The figure illustrates the steps in which bricks are made for the building sector from getting the raw material from the ground to where the end product is delivered.
Firsly, clay is dug up by machines and separated by a metal sheet. The smaller particles fall through to a roller where it is mixed with sand and water. Subsequently, the mixture is either shaped into bricks or send through a passage where it is cut into the correct size with a wire cutter.
The next step of the process is drying the bricks in an oven for twenty-four to forty-eight hours followed by a furnace treatment. In this step, product is exposed to moderate heat (200’C to 980 deg C) followed by high temperature expose of 870 deg C to 1300 deg C after which it is left for forty-eight to seventy-two hours to cool in a chamber.
The last step involves packing the cooled bricks so that it can be loaded onto truck for delivering to customers.
