lack of size reduction by impact, the Vertimill ball consumption is much lower than horizontal Ball Mill. Figure 1: Vertimill Components and Features. Vertimill Applications in the Mining Industry . To date there are a total of 430 Vertimill installations processing different types of ores ranging from metallic to industrial minerals.
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 ).
This provides up to a 40% higher energy efficiency. With the Vertimill® simple and robust design, limited liner replacement is required. This also allows for up to 95% or greater uptime for more productivity and profitability. Versatile applications Vertimill® has proven to be a versatile tool that exhibits many advantages over traditional ...
For instance, the Vertimill® generally uses spherical grinding media in a size range that varies from 6 to 38 mm, depending on the ore and machine [4]. ... Being able to maintain the fineness of grind, this endofscrewlife operation alternative would likely have the disadvantage of increased ball consumption due to wear. However, since it ...
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 first 3000 HP (2240 kW) 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.
Mechanically, the Vertimill is a very simple machine with an agitating screw suspended into the grinding chamber, supported by spherical roller bearings, and driven by a fixed speed motor through a planetary gearbox. Figure presents a schematic diagram of the Vertimill®.
In fact, in the same application a Vertimill® has 50% less footprint than a ball mill. Lower operating cost 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. This provides up to a 40% higher energy efficiency.
1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powderlike structures. 3.
The Vertimill™ is a vertical agitated media mill with a doublehelical steel screw agitator located centrally in a vertical cylindrical screw agitator lifts the media and circulates it throughout the mill. The higher efficiency of the Vertimill™ is due to the higher frequency of lower energy impacts and, by the same token, smaller frequency of higher energy impacts when compared ...
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.
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.
