The picture given shows manufacturing process of bricks

The process provides information about moulding of bricks using machines. Overall, manufacturing of bricks requires 7 consecutive steps from excavating to delivery, raw materials required are clay, sand and water. The first step involves the excavation of clay using crane. Then it has to undergo a refining process where clay is seived through a metal grid. During this stage large particles of clay is filtered into finer clay particles. In the following stage, sand and water are mixed to the clay in order to make it mouldable. The next step is moulding the mixture, it can be executed through 2 steps, either by passing the mixture through a machine with wire cutter or placing in a pre-shaped mould. The later step is to dry the moulded bricks as they are moist. Before sending them to baking they need to be dried atleast 1-2 days. Further process involves placing them into kiln 2 times, firstly at a moderate temperature of 200-980 degree C, later upto 1300 degree C maximum. As the product is too hot to handle, it is allowed to cool in a cooling chamber for atleast 2-3 days. Finally the manufactured product is packed and delivered to the consumers.
