The super long distance high temperature resistant belt conveyor manufactured by North Heavy Industry Co., Ltd. is one of the most high temperature resistant belt conveyors in the world.

"Ever since this long transportation line was put up, the old smoky weather is gone." A 22.331km cement clinker transportation line gallops on the land of Wuyue. This is a complete set of belt conveyor equipment with high temperature resistance, large capacity and super long distance independently developed by North heavy industry of Fangda group. Recently, the equipment has successfully passed the evaluation of scientific and technological achievements organized by Zhongke hechuang (Beijing) scientific and technological achievements evaluation center, marking a breakthrough in the technology of ultra long distance high temperature bulk material conveying equipment.

Avoid environmental damage caused by cement transportation

Changxing, Zhejiang Province and Guangde, Anhui Province are important cement clinker production bases. They are rich in limestone, sand shale and other mineral resources, and have many clinker production enterprises. Due to the limitation of natural environment and geographical conditions, the output of cement clinker and cement products need to be transported by car for short distance, transferred to the wharf of Huzhou Southern Logistics Co., Ltd. in Xiaopu, Changxing, and then transported by water to Huzhou, Jiaxing, Ningbo, Shanghai and other markets.

Before the completion of the transportation line, many cement enterprises have about 12million tons of cement clinker transported by car in short distance every year and run on local roads all year round. Because this transportation line is very important to the economic development of Yangtze River Delta, the transportation volume is very large, and the long-term use leads to mottled and broken roads. The dust will cover the day in sunny days, mud will splash in the sky after rain, there are many hidden dangers of road traffic safety and great pressure of environmental damage. Local residents have strong response.

To solve this problem, we need to find a way to fundamentally avoid the environmental damage caused by the transportation of cement products. In this context, the high temperature resistant and large capacity ultra long distance belt conveyor equipment of Fangda Group North Heavy Industry Co., Ltd. has become the best choice to meet the demands of the people. After more than two years of operation, the life of local people has been completely changed.

The villagers of Hexi village along the line said that in the past, when vehicles came and went, their homes were always covered with dust, and the windows could never be cleaned. In the middle of the night, there were always horn sounds of vehicles going back and forth. Now, the number of vehicles is significantly reduced, and they can see the blue sky again, so they can have a good sleep. With the reduction of vehicles, the local traffic safety has also been significantly improved. According to the relevant personnel of the traffic police brigade of the County Public Security Bureau, with the official use of the conveyor belt, the traffic accident rate of this section has decreased significantly, and the traffic safety has been effectively guaranteed.

"Green development" comes from scientific and technological innovation

How does heavy machinery manufacturing serve ecological development and environmental protection? Beibu heavy industry has found a new way on the road of "green development".

In the development process of high temperature resistant and large capacity ultra long distance belt conveyor complete equipment, the traditional safety monitoring system is changed, the whole machine realizes the high intelligence of operation and monitoring, improves the operation efficiency and reduces the labor pressure. The application of a number of energy-saving technologies has reduced the total installed power by 15%, saving a lot of construction investment.

At the same time, it also provides ideas for the research and development of energy-saving technology of belt conveyor, and provides successful experience for the development of belt conveyor in the direction of longer distance, larger capacity, lower energy consumption and green environmental protection.

According to the introduction, 21 belt conveyors with a total length of 22.331km and an annual conveying capacity of 10.5 million tons were built in cooperation with Huzhou Southern Logistics Co., Ltd., of which the longest single machine distance is 11.75km, the highest belt speed is 4m / s, the maximum transportation capacity is 3000t / h and the highest material temperature is 175 ℃.

It is reported that through the "all electric logistics" mode of all electric transportation, all electric storage, all electric loading and unloading, and all electric berthing, the whole process "zero emission" transportation system has been realized. This cement clinker "air transportation corridor" can reduce 2400 vehicle trips per day, and save 2026 tons of fuel oil in the whole year.
