The figure displays the process used by the building industry to manufacture bricks.
Overall, this process has 3 phases: obtaining and shaping the clay, heating the clay using a kiln and delivering the bricks. First, the clay is dug using a digger. After that, it is transferred onto a metal grid, then a roller. Next, sand and water is added to the clay which is shaped into bricks using a wire cutter or mould. It is then placed in a drying oven for up to 48 hours and transferred to a kiln with medium and high heat. The stage that takes the longest is the cooling, where the ceramic will be inside a cooling chamber for up to 72 hours. Finally, the bricks are packaged and delivered using a truck.
In conclusion, making bricks only involves a few raw materials and machines, including clay and sand, a roller, digger, drying oven kiln and cooling chamber. Extracting and preparing the clay takes a relatively short time compared to heating, cooling and drying, where each stage can take around 1-3 days.
