The diagram represents the step-by-step process of producing bricks for the building industry.
Overall, the process can be divided into three primary stages, starting from digging the clay, followed by the hardening process, and ending with delivering to the construction sites. Notably, the process involves several machines and limited amount of human involvement.
In the initial phase of the entire process, clay is dug using digger before passing through a metal grid and placing it on the roller. Following this, water and sand are mixed with the clay. The prepared clay mixture is used to form bricks with the help of the wire cutter method or the mold method. In the wire cutter method, the mixture is shaped into a continuous slab and then cut into individual bricks by a wire cutter machine. In the mold method, the clay mixture is pressed into molds to form bricks.
After being formed, bricks are placed in a drying oven for 24 to 48 hours to get rid of excess moisture. After the drying process, the bricks are moved to a kiln for firing, which has two stages, moderate heating and high heating. In the moderate heating, bricks are fired at moderate temperatures ranging from 200 degrees to 980 degrees. In the high heating, temperature is increased to high levels between 870 degrees and 1300 degrees. To set the fired bricks, they are placed into a cooling chamber and kept there for 48 to 72 hours. The finished bricks are packaged and distributed for use in the building industry.
