The diagram below shows the process by which bricks are manufactured for the building industry. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram depicts the production process of

bricks

before being used as building materials in the construction sector.

Overall

, there are four key stages in order to transform

clay

into

bricks

, commencing with

clay

digging, followed by brick shaping,

then

heating treatment, and

finally

packaging and delivery. In the initial stage of brick production,

clay

as the primary raw material, is excavated using a digger.

Subsequently

, the extracted

clay

undergoes a sorting process through a metal grid before passing through a roller.

After

this

, the resulting material is blended with sand and water to shape it into the desired dimensions.

This

shaping process can employ either a wire cutter or moulds to create the individual

bricks

. In the subsequent stage, heat is applied to those

bricks

.

Initially

,

bricks

are dried in a drying oven between 24 and 48 hours. After that, it will be transferred into a kiln which has moderate temperatures ranging from 200 to 900 degrees Celsius, and high temperatures, reaching 870 to 1300 degrees Celsius. Afterwards, the

bricks

enter a cooling chamber for a duration of 48 to 72 hours.

Finally

, the

bricks

undergo packaging before being delivered to customers.
