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 diagram describes the process by which

bricks

are manufactured and used in the building industry.

Overall

there are seven processes in the production of

bricks

starting with the digging of

clay

and ending with the delivery of

bricks

.

Initially

, the

clay

, which is used as a raw material for the production of

bricks

, is excavated by a huge digger from the ground and

then

transferred by lorry to a factory in Homeland. In the next stage, the

clay

is placed on a metal grid to separate oversized particles from smaller ones, and

subsequently

, small particles of

clay

are poured from a metal grid onto the surface of a large roller before mixing with sand and water.

Next,

the mixture is moulded or cut with the help of a wire cutter to form raw

bricks

.

In addition

, raw

bricks

are placed in a drying oven for about 24–48 hours, during which the water is evaporated.

Further

dried

bricks

are heated in two kilns twice at a moderate temperature (200–980 °C) and at a high temperature (830–1300 °C), respectively. In the final stage, the dried

bricks

are transferred into a cooling chamber, where they are cooled for 2–3 days.

Finally

, the manufactured

bricks

are packed and distributed to the market in Someland for the purpose of construction.
