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

The diagram provides information about how brick is produced.

Overall

, the process comprises a number of stages, starting with excavating clay, through different mixing steps, and ending with the final products being distributed. At the beginning of the process, clays are dug by an excavator, after which they are sifted by a grid to distinguish metal and sand in order to obtain pure sand.

Subsequently

, these pure sand are mixed with an amount of appropriate water to ensure that the mixture is not too thick or liquid. After that,

this

blend is cut by a wire cutter or moulded in mould to form the bricks. The process continues with bricks being arranged and dried in a drying oven for about 1-2 days, before being transported to a big tank which is divided into three cavities. After experiencing medium and high temperatures respectively, bricks are cooled in a cooling chamber for about 2-3 days.

Finally

, the final products are packed and transmitted to retailers by trucks.
