Sedlecký kaolin

We supply most of the kaolin in the form of lumps. We transform them into powdered kaolin by grinding and drying. We ship unpackaged kaolin in batches of 20 to 50 tons on wagons and trucks. Part of it is supplied in big bags weighing from 500 to 1200 kg. For smaller consumers, we prepare kaolin in paper bags weighing 25 to 45 kg.

The ISO brightness of the kaolin sample after SHGMS was improved from 56.9% to 76.7%. The D50 value of the magnetic rejects was 35% larger compared to the feed. Large particles might block the micro-pores in the steel wool matrix. Compared to the feed, the dark or red impurities significantly decreased in the non-magnetic product.
