Particle size reduction & Particle forming innovations
Milling is a widely used industrial operation common for cases where size reduction of particles is required. It involves the size reduction of particles smaller than 10 mm. There is a vast range of mill types available, such as ball mills, vibratory mills, rod, jet, and cage mills. For a larger diameter, planetary ball mills can be used.
