The diagram outlines the process of manufacturing bricks for the infrastructural purposes. The entire process involves several stages, starting from the extraction of raw clay materials, then shaping and drying the bricks, followed by firing and cooling, and finally packaging and delivery.
To commence with the process, clay is excavated from its ore using a digger. The feed is then sifted with a metal grid to obtain the required fine size while filtering out any large debris. To form a consistent mixture for the further extrusion, the sieved clay is mixed with sand and water before brick-shaping is done using a wire cutter or molding to obtain the desired shape and size.
These newly formed bricks are then transferred to a drying oven, where they are left to dry for 24 to 48 hours. After drying, for the firing process in the kiln, the bricks undergo two stages: the first stage involves heating them to a moderate temperature of 200°C to 980°C, while the second involves heating them to a higher temperature of 870°C to 1300°C. Following the firing process, they are cooled in a cooling chamber for 48 to 72 hours. Once cooled, the final step is implemented with the packaging and preparation for delivery to various construction sites.
