Assessing load in ball mill using instrumented grinding media

Assessing load in ball mill using instrumented grinding media

Rolf and Vongluekiet (1982) used instrumented ball to measure impact energies in a × m mill, showing that impact frequencies are higher at 55% and 75% critical speed. Gao and Thelen (1994) developed the grinding balls which integrated piezoelectric sensors and dataprocessing electronics to analyze load movement from distributions of ...

Effect of BallMilling Pretreatment of Cellulose on Its Photoreforming ...

Effect of BallMilling Pretreatment of Cellulose on Its Photoreforming ...

Photoreforming of cellulose is a promising route for sustainable H2 production. Herein, ballmilling (BM, with varied treatment times of 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 (CrI), and degree of polymerization (DP) of ...
