Theyusedtheconcurrent ball milling methodto embed CNTs intoXSBR latex. The samples wereball milledfor an optimized time of 6 h and then dried at a temperature of 40°C in an oven for 48 h. To eliminate the possible effect of other ingredients on the microstructure of the XSBR–nanotube nanocomposite, the samples were prepared free of any extra materials generally added torubber latex compounds.
Planetary ball millis a most frequentlyusedsystem formechanical alloyingsince only a very small amount of powder is required. Therefore, the system is particularly suitable for research purpose in the laboratory. Theball mill systemconsists of one turn disc (turn table) and two or four bowls.

Ball millscan beusedto further break down or refine a single material, or you can place multiple materials into aball mill jarto mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes.Ball millsbasically function like a mortar and pestle, but on a much larger scale.

To accelerate the math or calculation you canusethe shortened formula:Dm <= Km * d^0.5where Km =6 (log dk) is taken from Figure 5 according to the fineness of the finished product dk. These formulas are applicable to the case of feeding a mill with only single-sized balls and not a mixture without consideration for ball wear.

Laboratory mills, used primarily for sample prep prior to analysis, use particle size reduction (comminution) to grind or homogenize wet, dry, hard, soft, elastic, brittle, and fibrous materials. Mills and grinders are used in labs in widely varying scientific areas, including chemistry, pharmaceuticals, food analysis, materials testing, and life science.
