They are wary of grinding products as mixes, it is often better to mill hard and soft powders separately and combine them later. Engineers typically use surface area measurement instrumentation to evaluate mill efficiency. Ball mills can reduce particles to the nano sizes, the process is very important in creating powders used in hi-tech ...
The mill oil consumption continued at a slightly reduced rate and numerous mill shutdowns were taken to visually inspect the journal surface for crack propogation or the existence of new cracks. A new mill discharge head was ordered with a 16 week delivery.

Ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle, but on a much larger scale.
Shot peening is a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metals and composites. It entails impacting a surface with shot (round metallic, glass, or ceramic particles) with force sufficient to create plastic deformation.. In machining, shot peening is used to strengthen and relieve stress in components like steel automobile ...

Carbon steel weld covered in paint Defects Found in Carbon Steel Cracking. Cracking is the most prevalent type of defects in in-service carbon steel welds. Cracks come in various shapes and sizes, from surface-breaking cracks to stress-corrosion cracking (SCC).
A smaller ball interpolated exposes more of the surface to a faster moving cutter, leading to a better finish. But, the smaller cutter can flex more. Hence the need to balance these two factors. If you have a 4th axis or 5-axis mill, you can try "Sturz" milling to combat the slow moving tip. See below for details.
Example applications include examinations of pipelines, bridges, engines, aerospace structures, and any conducting material for surface breaking flaws including cracks. In addition, model-based methods are being used to size cracks accurately found in the addendum, dedendum, and the root of kiln and ball mill girth gear teeth.
