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.

The pulp density is an important parameter which influences the grinding efficiency. In iron ore for instance a variation of 2 to 3 solid content in the slurry could lead to a difference up to 10 on the energy kWhT for a similar grind. Optimization of mill performance by using online ball and pulp measurements J o u r n a l P a p e r
Dec 01 1989 In the present work various operating parameters such as stirring speed pulp density and the use of grinding aids have been studied using a laboratory stirred ball mill. It has been found that the mill operates most efficiently at low stirring speeds and high pulp densities as long as the viscosity is controlled within limits.
A ball mill is a type of grinder used to grind materials into extremely enormously increasing surface area and reaction rates. The grinding works on the principle . US Patent 4404640. Grinding mill monitoring . In grinding mills such as ball variable conditions exist affecting flow grinding or output the ball mill .

Jun 23 2020 Grinding mills including SAG semi-autogenous grinding mills and ball mills consume approximately 60-70 of the total energy cost of the entire mining operation. The mills are installed with large motors up to 20MW which impart the required energy to successfully process many tonnes per hour and grind the rock to a powder size suitable .
The influence of various operating parameters can be combined into the stress intensity which describes the capability of a stirred media mill. Operating parameters also have an influence on the magnitude of force magnitude between grinding media which will result in
Usually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
