Bricks are the only man-made building materials that testify to their use since the early human civilization. With their attractive appearances and superior properties such as high compressible strength and durability, excellent fire and weather resistance, good thermal and sound insulation, bricks are widely used for building, civil engineering work, and landscape design. |
| Automatic unfired brick stacking machine |
Bricks for building may be made from clay, shale, soft
slate, calcium silicate, concrete, or shaped from quarried stone. However, true
bricks are ceramic, and therefore created by the action of heat and cooling.
Clay is the most common material, with modern clay bricks formed in one of
three processes - soft mud, dry press, or extruded.

Clay Brick Producing Technical Process:
Most brickworks have some or all of the following:
- A kiln, for firing, or 'burning' the bricks.
- Drying yard or shed, for drying bricks before firing.
- A building or buildings for manufacturing the bricks.
- A quarry for clay.
- A pugmill or clay preparation plant

In a typical modern brickworks, clay is taken from the quarry, and then carried by conveyor belt or truck/lorry to the main factory, although it may be stockpiled outside before entering the machinery. When the clay enters the preparation plant (Clay Prep) it is crushed, and mixed with water and other additives which may include breeze, a very fine anthracite that aids firing. This process, which is also known as pugmilling, improves the consistency, firing qualities, texture, and color of the brick. From here, the processed clay can be extruded into a continuous strip and cut with wires, or put into moulds or presses (also referred to as forming) to form the clay into its final shape. After the forming or cutting, the bricks must be dried, either in the open air, in drying sheds, or in special drying kilns. When the bricks have been dried, they must then be fired or 'burnt' in a kiln, to give them their final hardness and appearance. |

Double Shaft Mixer efficiently mix dry to very wet
materials, or blend liquids and sludges with dry solids. Materials can range
from wet and sticky clays, sludges, or filter cakes to silty, sandy soils and
other abrasives. These machines can be used as pugmills for mixing liquids or
sludges with dry solids, especially when a greater tub volume is required for
longer retention times. Most often, they are used for the intensive blending of
two dissimilar wet or dry materials.

6. Brick extruder
 |
| Brick extruder |
For extruded bricks the clay is mixed with 10-15% water
(stiff extrusion) or 20-25% water (soft extrusion). This is forced through a die to
create a long cable of material of the proper width and depth. This is then cut
into bricks of the desired length by a wall of wires. Most structural bricks
are made by this method, as it produces hard, dense bricks, and suitable dies
can produce holes or other perforations. The introduction of holes reduces the
volume of clay needed, and hence the cost. Hollow bricks are lighter and easier
to handle, and have thermal properties different from solid bricks. The cut
bricks are hardened by drying for 20 to 40 hours at 50 to 150 °C before being
fired. The heat for drying is often waste heat from the kiln.
Vacuum extruder, double stage, hard plastic
Vacuum extruder of hard plastic are mainly used to produce
bricks with low plastic materials as raw materials, such as coal gangue, fly
ash, shale, sandy soil of poor quality, etc., and produced bricks strength can
reach 3.5-4 KG/cm2.

10.Hoffman kiln
The Hoffmann kiln is a series of batch process kilns.
Hoffmann kilns are the most common kiln used in production of bricks and
some other ceramic products. Patented by German Friedrich
Hoffmann for brickmaking in 1858, it was later used for lime-burning, and
was known as the Hoffmann continuous kiln.
A Hoffmann kiln consists of a main fire passage surrounded
on each side by several small rooms. Each room contains a pallet of bricks. In
the main fire passage there is a fire wagon, that holds a fire that burns
continuously. Each room is fired for a specific time, until the bricks are vitrified properly,
and thereafter the fire wagon is rolled to the next room to be fired.
 |
| Hoffman Kiln & Dryer Layout |
Each room is connected to the next room by a passageway
carrying hot gases from the fire. In this way, the hottest gases are directed
into the room that is currently being fired. Then the gases pass into the
adjacent room that is scheduled to be fired next. There the gases preheat the
brick. As the gases pass through the kiln circuit, they gradually cool as they
transfer heat to the brick as it is preheated and dried. This is essentially a counter-current
heat exchanger, which makes for a very efficient use of heat and fuel. This
efficiency is a principal advantage of the Hoffmann kiln, and is one of the
reasons for its original development and continued use throughout history. In
addition to the inner opening to the fire passage, each room also has an outside
door, through which recently-fired brick is removed, and replaced with wet
brick to be dried and then fired in the next firing cycle.
In a classic Hoffmann kiln, the fire may burn continuously
for years, even decades. Any fuel may be used in a Hoffmann kilns, including gasoline, natural
gas, heavy petroleum and wood fuel. The dimensions of a typical Hoffmann
kiln are completely variable, but in average about 4 m (height) x 15 m (width)
x 150 m (length).
Tunnel kiln
In modern brickworks, clay bricks are usually fired in
a continuously fired tunnel kiln, in which the bricks move slowly through
the kiln on conveyors, rails, or kiln cars to achieve consistency for all
bricks.
Tunnel kiln is a long structure in which only the central
portion is directly heated. From the cool entrance, ware is slowly transported
through the kiln, and its temperature is increased steadily as it approaches
the central, hottest part of the kiln. From there, its transportation continues
and the temperature is reduced until it exits the kiln at near room
temperature.
The tunnel kiln is composed of of furnace body, traction
system, rail, kiln-car, and firing system, hot air ventilation system, control
system, etc. The design and manufacture of the tunnel kiln could be negotiated
based on customers' request, including chamber dimension, working Temperature,
controlling method and number, traction way and speed as well as heating power.
Basically, a brick kiln consists of two main parts. One is drying chamber. The
other is tunnel kiln. There is no special burning system for drying chamber.
The extra heat used in tunnel kiln will be feedback to drying chamber through a
pipe system.
