An Overview Of Brick Manufacturing Process

Posted by Admin on July, 29, 2014

Bricks are an indispensable part of most construction projects, be it small or large scale. Bricks are used by the human beings since centuries and are seen as one of the oldest and durable forms of construction materials. Bricks are hardened masses of clay, aggregate, cement and water shaped into mold and hardened by drying and firing. In the earlier times, the clay was dug and the bricks were made and set into kilns manually. But, presently, they are made using technologically advanced machines for manufacturing bricks. Let us look at the Brick Manufacturing Process in detail below:

Brick Manufacturing Process

There are several processes involved in the manufacturing of bricks. These processes are explained below:

  • Winning- in order to extract clay and shales, heavy earth-moving equipment are used such as scrapers, mechanical shovels and bull dozers.
  • Crushing and blending- the materials are transported from the pit with the help of trucks or endless conveyors. All the materials are then stockpiled in order to blend the various types of clays.
  • Grinding- the mixed clay is carried away by conveyors for secondary crushing. The secondary grinding is done in the pan mill equipped with two heavy steel wheels. The wheels lying on the axle are connected to a central vertical spindle. The wheels rotate around the spindle and crush the clay against the pan base.
  • Screening- the clay is screened to check for oversized pieces before being shaped. The oversized pieces are returned to the pan mill for crushing.
  • Shaping – the bricks are hand formed, extruded and pressed into their final shape. The final appearance and texture of the bricks depend upon the method used for shaping.
  • Extruding- the clay is forced into a horizontal cone shaped tube by an auger moving down the die. During the process, two compaction stages are involved.
  • Drying- the moisture content from the brick must be reduced before they are fired. This is done with the help of tunnel driers and chamber driers.
  • Firing – bricks are fired at temperature of about 1000 to 1200 degrees Celsius. The bricks are backed in the fire kilns.
