Ball mills are a type of machine used in the food industry. In these, a ball performs the process of grinding raw inputs down so that they are maximally uniform. The ball moves inside the working chamber according to a set or random pattern. These mills are used in the confectionary industry for producing chocolate, glazes, and homogeneous fillings (e.g. for candies and chocolate bars). They are intended for use with products of a liquid or paste-like nature. They provide significant energy savings, and their distinctive design saves floor space. Control of these machines is fully automated.
