The provided diagram illustrates the various phases involved in manufacturing bricks for the building industry. We can highlight these phases into seven steps, including digging soil to find the desired material, sorting, mixing, molding, drying, cooling, packaging, and delivering.
Initially, a digger needs to dig the soil surface to find a type of sticky earth, commonly known as clay. At the factory, the clay needs to be segregated from the soil. This process includes the use of machinery such as metal grids and a roller. Chunks of clay then need to be mixed with water and sand, turning them into a homogeneous mixture, which is then molded or cut into brick shapes with the help of a wire cutter.
The bricks then need to be dried in a drying oven for 24 hours at a maximum of 48 hours. They are then transferred into a moderate kiln with a minimum temperature of 200°C and a peak temperature reaching 980°C. Additionally, the bricks need to be kept in a high-temperature kiln (870°C – 1300°C) before being cooled down and hardened in a designated chamber.
Finally, when the bricks are fully hardened, the manufacturer will package them on top of wooden pallets. After being fully packaged, they are ready for delivery in order to distribute them to the building industry.
