The provided process diagram intricately outlines the multifaceted steps the building industry undertakes in order to produce bricks.
The overall process comprises three stages; the initial procurement of raw materials, the actual production phase, and finally, packing and delivering the end product.
The entire process is initiated with the excavation of clay using a digger. A metal grid filters the clay, and a roller moves the fine clay for mixing, where the clay is blended with sand and water. Bricks are made at this stage through the utilisation of either a wire cutter or a mould. The bricks are then sent to an oven for drying.
After 24 to 48 hours of baking in the drying oven, the bricks undergo further processing in a kiln; first, at temperatures ranging from 200 to 980 degrees Celsius followed by high temperatures ranging from 870 to 1300 degrees Celsius. Once the baking is finished, the bricks are cooled down in a chamber for 2 to 3 days. After cooling, the bricks are packed and delivered in a truck.
