The flowchart describes the way how bricks are made for construction purposes. Overall, the process for manufacturing bricks contains seven main stages, beginning with digging up of clay and ending with delivering stage.
First of all, clay is collected from the ground by using the digger. The clay is then placed on a gird made of metal and cut into smaller pieces by a roller. Before putting it in a mould or using a wire cutter to shape it into brick form, sand and water is added to become a good mixture. Following this, bricks are put in a drying oven during a period of 24 to 48 hours.
In the subsequent stage, the bricks are heated in the kiln under a moderate temperature 200 to 900 Celcius degrees and then a higher up to 1300 Celsius degrees. After that, these experience the cooling process in the chamber for 2 to 3 days. Finally, the bricks are packaged and delivered to the customers.
