In this study, silica nanoparticles (SiO2 NPs) were fabricated using a handmade ball mill as a novel, simple, rapid, costeffective, and green approach. The solgel method was also used to produce these NPs as a comparative method. The SiO2 NPs produced by both methods were characterized using highresolution transmission electron microscopy (HRTEM), dynamic light scattering (DLS), energy ...

size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 monosizes namely 8 mm + mm, 4 mm + mm and2 mm + mm for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted. It was

Unlike the ball mill, there is no grinding medium is used in the fluid energy mill for the size reduction of the materials. Due to the expansion of the gas in the chamber, temperature in the mill decreases which enables the use of the fluid energy mill for the milling of thermolabile substances (Lachman et al., 1987 ) (Fig. ).

For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.

ceramics as well as selective laser sintering. The working of a ball mill is based on impact and attrition: the impact, caused by the balls dropping from top of the shell, breaks down the particles, thereby resulting in reduction in size. Ball mill includes a hollow cylindrical shell which is rotated about its own axis. The

The objective of this experiment is to study the concept of size reduction using ball mill. In order to reduce the size of particles efficiently, the speed must be controlled so the load closest to the cylinders' walls will break, and other particles in the upper curves will shortly follow, forming a sliding stream containing many layers of ...
