The diagram depicted elaborates the
brick manufacturing process which is carried out in 7 phases.
The process starts with digging up of clay from the ground. The lumps of clay are
placed on a metal grid in order to pulverize big pieces into smaller which in
turn are carried to another chamber with help of roller where the lumps are
mixed with sand and water. The homogenized solution is then is molded into raw
wet bricks with help of a wire cutter or a mould.
The freshly formed brick pieces at taken to a
drying over and left for drying for 24 to 48 hours. After the brick pieced have
dried, they are transferred to the kiln chamber, where they are baked in 2
chambers. The first chamber heats bricks at moderate temperatures, i.e. between
200C-980C and second bakes between 870C-1300C.
After baking process, bricks are
cooled in a cooling chamber of 72 hours. Then the bricks
are packaged and delivered on final destination.
