Ultrafine dispersion grinding for paper or wall paint as filler.
The production of coated paper requires carefully controlled mineral pigments and fillers to achieve consistent coating quality, smoothness, opacity and print performance. Materials such as calcium carbonate and kaolin often require fine or ultra-fine grinding before they can be used in paper coating formulations.
◎Grinding Challenges in Paper Coating Materials
