The flow chart illustrates the production process of bricks usually used in building industry. Generally, seven stages are included, from material exploitation to delivery.
Firstly, underground clay is dug up as the raw material by a large digger. Clay lumps are then stacked on a metal grid which serves to break up chunks into much smaller pieces. After falling on a roller, the stuff is further conveyed and mixed with sand and water.
In following stage, the well-blended compound is pressed in a mould or cut by a wire cutter, in order to form brick-shaped pieces. During next 24-48 hours, dozens of these fresh bricks are kept in a room, namely drying oven.
Once the bricks are dry, the next stage is heating and cooling process. bricks are transferred in a so-called kiln, another type of hotter oven, in which they are burned twice, moderately and highly, in temperature from 200°C-980°C to about 870°C-1300°C. This is followed by depositing heated bricks in a cooling chamber for 2 or 3 days.
Finally, cooled hard bricks get packed and delivered by trucks to their destination, a building site.
