  • Material recycling of inorganic slag by wet ball milling

    The fractions of CaO and Fe2O3 in the specimens obtained by wet-ball-milling the simulated waste slag powder decreased that of SiO2 increased and those of Al2O3 and Na2O hardly changed. These specimens contained 0.10.8mass ZrO2. Appropriate solution and time for wet ball milling were 300 ml distilled water and 20 h respectively.

  • Ball Milling for Biomass Fractionation and Pretreatment

    A promising approach in the selective separation and modification of cellulose from raw biomass under a mild alkali process was proposed. In our study ball milling was applied to wheat straw prior to alkali treatment. With ball milling ultrafine powder formed an amorphous microstructure and displayed a level of solubilization in aqueous NaOH higher than that of general ground samples. Alkali
