Low cost brick firing tunnel kiln

 

A tunnel kiln is a type of continuous kiln that is typically open on both ends and heated centrally. Bricks, carried by the kiln cart, pass through the kiln in an uninterrupted fashion, allowing large volumes to be processed without shutting off the kiln between batches. 

 Production capacity of Tunnel kiln. The production capacity is determined by the width of tunnel kiln.

The features of tunnel kiln as following: 

1. Operating temperature up to 1000 to 1280. Fast firing and according to various types and shapes of work pieces.

2. Fully automatic temperature control provides economic fuel consumption.

3. The tunnel kiln is equipped with high efficiency burner and fuels can be fired completely without any air pollution. 

4. The quality of firing products is very stable thus reducing unacceptable finished products.

 

Tunnel kiln is the most popular kiln to adopt for building clay brick factory. Our company provides the engineering, procurement and construction of tunnel kiln of different capacities with modern technology.

Details of brick production line:

1. Clay is loaded into box feeder. Belt conveyor which is under box feeder carries clay to primary roller crusher. The size of clay is 5 mm after crushing.

 2. Clay is crushed one more time by finess crusher to 3mm. It is then transported by belt conveyor to mixer where water is added into clay.

 3. Clay entered into extrusion mixer where it is mixer and extruded to enhance the plasticity to make good brick. The brick machine extruded the solid and smooth mud strip

 4. Mud strip is cut into green bricks with required size by column cutter and green brick cutter.

5. Green bricks are transported to dryer. The water content after drying will be below 6%.

 

6. Dried bricks are moved to kiln, where bricks are fired at around 900°C. Finished bricks will be produced after firing.
