The process diagram shows how bricks are made from clay for the construction industry
Overall, the brick-making process involves 7 steps, beginning with the extraction of raw material from the ground and finishing with the delivery of the finished bricks.
First of all, clay is dug from the ground with a digger and then put through a metal grid which sifts the large chunks from the pure clay. Sand and water is then added and the mixture is either cut into bricks with wire or put into a rectangular mould to achieve the final shape.
Once the bricks have been formed, they are sent to a drying oven for 1 to 2 days before entering the heating stage. Here, they are heated in kilns firstly at moderate temperatures (200-980 degrees Celsius) and then at high temperatures (up to 1300 degrees). The cooked bricks are then moved into a cooling chamber for another 48-72 hours. From here, they are packaged and transported to their final destination by truck.
