China Mobile tunnel kiln for burning clay brick manufacturers - Yingfeng Machinery
We are the first one kiln company to develop and establish new structure mobile rotary tunnel kiln , 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.
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 keeps one small fan of the kiln body which can better increase of air flow for brick drying , and take use of the desulfurizing fans to carry out the drying and burning. 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.
Drying and moisture eliminating section.
The kiln body moves forward, and the mud bricks go inside of drying and moisture eliminating section of the kiln, and dried by the recyclable flu gas of high temperature till the mud bricks temperature reach 200 ℃ or so.
The bricks enter preheating section after dried to 200 ℃ or so at drying and moisture eliminating section, and reach 600 ℃ or so by the recyclable flu gas of high temperature coming from burning section.
The bricks are dried to 850-1050 ℃ in burning section till the bricks are fully burned.
The bricks are cooled by the cold air, and the cold air are heating by the heat from burned bricks to change to be hot flu gas, most of which are recyclable for the drying medium of drying section.
