Brick Manufacturing Process

Model answer

The diagram illustrates the multiple processes involved in the production of bricks for industrial purpose. Bricks are made from clay. First, clay is extracted with the help of a digger. It is then placed on a metal grid and then spread on a roller. Afterwards, sand and water are added to the clay. Once the mixture is ready, bricks can be produced in two different ways: the mixture can either be molded or cut into the shape of bricks. In both cases, the bricks are then placed in a drying oven for one to two days. The dried bricks are then heated in a kiln. First, they are heated to a moderate temperature in the range of 200 degree Celsius – 980 degree Celsius. They are then heated again in another kiln to a high temperature in the range of 870 degree Celsius-1300 degree Celsius. The hot bricks are then placed in a cooling chamber for 2-3 days. The cooled bricks are then packaged and transported to construction sites in delivery vans.
