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

process

by which

bricks

are made for the building industry.

Overall

, there are seven steps in the

process

, starting with the digging up of

clay

and culminating in delivery. First of all, the

clay

which is made of

bricks

is dug up by a big digger.

This

clay

is

then

placed into a metal grid

that is

used to break the

clay

into many small pieces by a roller. In the subsequent stage, sand and water are added to the

clay

.

This

mixture is placed into a mould as a wire cutter. After that, these

bricks

are put in an oven to dry for 24-48 hours.

Following

this

, the

bricks

go through some

process

. They are heated in a kiln at a moderate and high temperature.

Next,

the cooling

process

happens in a chamber for 48-72 hours.

Finally

, the

bricks

are packed and delivered to their destinations.
