The diagram illustrates the process involved in manufacturing bricks for the construction industry. Overall, the procedure consists of several key stages, beginning with the extraction of clay and ending with the packaging and delivery of the finished bricks. Each step plays a vital role in ensuring the bricks are durable and suitable for building purposes.
Initially, clay is dug out using a mechanical digger and is then crushed by being passed through a metal grid and roller to produce fine clay particles. After that, sand and water are added to the clay, and the mixture is shaped into bricks. This shaping can be done either by using a mould or by cutting the mixture with a wire cutter.
Once the bricks are formed, they are placed in a drying oven for 24 to 48 hours to eliminate excess moisture. They are then transferred to a kiln, where they are first heated at a moderate temperature (200–980°C) and then at a higher temperature ranging from 870 to 1,300°C. Following the heating stage, the bricks are cooled in a cooling chamber for 48 to 72 hours.
In the final stage, the cooled bricks are packaged and prepared for delivery to various construction sites.
