The flowchart portrays consecutive stages of how construction bricks are produced.

Overall, it is obvious that there are seven steps in the bricks procedure, beginning with collecting fresh clay and ending with transporting the end products to the market. Two main ingredients are required in brick production.

As is presented in the flow diagram, it is obvious that natural clay, which is below the ground, is dug out of the ground by a digger machine. After that, this clay is placed onto a metal grid and is filtered and processed by a roller into small chunks. This smashed clay is then mixed with sand and water, and then, this mixture is either put in a mould or put through a die which is then cut by a wire cutter to form column bricks of the same size.

In the next stage of bricks production, we can also see that the brick-shaped is put in a drying oven for one or two days. After that, these dried bricks are heated in a kiln at a moderate temperature (200 – 980 degree Celsius) before placing them in a kiln at a higher temperature up to 1300C. Consequently, bricks are cooled in a cooling chamber for two or three days, before being packaged and delivered to construction sites for building purposes.
