The diagram illustrates the process of manufacturing construction bricks. Overall, burnt bricks are created by seven main steps, beginning with collection of raw materials and ending with the step of transporting products to the stores.
The first stage in the process is collection of unprocessed materials which are known as clay and are collected by digger. Subsequent step, this clay is filtered by the metal grid and roller to choose the materials suitable for processing. After that, they are mixed with sand plus water, then place it into the mould or wire cutter to make bricks.
At the following stage, bricks are placed in a drying oven for 24-48 hours. The next step is burning. Bricks are placed in a kiln, beginning with 200*C-980*C, then people burn them with 870*C-1300*C. After this step, these burnt bricks are refrigerated by cooling chamber for 2-3 days. When the burnt bricks have been fired, they are packaged. Final step is transporting products to the stores.
