Ball milling and subsequent annealing is a simple method for the production of CNTs. Although it is well established that mechanical attrition of this type can lead to fully nano porous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders by thermal annealing.Module7 unit3 NSNT Module 7 Ballmilling,Figure 1 Schematics showing nanoparticle synthesis via ball milling method. In highenergy milling, the powder mixture is subjected to highly energetic impact. Microstructurally, mechanical alloying has four stages: a. Initial Stage: Initially, compressive forces from collisions of balls flatten the powder particles.

Ball milling is generally known as a method to mix, blend, shape and reduce particle sizes. It can also be used as a mechanical synthesis method to produce materials that are milled to extremely fine powders. Several factors, like milling temperature, type of mill, milling speed etc. need to be considered when using ball milling
The ball mill is a popular tool choice amongst mechanochemical researchers. Widely available in a variety of sizes and designs, these devices contain one or more loose balls that crush whatever is inside them as the vessel is shaken or rotated. Both compressive and shear forces are put on any molecules inside.The operating principle of the ball mill ,The operating principle of the ball mill consists of following steps.

Construction of Ball Mill. The ball mill consists of a hollow metal cylinder mounted on a shaft and rotating about its horizontal axis. The cylinder can be made of metal, porcelain, or rubber. Inside the cylinder balls or pebbles are placed. The balls occupy between 30 and 50% of the volume of the cylinder. The diameter of the balls depends onGBT 38064 球磨粉磨系统 矿物物料易磨性试验方法,ICS 73.120 D 94 中华人民共和国国家标准 GB/T 38064— 球磨粉磨系统 矿物物料易磨性试验方法 Ball mill grinding systemTest method for grindability of materials 0501实施 1018发布 国家市场监督管理总局 发布 中国国家标准化管理委员会 GB/T 38064— 前 全球最全的积分文库，可永久免费使用,如文档有侵权请,
