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 illustrates the steps involved in the manufacturing of

bricks

for the building industry.

Overall

, the process begins by digging out

clay

from the ground, which is

then

processed, put into moulds, and

then

passed through various chambers. It is

finally

packaged and sent out for delivery.

Bricks

are made of a special type of sticky soil called

clay

, which is dug out by a digger.

Firstly

, the

clay

is passed through a metal grid onto a roller.

Secondly

, sand and water are added to the

clay

, which is

then

cut into brick-like cuboids, which are

finally

put into moulds to get the desired shape. The raw

bricks

are

then

put in a drying oven for 24 to 48 hours. They are

further

transferred to another chamber which has three compartments, two of which are kilns, the first has a moderate temperature ranging between 200 to 980 degrees Celsius,

while

the second maintains a high temperature between 870 to 1300 degrees Celsius, and the third compartment is the cooling chamber. After being baked in the kilns, they are cooled for 48-72 hours.

Finally

, the

bricks

are ready for packaging and are delivered to their requested sites. In conclusion, making

bricks

is a long process, and it takes a few days to make the final product from soil.
