The provided diagram illustrates the various stages involved in the industrial production of bricks for the construction sector. Overall, the process is a linear sequence that transforms raw clay into finished bricks through a series of mechanical, thermal, and cooling treatments, spanning several days.
The initial phase involves extracting clay using a digger, which is then processed through a metal grid and rollers. At this point, sand and water are added to the mixture. The clay is subsequently shaped into bricks using either a wire cutter or a mould. Once formed, these raw bricks are placed in a drying oven for a period of 24 to 48 hours to remove moisture.
Following the drying stage, the bricks undergo a two-stage firing process. They are first heated in a kiln at a moderate temperature ranging from 200°C to 980°C, followed by a high-temperature firing between 870°C and 1300°C. After being fired, the bricks are moved to a cooling chamber for 48 to 72 hours. The final steps of the production cycle involve packaging the cooled bricks and loading them onto a truck for delivery to their destination.
