The diagram illustrates the process that is used to manufacture bricks for the building industry.
Summarize the information by selecting and reporting the main features and make comparisons where relevant.
The diagram shows the process by which bricks are built from clay for building industry.
Firstly, clay as the main component of brick is dug from the ground using heavy machinery, in the form of big granules, which is then sorted out over a metal grid and a conveyer belt. After that, before it is poured into rectangular moulds to form raw bricks, it is mixed with sand and water.
Secondly, raw bricks that are made one by one into moulds or into large pieces separated by wire cutters are moved to drying oven, in which are kept for a day or two to become dry and hard. Next steps happen in hot cooking chambers called klins, where dried bricks are heated to moderate(870-1300 Celcius) and high (200-980 Celcuis) temperatures and then kept in cooling chambers for about 2 to 3 days. The, the final bricks are delivered by trucks.
Overall, the process of manufacturing bricks is a simple one which involves only a few short steps and requires low technology(171 Words).
