The IsaMill was developed for fine grained orebodies that needed a step change in processing efficiency to be economic. The IsaMill significantly reduces the energy requirement, and media and capital costs of fine grinding.One of the most energy-intensive processes for producing submicron range calcite is stirred media mill. In the present work, numerous operating parameters such as solid mass fraction, grinding media size, media filling ratio, and grinding time have been investigated using a vertical type stirred media mill. The results are evaluated on the basis of mean particle size, specific surface area ...Media, also called ball mills, use balls or spheres to grind, crush, blend and even polish materials while rotating inside a drum or with an internally rotating agitator. This type of equipment is used for media blasting and wet grinding and is found in a wide range of processing industries.
