The diagram illustrates step-by step process for the making of bricks for building industry. Overall, there are a total of seven stages in the process, beginning from the stage of pure clay and eventually the final stage of ready-to-use industrial bricks.
To begin, the clay is dug out from the ground and spread on the metal grip over the roller. After this step finished, it is subsequently blended with water and sand in the suitable proportion. Afterwards, the moulding could be used in either hand or machine by wire cutter. At this stage, the moulded brick should be firstly dried in a special oven for 24-48 hours.
Next, the dried bricks need to be burnt with moderate temperature of 200*C- 900*C in open kilns to increase the density and hardness. Again, the higher temperature up to 870*C- 1300*C is used to have a good quality of a brick. Eventually, the heated bricks are cooled off for 48- 72 hours. As a final stage, the desirable and qualified bricks are ready for packaging and delivering process.
