Beijing Jinglianxin – Appliaion of SOUTH Asphalt Mixing Plant and Asphalt Hot Recycling Equipment
Beijing Jinglianxin Road Material Co.,Ltd (hereinafter referred to as “Jinglianxin”), a large enterprise whose main production of highway construction roadbed material and pavement material, are one of enterprises who supply largest asphalt mixture in Beijing and surrounding areas. Jinglianxin has invested and constructed many asphalt mixture production bases in Tongzhou District, Shunyi District and Changping District of Beijing and Sanhe city of Heibei Province, which include Tongzhou District Maju Bridge Asphalt Mixture Production Base, Shunyi District Beiwu Asphalt Mixture Production Base and Sanhe City Shizhuang Asphalt Mixture Production Base. They have purchased seven sets of asphalt mixing plants and three sets of asphalt hot recycling equipment from SOUTH since 2003. Main production of Jinglianxin is supplied to Beijing-Shenyang, Jingkai, Beijing-Chengde and other high-speed highway and state’s major highway construction projects of Beijing Four Ring, Five Ring and Six Ring, besides directly supplied to road engineering and municipal engineering, and now is expanded to Tianjin, Tangshan and other areas.

The corporation of Jinglianxin and SOUTH originated from mutual confidence and highly acknowledgement with SOUTH’s enterprise spirit about focusing on products and technologies. In 2003, Jinglianxin purchased SOUTH LB3000 Asphalt mixing plant for the first time. The plant was put into operation officially in 2004 and produced millions ton of asphalt mixture during twelve years, now it can still perform production tasks normally in spite of being charged with high strength performance. The second SOUTH LB3000 asphalt mixing plant that Jinglianxin purchased in 2004 can be witnessed durability from a little vibration motor in vibration screen. This vibration motor was imported from Italy and was still employing till now during the period of eleven years due to regular equipment maintenance and itself durable performance. As vulnerable parts of mixing equipment, lining board, mixing blades and mixing arms in mixing crock whose rub fastness directly affect equipment usage and production period. According to statistics, lining board, blades and arms of mixer whose usage output can reach more than 3 hundred thousand tons, up to 4 hundred thousand tons after using ten years, which means those machines have high wear resistant degrees.

Jinglianxin undertook massive asphalt mixing supply projects in the regions of Beijing, Tianjin and Hebei due to itself power and influence. Therefore, the continuous production ability of asphalt mixing plant is an obligatory option of choosing equipment supplier for Jinglianxin. Taking these two sets of LB3000 asphalt plant in Shuiyi Beiwu asphalt concrete as an example, the peak of production of these two equipment reached 7000 tons every day from Spring Festival till now. This type of equipment can produce 245 tons every hour and more than 20 hours every day in a continuous manner under the situation of producing bed material. High-strength production tasks and long-time operation illustrate that SOUTH’s equipment stands the test of advanced production and receives recognition of Jinglianxin. With the enhancement of environmental protection in the production process and strict control of atmospheric emission in the regions of Beijing, Tianjin and Hebei, the environment issues in the asphalt mixture production have become the principal events of producing enterprises. Burners of all asphalt mixing plants in Jinglianxin adopt natural gases which can avoid gas pollution issues with burning oil just like ordinary factories. Besides, severe pollution, heavy burden on dust collection system and high replacing frequency of bag filter with burning oil outweigh the advantage of low production expense. Natural gas has advantages on environmental protection as clean energy which are never discharging harmful fume, prolonging the service life of bag filter and descending environmental costs. Considering burning costs, burning gas is more expensive 2 or 3 Yuan than burning oil as producing one ton asphalt mixture. But if you consider maintenance costs of bag filter, you will find out that burning gas is cheaper than oil and beneficial to atmospheric pollution control.

Old Material Recycling, Asphalt Hot Recycling

Asphalt pavement is the main surfacing way of pavements, so there are plenty of waste asphalt mixtures every year all around the country. Take Beijing as an example, RAP reaches 2000 thousand tons every year as it wastes resources and pollutes environment. With the development of recycling technology of waste asphalt mixtures, waste asphalt mixture recycling appliaion is becoming mature and accepted by more and more people. Up till now, Beijing government has tax preferential policies on recycling waste asphalt mixture and they encourage recycling waste asphalt mixture. As for asphalt mixture producing enterprises, only put into some equipment purchasing expenses and add hot recycling modules on former equipment, then they can recycle waste asphalt mixture and adjust add proportion of waste asphalt mixture according to the production demand. It not only saves enormous asphalt material costs but also gains tax preferential policies. Moreover, it consumes plenty of waste asphalt mixture, releases environmental pressure and reaps high payoffs for company.

Jinglianxin undertook a lot of projects which owners ask for using waste asphalt by themselves response to policies support and market stimulation. In some old road transformation cases, waste asphalt pavemill materials were even provided by owners. Add waste material milling from former pavements with native asphalt at the requirements of owners’ proportion, and then use them on the former pavements. Waste materials go to the place where they come from and it solves waste material on the spot. According to the feedback from site supervision of owners, adding recycling materials cannot degree mixture performances and sometimes oilstones are bigger than those native ones, so quality is out of question.
