The diagram illustrates the process by which bricks are manufactured for use in the construction industry.
Overall, brick production is a linear process consisting of several stages, beginning with the excavation of clay and ending with the delivery of the finished products. The procedure involves preparing and shaping the raw materials, drying the newly formed bricks, heating them at different temperatures, and finally cooling and packaging them for transportation.
Initially, clay is excavated from the ground using a digger before being placed on a metal grid, which filters out larger pieces of debris. The refined material then passes along a conveyor belt, where sand and water are added. Subsequently, the mixture is processed using a roller before being shaped into individual bricks, either by placing it in moulds or by cutting it with a wire cutter.
Once formed, the raw bricks are transferred to a drying oven, where they remain for between 24 and 48 hours. They are then fired in two successive kilns, first at a moderate temperature ranging from 200°C to 980°C and subsequently at a higher temperature of between 870°C and 1,300°C. Following this heat-treatment stage, the bricks are cooled for 48 to 72 hours before being stacked and packaged. In the final stage, the completed bricks are loaded onto trucks and transported to their destination.
