Granulation and Atomization Process for Production of Metal Granules and Powders
The Processing of metal lumps into granules and powder is a challenging task in the modern manufacturing industry. Some valuable metals like silver and gold are facing difficulty while processing them for granules and powers. The major difficulty faced during the granulation with conventional process is irregular dimensions with very less yield and the process is time-consuming too. The granulation process involves the breakage of a large lump in to small granules after melting of metals and pours them in the coolant. During this process, metal get melts in a furnace and pour into water with minimum orifice diameter. The metal falls within the water, which allows it to get cool at room temperature. This process is to be carried out in a vacuum, and the process known as primary atomization. To get the further breakdown of granules in to powder we have to follow the impinging of poured metal before sediment in to the water is needed. This disintegration process involves the breakage of a metal droplet into the microns size by using the high-speed gas jet. This research article presents granulation and atomization process and demonstrate that how we can achieve 100% yield of valuable metals by using proposed technique. The experimental results showcase the effectiveness of the developed process.
