The effect of dry state and solvent-assisted on morphological and structural changes of microcrystalline cellulose were investigated. The structure changes, including particle size,Apr 01, 2020 The adsorption capacity of HWBM300 to acetone was 92.0 mg/g, which is 13-fold higher than that of HW300. Because the ball-milling modification mainly increased the external surface area of the HWBM300, the dramatically increased acetone adsorption could not be solely attributed to the enhanced SSA after the ball milling.

  • Effect of aging and ball milling on the phase

    Effect of aging and ball milling on the phase

    Ball milling is a process for grinding materials into fine powder. Grinding balls are mixed with the material in a container. Spinning the container reduces the mate-rial into powder form through rubbing and tumbling of the balls against the material. In planetary ball milling, the grinding bowls rotate around their own axis as theyballs and mills were used for milling Cr and Ni powders. In addition, because of the corrosive nature of the acetic acid used in one of the runs with Cr powder, Cr balls in a molybdenum lined mill were used. Unfortunately, the Cr balls became available too late in the program for use with all the milling …
