The diagram below shows the process by which bricks are manufactured for the building industry.
The diagram illustrates the process of manufacturing bricks for the building industry, from raw material extraction to final delivery.
Overall, brick production involves several stages, starting with clay excavation and ending with packaging and delivery. The process combines mechanical and thermal steps to ensure high-quality bricks.
The process begins with clay being excavated and filtered through a metal grid before being crushed by rollers. Sand and water are added to the clay, and the mixture is shaped into bricks using either molds or a wire cutter. The shaped bricks are then dried in an oven for 24–48 hours.
Following drying, the bricks are heated in kilns at moderate temperatures (200–980°C) and then at higher temperatures (870–1300°C). They are cooled in a chamber for 48–72 hours before being packaged and delivered to customers.
