The diagram illustrates the step-by-step process involved in the manufacturing of bricks using machinery.
Overall, the process requires seven consecutive steps for the production of bricks. Raw materials required for brick
manufacturing are clay, sand and water, which are then processed through several machines at different stages to
make the bricks ready to deliver.
At first stage, the clay used for making the bricks is excavated from the earth using a large digging machine. This
clay has to undergo a refining process through a metal grid; during this stage the lumps of clay are refined to finer
clay particles for the next step. In the following stage, sand and water are added to the clay in order to make it
sturdy and mouldable into proper shape. The consecutive step is moulding, which can be executed through two
different steps, either by putting it into a machine with a wire cutter or through putting the raw material into a
pre-shaped mould. The resulting moulded blocks of bricks are fragile and moist; hence, they must be dried before
send them for baking. It takes around 1-2 days to evaporate the moisture.
Once the raw blocks are dried they are placed in the kiln, firstly at a moderate temperature of 200 – 900 degree C,
later to 1300 degree C maximum. As the resulting product is now too hot to handle it is allowed to cool into a
cooling chamber
