The diagram illustrates the process of brick manufacturing, showing how bricks are produced from raw materials and prepared for delivery.
Overall, brick production consists of seven main stages starts with digging clay and ends with packaging and delivery. During this process, bricks are shaped, dried, heated at different temperatures, and then cooled before being sent to customers.
First, clay is dug from the ground by a digger. Then it is passed through a metal grid, which breaks the clay into smaller pieces. After that, sand and water are added to the clay, and the mixture is rolled to make it smooth. The clay mixture is then shaped into bricks either by using a mould or by a wire cutter.
Next, the bricks are placed in a drying oven for 24 to 48 hours. After being dried, they are heated in a kiln. First, they are baked at a moderate temperature of 200-980°C, and then at a higher temperature between 870 and 1300°C. Finally, the bricks are cooled for 48 to 72 hours. Following this, it is packaged, before being delivered.
