In other side, I find too large the reduction ratio (4000/40 um) for this Vertimill application so with cyclones the overflow will report coarse particles with maximum size around 500 um (P100) which content mainly silica compounds affecting iron concentrate quality.
VertiMill Sizing Example Mineral Processing Metallurgy. 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

MinasRio Project, Anglo American property, located in Brazil, considers Vertimill ™ to make the particle size distribution adequate to feed slurry pipeline. A pilot test campaign was carried out at 's pilot plant facility located in York city, Pennsylvania State, USA, to provide information to scale up the industrial grinding circuit.

Size reduction by crushing has a size limitation for the final products. If further reduction is required, below 5 20mm, grinding processes should be used. Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition.
size distribution, prevent over grinding, and reduce the circulating load from the cyclone. Vertimill Operational Control Final product size is a factor of applied grinding power, flowrate, and slurry density. The effective operation of the Vertimill requires these parameters to be accurately and constantly monitored and adjusted
The Vertimill® design was based on modelling and simulation techniques. Laboratory tests data were used for the scaleup of Vertimill® size reduction performance. During and after commissioning ...

The tests were carried out considering the same media size distribution as that used in the Vertimill™ pilot samples were ground for four different time intervals in dry basis and one test in wet basis was carried out considering an interval time 30% less than the last grinding interval in dry basis.
• Feed to Flotation (Vertimill circuit cyclone overflow ) was more stable • Flotation Feed particle size distribution was steeper than without the Vertimill circuit operating • 24% recovery improvement from previous operation without the Vertimill, largely a result of a finer feed to flotation.

This was a case study for an expansion of a 2200 TPD SAG Mill operation. The client wanted to increase the plant to 2700 TPD 30um. Some plant samples were taken, work indexes obtained and data simulated. As it turns out a single 3000HP Vertimill would get that done. The applications of the VERTIMILL continue to expand in number. The variety of applications being tested and operated are ...
The square symbols represent the measured particle size distribution obtained in the Vertimill ™ pilot test product stream and the solid line is the corresponding model response using the parameters determined and power scaleup.. 4 Conclusions. The simulations indicated that it is possible to predict the particle size distribution and the net power of a Vertimill ™ using population ...

The first 3000hp Vertimill, known as the VTM3000WB, 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.
As a case in point, the VERTIMILL® grinding mill has been cited in a couple of papers (Nesset et al., 2006; Mazzinghy et al., 2012) as being some 35% to 40% more efficient than ball mills for fine grinding with the same ore and size distribution.
