Introduction

We are the first and only one kiln company to develop and establish new structure mobile rotary tunnel kiln of freeing from fans at the kiln top, and this technology have obtained patent in China with 12 China national practical new-type patents. We are the first and the only one company of obtaining ISO9001, ISO14001 and OHSAS18001 certification in China’s wall materials firing kiln company by now.

The structure of mobile rotary tunnel kiln body:

Our new structure mobile rotary tunnel kiln include kiln body, circular rails for the kiln move, circular flue connection to kiln body, desulfurizing fan (connection to one desulfurizer) connection to circular flue.

Based on the functions of each section, the mobile rotary tunnel kiln body is divided into 4 sections: drying and moisture eliminating section, preheating section, burning section, insulation and cooling section, and these 4 sections are connected together. The inner side wall and the top of the kiln body install moisture removing pipes and heat feeding pipes respectively.

The patent of our new structure mobile rotary tunnel kiln delete the fans of the kiln body, and take use of the desulfurizing fans to carry out the drying and burning. Freeing from fans of the kiln body, the kiln body don’t have any vibration, which prolong the service time of the kiln and the insulation materials. This new structure Mobile Rotary Tunnel Kiln also delete the check gate between drying section and burning section, which can send the heat to drying section from burning section directly and decrease the heat loss, then meet the requirements of environmental-friendly, energy-saving, high production capacity and less fuel and power consumption.

Advantages

The advantages of mobile rotary tunnel kiln comparing with traditional tunnel kiln:

01


Bigger production capacity:

For traditional tunnel kiln, the biggest sectional width of tunnel kiln is 7.5 meters. For our mobile rotary tunnel kiln, the minimum sectional width is 7.2 meters, and the sectional width can be 7.2, 7.6, 8.6, 9.08, 10.8, 11.2, 12.98, 13.8, 16.38, 18.8 meters, and the length is 150-170 meters.

02


Short kiln construction time:

The mobile rotary kiln can be finished within 4 months. All the kiln parts of the kiln is prefabricated in standardized and large-scale production in factory by uniform specifications, and installed on the plant site. Traditional tunnel kiln can only be constructed with clay bricks and concrete by manual on the brick plant, and more than 6 months are needed for the kiln construction.

03


Less investment:

Freeing from kiln car and no need construction materials (Clay bricks, sand, cement, etc.) for the kiln construction, the investment value of mobile rotary kiln is lower than that of traditional tunnel kiln.

04


Operation directly freeing from baking:

The traditional tunnel kiln must be baked to evaporate a large amount of water brought in during the masonry process before it is put into operation. The mobile rotary tunnel kiln assembly does not contain moisture and can be put into operation directly after assembly freeing from baking.

05


Less maintenance cost and worker cost:

For traditional tunnel kiln, the kiln car maintenance cost is about 50000-100000 USD each year owing to the frequently repairing of kiln car. Moreover, many process are needed, say, ferry car, hydraulic step-by-step pusher, hydraulic pusher, drawing machine, etc., and about 7-10 workers are needed. For mobile rotary kiln, only 2 operators is ok, no need kiln car maintenance cost, no need overhauling for the kiln body within 10 years, and no need overhauling for the refractory insulation materials of the kiln within 5 years.

06


Avoiding bricks collapse:

For traditional tunnel kiln, the bricks are stacked on the kiln car and moves with the kiln car. It is easy to shake and collapse when the kiln car moves. For mobile rotary tunnel kiln, the bricks are stacked on the ground and not move, and the possibility of collapse is much smaller than that of the traditional tunnel kiln.

07


Less coal consumption:

For traditional tunnel kiln, the coal consumption is about 380-450 kcal/kg. For mobile rotary tunnel kiln, it is about 250-280 kcal/kg, and at least 100 kcal/kg can be saved.

Based on the weight of 3.5 KG per pcs brick, 350 Kcal (100 Kcal/kg×3.5 KG) are saved each brick. For the brick plant of 30 million pcs one year, 2100 tons coal (based on the caloric value of 5000 kcal/kg) can be saved each year.

08


More environmental friendly:

There is no fan on the top of the kiln, so the smoke will not be discharged unorganized; And, circular flue and drying room are seamlessly connected, which is energy-saving and environmentally friendly, and will not pollute the environment.
