With increasing speed of the ball mill from 200 to 400 rpm at a fixed milling time of 30 h, the particle size of the milled powders decreases gradually till it reaches a saturation value. This observed result agrees with a mathematical model that describes the dependence of post-milling particle size on the rpm of a mill.

According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill, L/D ≥ 1–1.5 or even 2–3; and tube mill, L/D ≥ 3–5. According to the cylinder shape of the ball mill, it can be divided into cylindrical ball mill and cone ball mill.

Photoreforming of cellulose is a promising route for sustainable H2 production. Herein, ball-milling (BM, with varied treatment times of 0.5–24 h) was employed to pretreat microcrystalline cellulose (MCC) to improve its activity in photoreforming over a Pt/TiO2 catalyst. It was found that BM treatment reduced the particle size, crystallinity index …
