In comparison with conventional ball mills, Attritors use fewer resources, including: Time, Energy, Media Plant Space In addition, Attritors offer the advantage of being able to take samples at any time and making formulation adjustments during high energy ball milling. Alternatively, ball mills are closed systems and do not offer these advantages.

As you can see, for specific energy input around 100 kwh/T, the median particle size achieved through the use of Attritors is nearly 1/2 smaller than that obtained from conventional ball mills, and is about 1/3 smaller than that obtained from vibratory mills.

The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater mediamaterial contact area. Additionally, the attritor mill works at a higher rotation speed up to SPEED. The power input in the attritor is used directly for agitating the ...

milling processes, viz. planetary ballmilling and attritormilling, were employed to investigate the asmilled and sintered microstructure of the W7 wt.%Ni3 wt.%Fe (now onwards referred to as W7Ni3Fe) alloy. Thus, the focus of the present paper is to compare the milling behavior in the two types of mills and understand the

The milling time decreases with an increase in the energy of the mill. For example, a process that takes only a few minutes in the SPEX mill can take hours in an attritor and a few days in a commercial mill.

What is the benefit of using a ball mill over a 90 deg spot drill or a chamfermill that can produce an exact 45. Not that producing a 45 is imperative...I just don't quite understand why adding another variable is a better choice. I see a ball mill adding to complexity as it can touch at many angles giving inconsistent results over an angled tool.

The Attritor is a grinding mill containing internally agitated media. It has been generically referred to as a "stirred ball mill." A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills.
