The given diagram illustrates the process of making bricks. There are seven stages involved in the brick production, starting with the clay being collected and ending with the product delivery.
At the beginning of the process, clay is dug out of the ground by diggers. The clay collected is then filtered through metal grids down to rollers which are placed right beneath. After that, the clay is mixed with sand and water. the mixture can be either put in wire cutters or shaped in the moulds to form bricks.
The process continues with the bricks being dried in drying oven for one or two days. Subsequently, the bricks are heated in two different kilns at different temperatures, firstly at moderate temperature (200 C – 980C) and then at high temperature (870C – 1300 C) before being cooled down in cooling chambers for two or three days. At the following stages, the bricks are ready to be packaged and delivered by trucks.
