The diagram shows how bricks are produced for building industry. Overall, there are three main stages in the production of bricks; starting with processing raw materials, followed by making half-ready bricks, and lastly preparing fired bricks for selling. Additionally, the brick production process is complex, requiring much time and equipment to complete. In the first stage of brick manufacturing, clay are dug by excavator, then the clay go through metal grid on rollers before water and sand being added. Later, there are two ways to produce brick; using wire cutter and mould. The half ready bricks are put inside the drying oven for 24 to 48 hours, followed by being kept in kiln; at moderate temperatures from 200oC to 980oC and then at high temperatures from 870oC to 1300oC. 48-72 hours are required for heated bricks to be cooled down in the chamber. Next, the bricks are prepared and packaged to be delivered for customers
The diagram shows how bricks are produced for building industry.
Overall, there are three main stages in the production of bricks; starting with processing raw materials, followed by making half-ready bricks, and lastly preparing fired bricks for selling. Additionally, the brick production process is complex, requiring much time and equipment to complete.
The process begins when clay are dug by excavator after which the clay is gone through metal grid where the clay is sorted into big and small particles. In the following step, fine clay is moved to the next step in which water and sand are added to brought clay to form mixture. The mixture, then, is turned into brick shape in two different ways ; either the mixture is gone through a frame and cut into bricks or it is put into mould to form bricks.
Afterwards, The half ready bricks are put inside the drying oven for 24 to 48 hours, before being kept in kiln; at moderate temperatures from 200oC to 980oC and followed by high temperatures from 870oC to 1300oC, which is followed by a cooling process for 48-72 hours in the chamber. The process ends with cooled bricks being packaged before being delivered.
