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

The chart explains the way in which

bricks

are made for the building industry.

Overall

, the action of producing the

bricks

involves 5 main stages starting from digging up of the

clay

and ending with the delivery of goods ready to use.

To begin

, the

clay

used to make the

bricks

is dug up from the ground by a large digger.

This

clay

is

then

placed onto a metal grid, which is used to break up the

clay

into small pieces. A roller assists in

this

operation as well.

Following

this

, sand and water are added to the

clay

, and the mixture is turned into

bricks

by either placing it into a mould or using a wire cutter.

Next,

after receiving the

bricks

, they are placed in an oven to dry for 24-48 hours. In the subsequent stage, the

bricks

go through a heating and cooling step. They are heated in a kiln at a moderate and

then

a high temperature (ranging from 200 C to 1300 C), followed by a cooling procedure in a chamber for 2-3 days.

Finally

, the

bricks

are ready for package and delivery to their destinations.
