The diagram illustrates how bricks are made. Overall, it is a linear process consisting of three main stages: shaping the bricks, drying and cooling, and packing for delivery.
Initially, the clay is excavated by a machine known as a digger. Then, the clay is passed through a metal grid, which breaks it into smaller pieces and removes impurities. Next, the clay is transferred onto a roller and shaped into bricks using two different methods: either with wire cutter or mould.
In the second stage, the shaped bricks are dried in an oven for 24-48 hours. Heating in a kiln with a high scale of temperatures, generally, consists of two steps: moderate, warming with 200-980 degrees Celsius, and high, heating them by 870-1300 degrees Celsius. After those steps, bricks must be cooled over a period of 48 to 72 hours before they can be safely handled, transported, and used in construction.
Finally, the finished bricks are packaged and delivered to construction sites by trucks.
