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

The chart provides data about the manufacturing procedure of

bricks

for the construction industry,describing a series of seven stages from digging clay until delivery.

First,

an excavator collects raw material by digging clay.

Then

, the clay was sorted by a metal grid and sent to a roller. After rolling, water and sand are mixed with the selected material and put in either mould or wire cutter,which is

finally

printed out as

bricks

. After that, a set of

bricks

will be arranged in a drying oven for 24-48 hours.

Next,

all the

bricks

will be moved to a klin at a moderate temperature,standing at 200-980 degrees Celcius and

then

adjusted higher to a high level of 870-1300 degrees Celcius. After heating up, they will be cooled down in a cooling chamber for 48-72 hours as a final process before packing. Before the final step, the

bricks

are packed in a huge tray in order to be ready for delivery which is the

last

stage of brick manufacturing.
