In October 2003 a Vertimill®, for secondary grinding, was commissioned and the lead and zinc flotation cleaner capacity was increased. This enabled the production rate to increase to its current level of million wet tones per annum with minimal capital expenditure. The Vertimill® design was based on modelling and simulation techniques.

Slaking occurs when quicklime is reacted with water to form Ca (OH) 2, most commonly called hydrated lime in its dry form or lime slurry or milk of lime in its wet form. The slaking process is exothermic, releasing heat as the quicklime and water mix and chemically combine. A lime slaking system that is not running at its peak could be unsafe ...

The figure to the left shows the typical application ranges for ball mills and stirred mill. The Vertimill is always more efficient than a ball mill with energy savings ranging from 30% to greater than 50%. The transition point from the Vertimill to an SMD varies depending on the ore properties but generally is in the range of 20 to 40 microns.

Problem: Difficulty accessing the VTM screw during removal and installation. Placement of surrounding equipment near the mill often reduces accessibility for maintenance. After the VTM is installed at site, there is often additional steelwork, platforms, and walkways, etc. that are constructed or installed in front of the VTM or above the door.
