The diagram illustrates the step-by-step process of manufacturing bricks for the construction industry.
Overall, the linear production pipeline consists of seven main stages, beginning with the extraction of raw clay from the ground and culminating in the delivery of the finished packaged bricks to suppliers.
In the initial stage, clay is excavated using a heavy digger. This raw material is then placed onto a metal grid and processed through rollers to break it down into smaller, finer pieces. Following this, sand and water are mixed with the clay. The resulting mixture is subsequently shaped into individual bricks, either by being extruded and cut with a wire cutter or pressed directly into moulds. Once shaped, the raw bricks are transferred to a specialized oven to dry for 24 to 48 hours in order to remove excess moisture.
After being dried, the bricks undergo a rigorous two-step firing process inside kilns. They are first subjected to moderate heat, ranging from 200°C to 980°C, before moving into a high-temperature kiln set between 870°C and 1300°C. Next, the heat-treated bricks are placed into a cooling chamber for 48 to 72 hours. Finally, the completed bricks are packaged onto pallets and loaded onto trucks for transport and delivery.
