Sample Answer

The process of manufacturing bricks for the construction industry can be outlined in seven consecutive steps.

First the raw material, clay, which lays just below the surface of soil in certain clay-rich areas has to be dug up by a digger.

Then the lumps of clay are placed on a metal grid in order to break up the big chunks of clay into much smaller particles, which fall through the metal grid onto a roller, whose motion further segregates the bits of clay. Sand and water are added to make a homogenous mixture, which is then either formed in moulds or cut into brick-shaped pieces by means of a wire cutter.

Those fresh bricks are then placed in a drying oven for at least 24 and a maximum of 48 hours, several dozen if not hundreds of bricks at a time. The dried bricks are then transferred to the so-called kiln, which is just another type of high temperature oven. First the bricks are kept there at a moderate temperature of 200C – 1300C. This process is followed by cooling down the completed bricks for 48 to 72 hours in a cooling chamber.

Once the bricks have cooled down and have become hard, they get packaged and delivered to their final destination, for example, a building site or a storage.
