Procedure for treatment of clay used especially for making bricks

摘要

Rough clay(1) is first coarse ground in a coarse grinder(2), water(4) and possibly a liquifying agent(7) added to it, and then fine grinding carried out in a fine grinder by dispersion of the coarse ground clay in the added fluids. Consequently, a cream(5) of clay is produced and impurities removed by sieving. The cream is then dried and the dried material collected in a collecting receptacle(6).
