The diagram illustrates the stages in the production of bricks for the construction industry.
Overall, it can be seen that the process consists of nine steps, starting by digging and ending by delivering.
At the first stage in the production of bricks, clay is dug by a digger. Secondly, it goes through a metal grid and passes onto a roller, where sand and water are added. Next, the clay can be shaped either by a wire cutter or a mould. After giving it a shape, clay bricks are put into a drying oven, where they dry for 24 to 48hours.
Afterwards, they are put into kiln, where they are firstly heated in a moderate temperature, between
200C and 980C, after which they are again heated, but in a high temperature, 870C to 1300C. At the seventh step, bricks are cooled in a cooling chamber for 2 to 3days. After being cooled, the bricks are packeged and they are finally ready to be delivered in a lorry to building industries.
