Ball milling: a green technology for the preparation and
The formation of cellulose crystals by ball mill assisted hydrolysis was also reported by Tian and co-workers, who described the preparation of microcrystalline cellulose (MCC) from eucalyptus pulp by mercerization and subsequent ball mill treatment. 44 The pulp was first treated with sodium hydroxide, then milled in the presence of the same at 450 rpm for 5 Ball milling is a simple, fast, cost-effective green technology with enormous potential. One of the most interesting applications of this technology in the field of cellulose is the preparation and the chemical modification of cellulose nanocrystals and nanofibers.

Fig. 3 shows a typical TG-DTA curve of the silica powder modified by 0.5 ml of HTMS after ball milling for 24 h. The DTA curve showed two peaks at approximately 130 and 300 °C. The first endothermic peak corresponds to the loss of physically adsorbed and/or hydrogen-bonded water from the silica powder [22].The second exothermic peak Silica nanoparticles have been prepared by planetar y ball mill method at room temperature at different milling hours using Malpe beach sand, Karnataka, India.

Fig. 4 shows the average bulk density of each sample. The average bulk density of pellets prepared by raw powder is as low as 1.41 g/cm 3.However, the average bulk density increases as the milling time of powders increases, reaching 2.00 g/cm 3 at milling time of 12 h. After 48 h of ball milling, the average bulk density slightly increases 3. Experimental Setup. Ball milling is a method for fine powder grinding and fabrication of submicron or nanostructured powder materials [].Ball mill is used for the purpose of grinding all kind of mines and materials [10, 11].Throughout the years, it has proved to be an effective and simple technique to produce nanocrystalline powders and Process Parameters Optimization of Silica Sand Nanoparticles
