Shaanxi IBRICK Technology Co., Ltd. is located in Xi'an, China, one of the four world-known major ancient civilization capitals, the original place of the Qin Bricks and Han Tiles and the ancient capital of China.

IBRICK is the technology initiator whom firstly professional supply clay brick sintering two-step stacking-firing process in the world. We commitment      to the technological innovation, management innovation, and steady enlarge the business team all the times. The company has always implemented rigorous, secure, and integrated industrial chain management and professional provide engineering management, technology solutions, equipment manufacture, trade and etc. for the clay sintering brick project all around the world.Now we provide solutions for the world-wide clients in producing the following items: Facing Bricks, Paving Bricks; Insulating Block; Hollow Bricks; Western-style Tiles; Split Bricks; Sand-lime Bricks or Blocks; Autoclaved Fly Ash Blocks or Blocks and Cement Sticking Bricks, etc.

As an ambitious and vigorous enterprise, we are committed to technology innovation, management innovation and gradual enlargement of our team. We also have extensive and close technological exchange and cooperation with world-famous manufacturers with advanced technology in Germany, Italy, etc.
The company has nearly 40 professional and technical personnel, of which: 5 senior professor, 15 senior titles, intermediate grade 6, The company completed projects, engineering design, technical services, trade and other business throughout the world.  The projects of building materials which were made of coal ash, shale, coal gangue, clay, construction waste and other raw materials, through out Xinjiang, Guangdong, Zhejiang, Shanxi, Sichuan, Shaanxi, Tibet and other provinces in China.

There are more than 30 production lines put into running, while the company actively open up overseas markets, and set up sintering brick & other building material production lines in Russia, Bangladesh, India, Nepal, Colombia, Mexico, South Africa, Myanmar and other countries. What's more, It created appreciable value to cooperative enterprise.

Drying and firing
Drying and firing will adopt two times stacking=firing process. Drying chamber adopts 2 groups (each group with 5pcs) of tunnel dryer with inner width of 4.66meters.
The heating source is cooling heat of the dried-products and high temperature smoke heat from the tunnel kiln.
The smoking air feeding temperature and air volume will be adjusted through the drying air-adjustment-system, so as to ensure the drying quality of green bricks. Well-dried green bricks will be unloaded from drying cart by undercarriage system and re-stacking on the transfer belt in the molding section automatically, then the well-dried bricks will be stacked on the kiln cart and sent to front end of tunnel kiln by ferry car. 
Tunnel kiln adopt 2 set of large section with inner width of 6.9meter, it is designed as a flat ceiling structure. It is adopt external firing and baking process with the main heat source of natural gas(80%) and assist heat of coal dust mixed into raw material(20%), this kiln is suitable for firing products with 1300-1500KJ/Kg.
Tunnel kiln has smoke-releasing system, recycling system, waste-heat recovery system, cooling system and pressure balancing system. This kiln has following features: large section, high yield, small section temperature difference, good heat preservation effect. Meanwhile, the kiln auto-control system is equipped to ensure the baking heat parameters are stable, so the firing quality is guaranteed.
The products are Discharged from the kiln car by de-hacking machine and taken to the products yard by folk lift trucks.

Tunnel kiln system
The technology choose flat celling tunnel kiln. The tunnel kiln has complete system of
smoke discharging, cooling, heat releasing, pressure balancing under the kiln car, running and test system. Baking curve inside of the kiln will be more reasonable through the adjustment of those system.
There are entrance and exit doors at both ends of the tunnel kiln. At the entrance side, there is a preparatory room, and a cut-off door between the preparatory room and the kiln joint zone. Thus it effectively avoid entering the cold air and ensure the baking system of the kiln.

Tunnel kiln structure
Red brick is laid for the pre-heating zone and cooling zone where the temperature is below 200ºC. The rest part, baking zone and the innermost wall of insulating zone are adopt clay refractory brick. The clay insulting bricks will be used for laying the insulting area. Meanwhile, refractory fabric felt (for the relative part of temperature curve above 600 Celsius) or rock wool felt will be used for stuffing and red bricks will be laid on the external wall.

Kiln roof structure:
One kiln car space remained in low temperature zone on both side, which adopt cast-in concrete top slab. For other position, clay material plate, hanger plate through davit hang under H type steel beam by cast product. Both sides wall body support the main beam's weight. High aluminum cotton ,refractory fibro felt, rock wool felt, rock wool board are put on the refractory hander plate, which compose complex insulation layer.
The crack between the top plate will be impacted by high aluminum fiber .High temperature binder is being filled up to the gap between the boards, and is being painted on the upside of the insulating layer, thus to ensure the material's insensitivity and structure's durability.
