The diagram illustrates the process of bricks manufacturing. The process includes seven stages, beginning with extracting clay from the ground and ending with delivery of packed bricks.
First, the digger is used to extract clay, the raw ingredient, from the ground. Afterwards, the clay is filtered through the metal grid, and the refined clay is moved via a roller. At this point, the water with sand is added to the clay in order to reach the appropriate consistency. The brick itself can be formed either by filling the molds or by using a wire cutter.
After being shaped, the bricks are dried in an oven for 1-2 days. Following this, the bricks are transferred to a kiln, where they undergo two stages of heating: first, at moderate temperatures (200-800 Celsius), and subsequently at high temperatures (870-1300). Once the bricks have passed the kilns, they are then placed in cooling chamber for 2-3 days. Finally, the bricks are considered ready for use and before being delivered, they go through packaging.
