Process for producing burnt materials, particularly burn kaolin

摘要

The process for producing silicate clay materials, especially calcined kaolin and mixtures thereof, clay and fillers in granular or ground form, is carried out by firing in the furnace to the ceramic carrier. First, the molded ceramic carrier made of a material selected from the group consisting drolenku or testo kaolin, clay, grog, alumina grog, washed kaolin, washed kaolin with increased content of alumina, titania or magnesia, or a mixture of these materials, then dried and then are fired simultaneously with the silicate material in a furnace and then after firing is taken burned silicate material in the form of granules and powders from ceramic carriers as a burnt silicate product allyl ceramic carrier was crushed and / or milled for use as a second burnt silicate product. Contents of ceramic carriers not to be crushed after firing, eventually. Grind and thus this procedure can replace the so-called nonferrous fine grinding. The ceramic carriers with embedded silicate material being burned to the desired firing temperature up to 1600 degC. The ceramic supports may have a tubular shape tvarnebo enclosure respectively. Bathtub kiln car. Pálenýmateriál ceramic carriers after grinding or crushing can be mixed with burnt silicate material.
