Grinding method for producing nano-grinding material from input material e.g. fireclay, involves continuously grinding input materials into powder having grains in nanometer range, and discharging ground material by duct
The method involves placing (120) input materials in a drum mill with a loose ceramic-based grinding tools. The input materials are grinded continuously (130) into powder having grains in the nanometer range. The grain size is set between 300 nm-500,000 nm. The grinded powder is dried. The ground material is discharged (140) and separated into three fractions by a duct. An independent claim is included for grinding device for producing nano-grinding material from input material.
