METHOD OF IMPROVEMENT OF CLAY RAW MOLDING AND DRYING PROPERTIES Russian patent published in 2005 - IPC

FIELD: agriculture; production of ceramic materials on the basis of clay raw.

SUBSTANCE: the invention is pertaining to production of ceramic materials on the basis of clay raw and may be used, for example, for manufacture of an ordinary and facial building bricks, tiles, lining ceramic tiles, etc. The technical result is improvement of the molding properties of a ceramic mass and so increasing of the raw bricks crack resistance at drying, provision of a capability of a faultless self-acting charging and transportations of the dried semi-product. The method of improvement of molding and drying properties of the clay raw provides for addition of a technological mineral additive representing a rock consisting predominantly from minerals with the developed skeleton- cavernous porosity, drying at the temperature of 200-250°C within 2-4 hours for opening of a porous space, a comminution up to the dimensions less than 1 mm, a uniform distribution along the mass volume with the subsequent souring of the ceramic mass at the temperature of 30-40°C for no less than 24 hours.

EFFECT: the invention ensures improvement of the ceramic mass molding properties, an increase of the raw bricks crack resistance at drying, provision of a capability of a faultless self-acting charging and transportations of the dried semi-product.
