The diagram presents the procedure of brick production for construction purposes.
Overall, it is a linear process consisting of seven main stages: digging, screening, crushing, mixing, shaping, drying, and finally packaging and delivery.
The process begins with the extraction of clay from the ground using an industrial digger. Next, the clay is placed on a metal grid, where large particles are sifted out and the remaining material is crushed by a roller. Water and sand are then added to the crushed clay to form a mixture, which is poured into rectangular moulds. Alternatively, the mixture can be shaped into bricks using a wire cutter.
The shaped bricks are placed in a drying oven, where they remain for approximately 24 to 48 hours. Next, the dried bricks are heated in two kilns. The first kiln operates at a moderate temperature of 200 to 980°C, while the second reaches a high temperature of 870 to 1300°C. After heating, the bricks are cooled in a cooling chamber for 48 to 72 hours. Subsequently, the bricks are packaged. Finally, the packaged bricks are loaded onto a truck and delivered to their destination.
