The diagram illustrates the production of bricks for building purposes.
Overall, the process consists of seven distinct stages which can be divided into two sets: shaping bricks and treating them under certain temperatures. Various pieces of machinery are required for this process, including digging, drying and cooling equipment. In terms of materials, clay, sand and water are among the key ingredients.
The manufacture cycle begins with the process of digging clay by means of bulldozing machinery. The clay is then transported to a factory where it passes through a metal grid and is placed on the roller. Subsequently, the material is mixed with sand and water to produce a substance that can either be split into pieces by a wire cutter or be placed into moulds to produce bricks.
From this point, the resulting bricks proceed into a drying oven to be kept there for 24-48 hours. The following production stage involves heating the bricks in kiln at moderate temperatures up to 980o C and then at higher ones between 870o C and 1300o C. The hot bricks are later placed in a cooling chamber for 48 to 72 hours before being packed and ready for delivery to customers.
