The diagram illustrates the process of brick production. Overall, it is a linear process consisting of three main stages: shaping the bricks, drying and firing, and packaging for delivery.
Initially, clay is excavated by a machine known as a digger. The raw material is then passed through a metal grid, which breaks it into smaller pieces and removes impurities. After that, the clay is transferred onto a roller and shaped into bricks either by using a wire cutter or by placing it into moulds.
In the next stage, the newly formed bricks are dried in an oven for a period of 24 to 48 hours. They are then fired in a kiln in two phases, beginning with moderate temperatures of between 200 and 980 degrees Celsius, followed by a higher heating stage ranging from 870 to 1300 degrees Celsius. Once firing is complete, the bricks are cooled in a cooling chamber for 48 to 72 hours.
Finally, the finished bricks are packaged and delivered to construction sites by truck.
