The diagram illustrates the process of brick manufacturing for the building industry. Overall, there are seven stages in this process, beginning with the excavation of clay and concluding with the delivery of finished bricks.
The first step involves digging clay with large machinery. The excavated clay is then filtered and mixed with sand and water. In the third stage, the mixture is either molded or cut using a wire cutter to form the bricks.
Next, the bricks are dried for 24 to 48 hours in a drying oven. After drying, they are placed in a kiln, where they are subjected to moderate and high temperatures (up to 1300 degrees Celsius) and then left to cool for about 48 to 72 hours inside the kiln.
Finally, the bricks are packaged and prepared for delivery. Once this process is complete, the bricks are ready for use in the building industry.
