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.

Sample Answer 1:

The given diagram shows different stages of brick manufacturing for the building industries. Generally speaking, brick production involves 7 steps, starting from the digging stages and ending at the delivery stage.

As is given in the graph, the first step of brick manufacturing is digging the clay with a large digger. This clay is then filtered and processed in a roller machine and then mixed with sand and water. In the third stage, the mixture is either kept in a mould or cut in a wire cutter to make the raw shape of the bricks. In the next step, the shaped raw bricks are dried for 24 to 48 hours in a drying oven. After that, the dried raw bricks are kept in a kiln, both in moderate and high temperature, up to 1300 degree centigrade and then placed in a cooling chamber for about 48 to 72 hours. This process makes the brick to be packed and delivered in the final two steps. The delivery process is the final process of brick manufacturing and as it is noted, brick making is a moderately complex process that requires some predefined works to make it usable.

Model Answer 2:

The diagram gives information about the manufacturing process of construction bricks. Overall, brick manufacturing requires some controlled stages and complex equipment.

To begin with, the clay is collected by a digger machine and then the clay is passed through a metal grid to grind them. The smashed clays are transported to a roller and sand and water are mixed with this. The mixture later either moves through a brick cutter, which shape of bricks, or is placed into a mould in which the shape of a brick is formed. Afterwards, these brick-shaped parts are put into a drying oven and stay there for 24 to 48 hours. Next, they are transferred to the first kiln for heating, whose temperature is moderate, 200 to 980 C. After this, they are heated in the second kiln under the high temperature from 870-1300C. Subsequently, in a cooling chamber, they are cooled for two to three days before they are packaged and delivered to the construction sites.

To summarise, the whole process consists of generally seven steps during which the raw material is dried, heated, cooled and packaged.
