The diagram illustrates the process of making bricks for the building industry.
Overall, it is clear that the process goes through seven steps, beginning with digging up clay and ending in delivery.
As can be seen from the picture, the first step is that the clay is dug up from the ground by a large digger. Before breaking up the clay into smaller pieces on the roller, it is placed on a metal grid. Subsequently, the clay is mixed with sand and water, and this mixture is poured into a mould or a wire cutter to form bricks.
The next step is that after drying in a drying oven for 24-48 hours, they are heated in a kiln at a moderate and high temperature (roughly from 200oC to 1300oC) and cooled in a chamber for 48-72 hours. In the last stage of this process, the bricks are packaged and delivered for building.
