The diagram illustrates the steps involved in manufacture of bricks by the building industries, providing the overview of a procedure from digging the land for clay till the packaging and delivery of the formed bricks in a series of 7 steps.
The digger machine is used to extract clay of suitable consistency from the excavation site. This raw clay is then sent to the manufacturing unit for further processing. The next step is to transfer the raw clay obtained by the digger onto a metal grid, which further is sent to a roller as small pieces. Clay is mixed with sand and water, and the formed mixture is then passed and with the help of wire cutter. The bricks of required dimensions are formed with this step. The mixture of clay, sand and water can also be transferred into a mould to form another variation of bricks.
The Newly cut bricks are then placed in a drying oven for solidification. The drying process is done for 24-48 hours. The solid brick is then placed inside high temperature kilns. These kilns expose the brick to varied temperature ranging from a moderate 200-980 C to a high 870-1300 C. the bricks are then passed in a colling chamber. The colling process can last from 48 and can happen for as long as 72 hours as well.
After adequate cooling of the bricks is achieved, they are sent for packaging. The packaged bricks are further processed for shipping and delivery to the companies.
