The diagram below shows the process by which bricks are manufactured for the building industry. v.2

The diagram gives information about the manufacturing process of construction bricks. Overall, brick manufacturing requires some controlled stages and complex equipment. To begin with, the clay is collected by a digger machine and then the clay is passed through a metal grid to grind them. The smashed clays are transported to a roller and sand and water are mixed with this. The mixture later either moves through a brick cutter, which shape of bricks, or is placed into a mould in which the shape of a brick is formed. Afterwards, these brick-shaped parts are put into a drying oven and stay there for 24 to 48 hours. Next, they are transferred to the first kiln for heating, whose temperature is moderate, 200 to 980 C. After this, they are heated in the second kiln under the high temperature from 870-1300C. Subsequently, in a cooling chamber, they are cooled for two to three days before they are packaged and delivered to the construction sites. To summarise, the whole process consists of generally seven steps during which the raw material is dried, heated, cooled and packaged.
