Basic Brick Properties Clay Bricks are made of Silica, Alumina, Lime,
Iron, Manganese, Sulfur, and Phosphates. They are poor conductors and are non combustible.
Young’s modulus = 1.5 x 106 psi – 5.0 x 106 psi Modulus of Rupture = 500 – 3800 psi Density = 125 pcf Common uses include building, facing, flooring,
and paving.

Mining and Storage 3 Types of Clay are used to make Brick Surface Clays – sedimentary formations found on the
surface Shales – clays subject to high pressures until nearly
hardened into slate Fire Clays – mined at deeper levels than other clays Mined in open pits then transported to plant storage
areas

Size Reduction Dry Pan Crushers- Breaks large chunks of
clay or shale Grinders- pulverizes the clay to a fine
consistency (Muller Wheels) Important to have clays dry when grinding

Screening
Passes through Vibrating Screen, Scalping Screen
Coarse material left goes back to grinder Hammer mill Large particles inhibit the durability of the
brick

Forming Two steps in the forming process Tempering
Water is added to the clay in a pug mill Molding
Stiff Mud Soft Mud Dry-Press

Drying The moisture content of the formed clay is
reduced, not eliminated, so that the brick will not explode during the firing process.
The clay is sent through a drying chamber for 24 to 48 hours at 100 to 400 deg F.
Heat and humidity must be regulated to avoid cracking in the brick

Firing
Tunnel Kiln – Most Common, four stages
Final Drying and Dehydration: 300° F - 1800° F
Oxidation: 1000° F - 1800° F Vitrification: 1600° F - 2400° F Flashing: Varies depending on
desired color

Cooling and Processing Tunnel Kiln-10 hours Rate of Cooling has direct effect on color Dehacking
Unloading a kiln after cooling Bricks are sorted ,
graded, then packaged.
