traditional ball milling
A continuous grate-discharge tumbling mill with grinding balls does seldom have ball size below 20 mm since you then will have unacceptable media losses or problem with grate throughput To get energy efficient grinding below approx 40 µm you need to have finer grinding balls ,
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 VTM-4500-C
Sep 05, 2013· In comparison to traditional ball mills, in fine and regrind applications, the VERTIMILL® mills can perform the same grind with 30% to 50% less energy and significantly lower grinding media .
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 Modes of Operation A Closed circuit with feed directly into VERTIMILL and VERTIMILL discharge to a cyclone feed sump
Vertimill™ has been used in regrind circuits during the past years due to its greater efficiency when compared to the conventional tube ball mill This 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 100% to
Ball Mill Vertimill® SMD 100000 10000 1000 Microns 100 10 1 Mill Ty pe Typical Grinding Ranges Ball Mills and stirred mills are applied across a wide range of applications, but for each ore there is optimum efficient range The figure to the left shows the typical application ranges for ball mills and stirred mill The Vertimill is always more .
Vertical ball mill slakers are grinding mills commonly used in the mineral processing industry for fine grinding applications, modified to withstand the temperature of lime slaking Vertical ball mills are simple and rugged and have the safety advantage over their horizontal equivalents of ,
The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machin The Vertimill energy savings range from 30% to greater than 50% compared with traditional ball mills and the SMD energy savings are far greater than 50% of ball mill energy in fine .
VERTIMILL ® The VERIMILL ® lime slaker is rightfully earning the reputation as the best approach to ball mill slaking in the industry Robust, mining duty design and construction, the VERTIMILL ® is the right choice when your application requires grit to be ground and retained in the lime slurry, rather than being screened .
