Band 6+: You should spend about 20 minutes on this task. The diagram below shows the process by which bricks are manufactured for the building industry.

The diagram illustrates how the bricks are manufractured for the constructinons industry.

Overall a brief analysis reveals that, this is a stape-by-stape process comprising seven stages and involving various tools and infrastructure. In addition, the process begins with digging clay by a digger and ends with delivering the brcks.

At the first stage of the process clay is dug from the ground using a digger. Then, the clay is passed through a metal grid and is moved onto a roller, where it is mixed with sand and water. After that, the clay can be shaped into bricks in two ways: it is either placed in a mould, or a wire cutter is used.

At the fourth stage of the process, the clay bricks are placed in a drying oven for one to two days. Next, the bricks are heated in a kiln chamber at temperatures ranging from 200’C to 980’C. Then, they are exposed to high temperatures (870’C to 1300’C) before spending two to three days in a cooling chamber. Finally, the finished bricks are packaged and delivered to be sold in the market.
