he provided diagram illustrates process of manufacturing bricks from raw materials and further shows how they are processed. Overall, there are 7 main stages, beginning with the clay extraction and ending with the delivery of the final product. Firstly, heavy machinery like diggers are used to extract naturally occurring clay in quarries. Then, extracted materials are filtered through a metal grid to break them into smaller, more even by size particles. Sand and water are later added to form a uniform mixture than can be conveniently cut or moulded. To remove excess water, bricks are put into drying ovens for 1 or 2 days. Then, to enhance hardness and durability of the product, it is transported to industrial kilns, that have various stages of drying. Firstly, to completely dry the product, it is exposed to moderate temperatures of 200-980 degrees. In the next stage, temperatures reach 1300 degrees Celsius, improving structural abilities of clay. Such high temperatures are necessary to reinforce the inner structure of the material. In the last stage of drying, bricks are put into cooling chambers for several days. Finally, product is packaged in boxes and thereafter sent for delivery. Bricks manufacturing is a multi step, technologically advanced process, crucial for any building purposes
