The diagram delineates the step-by-step procedure involved in the production of bricks, which are subsequently utilized in the construction sector.
Overall, the manufacturing process is linear in nature, commencing with the extraction of clay and culminating in the delivery of packaged bricks. Notably, the sole point of divergence occurs during the shaping phase, where two distinct methods are employed.
Turning to the initial stages of preparation and molding, raw clay is first extracted from the earth using a digger. The excavated clay is then conveyed to a metal grid, where it is crushed into smaller fragments by a roller. Subsequently, sand and water are incorporated into the clay, after which the mixture undergoes shaping: it is either cut into precise brick forms using a wire cutter or pressed into a mould to achieve the desired shape.
The ensuing phases encompass thermal treatment and final distribution. Once shaped, the bricks are placed in a drying oven for a period of 24 to 48 hours. Thereafter, they are subjected to firing in two consecutive kilns: initially at a moderate temperature ranging from 200°C to 980°C, followed by a higher temperature range of 870°C to 1300°C. After a cooling period of 48 to 72 hours in a designated chamber, the bricks are packaged and subsequently loaded onto a truck for delivery to their final destination.
