The diagram illustrates the step-by-step process of brick manufacturing for the construction industry. Overall, the production involves seven key stages, beginning with raw material extraction and culminating in delivery, with temperature-controlled phases playing a big role.
The process starts by a digger extracting clay from the ground, which serves as the primary raw material. Next, the clay is shaped into bricks using either a wire cutter or a mould. Following this, the molded bricks are dried in an oven for 24 to 48 hours to remove moisture.
Subsequently, the bricks undergo two heating phases in a kiln. First, they are exposed to moderate temperatures ranging from 200°C to 980°C. Then, they are fired at high temperatures between 870°C and 1300°C to strengthen them. After heating, the bricks are transferred to a cooling chamber to stabilize their structure.
Finally, the finished bricks are packaged and delivered to construction sites for use in brickwork. Notably, the entire process relies on precise temperature control to ensure durability.
In summary, brick manufacturing is a linear yet temperature-sensitive process that transforms clay into construction-ready materials through shaping, drying, firing, and cooling.
