Clay Brick Production Line
The main raw material of clay bricks are silty clay or sandy clay, and the main chemical composition are SiO2, Al2O3 and Fe2O3 and crystalline water. Due to the different geological conditions, clay may also contains small amounts of metal oxides of alkali and alkaline earth.
The content of impurities in raw materials clay can bring great impact on the clay bricks calcination temperature and brick color. Clay is the main raw material of clay brick production, but it also can mix with other raw materials such as shale, coal gangue, fly ash, etc. to produce sintered bricks since their chemical composition is similar to clay. But these materials have bad plasticity, so it often need to add a certain amount of clay to meet the plasticity needs of adobe shaping. In addition, coal gangue and fly ash in the adobe brick are combustible industrial waste, containing unburned carbon, which burn inside adobe during sintering, thus saving a lot of firing coal investment. Such bricks also known as internal combustion brick or semi internal combustion brick.
