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 10 microns. This provides up to a 40% higher energy efficiency.
Regrind Ball Mill. F = 210 micrometers. P = 45 micrometers. Wi = 14.0 W = 10 x 14.0/√45 – 10 x 14.0/√210 = 11.21 kwh/s. ton. Efficiency Factors: EF1 does not apply. EF2 Many regrind operations are closed circuit, but assume this one is open circuit and 80 percent passing grind will be the controlling point. Refer to Table VIII.

Efficiency amplified: The game-changing power of attritor type ball mills. The attritor type ball mill is a unique and versatile machine that is widely used in various industries for the grinding and mixing of materials. It combines the principles of a ball mill and a horizontal agitated mill, resulting in a highly efficient and effective ...
Improving the grinding efficiency in tumbling mills is essential to minimising comminution energy consumption. Over the years, fundamental insights gained from ball mill operation provided energy-efficient routes to increase throughput and reduce product grind size distributions through optimisation strategies.
3. Analysis of Variant Ball Mill Drive Systems The basic element of a ball mill is the drum, in which the milling process takes place (Figure1). The length of the drum in the analyzed mill (without the lining) is 3.6 m, and the internal diameter is 3.4 m. The mass of the drum without the grinding media is 84 Mg.
The importance of classification to ball mill circuit efficiency has been studied and emphasized by many comminution experts through the decades (Bradley, Davis, Heiskanen, Hukki, Jankovic, McIvor). The slurry pump/hydrocyclone combination is, perhaps, the most common classification system equipment selection in
Ball mill = coarse particles (in the plant ball mill) grinding efficiency Ore grindability (in the lab ball mill) The units of "ball mill grinding efficiency" will be covered in detail in the first part of the module. Alternatively, we can say that: Specific grinding rate = …
Therefore, it also represents the overall classification efficiency of the grinding circuit. A simple method for estimating the relative coarse solids inventory in the ball mill has been selected. It is the average of the coarse fraction in the ball mill feed and discharge size distributions.
