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.

First thing

first,

the digger shaped like a truck with two long wheels and a long scope, collects the raw clay materials as the foundation of making the brick.

Then

the clay is placed in the metal grid with square holes, so the small particles of the clay can come down to a roller. The small particles are

then

transported through the roller machine and mixed

together with

sand and water to create a firm substance.

Furthermore

, the firm substance can either be moulded in the 3D rectangle mould or automatically processed by the machine and

then

cut by the wire cutter to produce a brick shape.

Subsequently

, the shaped

bricks

are stacked inside a drying oven for about 24 - 48 hours.

Moreover

, the stacked

bricks

are heated inside a kiln at a moderate temperature of 200 – 980 Celsius degrees,

then

continued in the second kiln at a higher temperature of 870 to 1300 Celsius degrees. In the next step, all the stacked

bricks

are put into the cooling chamber for 48 to 72 hours.

Finally

, all the

bricks

undergo the packaging process and

then

are delivered by a big truck to the customers.
