The diagram illustrates the process that is used to manufacture bricks for the building industry. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The flowchart shows how

bricks

are produced for construction purposes.

Overall

,

it is clear that

the entire process of making

bricks

consists of eight steps, beginning with the collection of clay and concluding with the delivery of the finished product to the market. In the first stage, clay is collected by a digger; after which the collected materials are sieved using a metal grid. The sieved clay is

then

transported on a roller to mix with sand and water, resulting in a mixture for

further

processing. In the following stage, the mixture is cut by a wire cutter or moulded into raw

bricks

before being moved into a drying oven to dry for 24 to 28 hours. Once the raw

bricks

are dried, they are transported to a kiln where they are

initially

heated at moderate temperatures (200 °C to 980 °C) and

then

further

heated at higher temperatures ranging from 870 °C to 1300 °C.

Subsequently

, the heated

bricks

are transferred to a cooling chamber for 48 to 72 hours. In the

last

step, the finished products are packaged to be delivered by truck to construction sites that use the

bricks

.
