You should spend about 20 minutes on this task. The diagram below shows how bricks are manufactured. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

The diagram illustrates the brick-making process. The linear process of brick consists of eight main steps from raw material to delivery of

bricks

. 

Overall

, there are two main stages. First

clay

is used to make

bricks

.

Second,

using temperature to harden it.

To begin

with,

bricks

are mainly made from

clay

which is extracted from the earth by machine diggers in large amounts. In the second step metal grid is used to reduce the size of the

clay

by passing it to the roller. In subsequent steps, water and sand are added to solidify the

clay

and

then

the mixture of sand, water and

clay

is put into mould to reshape the

bricks

. In the end, a wire cutter is used to cut them. In the next stage, place the

bricks

in the drying oven for 2 days where three different containers present with different frequencies of temperature. The first two containers have hot temperatures moderate and high, 200-980 degrees and 870-1300 degrees respectively.

However

, the

last

chamber has a cooling temperature where

bricks

can cool down for 2 to 3 days. After hardening packing the

bricks

and ready for delivery.
