Ball-milling: A sustainable and green approach for starch …
Abstract. Ball-milling is a low-cost and green technology that offers mechanical actions (shear, friction, collision, and impact) to modify and reduce starch to nanoscale size. It is one of the physical modification techniques used to reduce the relative crystallinity and improve the digestibility of starch to their better utility.

3.2. Effects of ball milling on biochar's physicochemical properties3.2.1. Increase of surface area. The specific surface area of the BM-biochars were all greater than that of their precursors (corresponding unmilled biochars, Table 1).The unmilled biochars produced at 300 °C had very low surface area (0–2 m 2 /g), which is common for …
Graphite functionalization by ball milling with sulfur
The present study reports on ball-milling of high-surface-area graphite in the presence of sulfur, mainly considering high graphite/sulfur (G/S) weight ratios. Graphitic crystallites after co-milling with sulfur maintain essentially unaltered crystalline order while exhibit heavily functionalized lateral edges, mainly by O=S=O and S=O groups. Solvent …

The high-resolution SEM images show the different morphologies of four samples. Starting commercial graphite (Fig. 1a, C 1) had a flake-like shape.Annealing treatment did not change this morphology, as shown in Fig. 1c, C 3.However, ball milling treatment has changed the morphology substantially of C 1.There is no typical flake-like structure in the …
Ball milling as a synthesis method
Introduction. Ball milling is generally known as a method to mix, blend, shape and reduce particle sizes. It can also be used as a mechanical synthesis method to produce materials that are milled to extremely fine powders. Several factors, like milling temperature, type of mill, milling speed etc. need to be considered when using ball milling ...

Ball Mill
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
