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.

Vertimill®. Longlasting wear life with Orebed™ The inside and the door of your Vertimill® are protected by Orebed™ linings. Orebed™ consists of a series of powerful magnets embedded in rubber. The ferromagnetic material in the mill load forms a layer that protects the lining. Installing Orebed™ is fast and easy since no bolts are needed,
Vertical Mills Gain Size While Drives Get Simpler Vertical Mills Gain Size While Drives Get Simpler reduce or eliminate the usual requirement of installing several vertical mills to accomplish the same grinding task that can typically be done by a single ball mill.
There was four main ways the treaty of versailles contributed to ww2 and one of them was territorial losses. During the ww2 germany lost some land but they also lost one of the biggest port city (Doc A). When you lose the biggest port city/land you wont get lots of trade. Without trade you won't get money.

The VERTIMILL® (VTM) is a low intensity stirred mill with a tip speed of 3 m/s. These have been installed in a wide range of secondary, tertiary and regrinding duties receiving feed from AG, SAG and ball mills. More than 400 VertiMill® have been installed globally with total installed power of 227 MW.
Fig. 1. TowerMill® (Eirich courtesy) and Vertimill™ ( courtesy). The vertical mills have a large vertical doublehelical steel screw agitator located centrally in a vertical cylindrical shell. The agitator rotates and stirs the media while simultaneously lifting and circulating it throughout the mill ( Morrison et al., 2009 ).
VertiMill Sizing Example. 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.
