A Major Technological Breakthrough Has Been Made in the Ultra Long Distance High Temperature Bulk Material Transportation Technology By NHI

Published:2021-06-16

"The old smoky weather has gone away since the long transport line went up." A cement clinker transportation line stretching 22.33 kilometers, the longest in China, gallops on the land of Wu –Yue Area. This is a complete set of belt conveying equipment with high temperature resistance and large volume and long distance independently developed by Fangda Group NHI. Recently, the equipment successfully passed the scientific and technological achievement evaluation organized by the Science and Technology Achievement Evaluation Center of China Science and Technology Cooperation (Beijing), which marks a breakthrough in the ultra-long distance high-temperature bulk material conveying equipment technology has been monopolized by developed countries. At the same time, it has also laid a solid foundation for NHI to base itself on the domestic market and realize the domestic and international double-cycle strategy.

"The gloomy sky is for misty rain, and the people are waiting for"

Zhejiang Changxing and Anhui Guangde are the most important cement clinker production bases in the south of Shanghai. They are rich in limestone, sand shale and other mineral resources and have a number of 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 truck for short distance and transferred to Huzhou Southern Logistics Co., Ltd. wharf in Changxing Xiaopu for transit, and then shipped to Huzhou, Jiaxing, Ningbo, Shanghai and other markets.

Before the completion of this transportation line, many cement enterprises annually about 12 million tons of cement clinker on the local roads by relying on short distance transportation vehicles. Because this transportation line is very important to the economic development of the Yangtze River Delta region, the transportation volume is very large, and the long-term use of the road resulting in mottled and dilapidated. In sunny days, dust covers the sky, and mud splashes all over the sky after rain. There are many road traffic safety risks, and the pressure of environmental damage is huge. Local residents have a strong reaction. The solution to this problem is to find a way to avoid the environmental damage caused by the transport of cement products. Under this, Fangda Group NHI's high-temperature resistant, large-volume and ultra-long distance belt conveying equipment has become the best choice to meet people's demands. Through more than two years of operation, it has completely changed the lives of local people. Villagers in Hexi Village along the route said that the trucks came and went in the past, their homes were always covered with dust, windows were never cleaned, and trucks always honked back and forth in the middle of the night. Now, there are fewer trucks, and they can see the blue sky again, so they can sleep peacefully. 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 this conveyor belt, the traffic accident rate of this section has decreased significantly, and the traffic safety has been effectively guaranteed

"Green Development" stems from scientific and technological innovation

How does heavy machinery manufacturing serve ecological development and environmental protection? NHI has taken a new path on the road of "green development". In the process of developing a complete set of high-temperature resistant, large-volume and ultra-long distance belt conveyor equipment, aiming at the local complex terrain and the practical needs of users to improve the environmental pollution, the green development of port logistics is realized and the operation cost of equipment is saved on the basis of a large number of studies and digestions of relevant academic papers and works in the domestic and overseas. The comprehensive analysis of the belt conveyor's various operating conditions are carried through the advanced design, analysis software. A major breakthrough has been made in the design and technology of a complete set of equipment for high-temperature and large-volume and ultra-long distance cement clinker belt conveyer, which changes the traditional safety monitoring system and realizes the highly intelligent operation and monitoring of the whole machine, improves the operation efficiency and reduces the labor pressure. The application of a number of energy-saving technologies reduces the total installed power by 15% and saves a lot of construction investment, successfully completed the project development and research tasks. It provides ideas for the research and development of energy saving technology of the whole belt conveyor, and provides successful experience for the development of the belt conveyor towards the direction of longer distance, larger transport volume, lower energy consumption and green environmental protection.

"New Development Concept" works with business partners to fulfill China's commitments

"Carbon peak" is China's commitment to stop the growth of greenhouse gas emissions from coal, oil, natural gas and other fossil energy burning activities, industrial production processes, land use change, forestry and other activities (including greenhouse gas emissions caused by the use of purchased electricity and heat, etc.) and reach a peak before 2030. This is China's solemn commitment to the world and the mission of a responsible major country. Fangda Group NHI is known as "the cradle of heavy machinery industry of new China". The "eldest son feeling" of sharing the country's worries has always driven the enterprise to complete one breakthrough after another. Entering the new historical development stage, Fangda Group actively responded to the call of the CPC Central Committee and participated in the mixed ownership reform of NHI under the correct leadership and vigorous promotion of Liaoning Provincial Party Committee and Shenyang Municipal Party Committee and Municipal Government. Through the implementation of mixed reform, the grassroots party building work of NHI has been strengthened. Adhering to the corporate culture of "Party building is the soul", guided by the policy of the Party, taking the rise of national industry as its own responsibility, it actively responds to the call of the country, explores all kinds of advanced technologies regardless of the cost, and makes every effort to achieve "green development" in the upstream and downstream areas of the industrial chain. After years of technological accumulation, NHI has reached the leading level of the industry in many fields, and some fields have reached the world's advanced level. It has broken foreign monopolies repeatedly, and played an exemplary role in the transformation and upgrading of the national equipment manufacturing industry.

This conveying equipment, built in cooperation with Huzhou Nanfang Logistics Co., Ltd., is a complete set of belt conveying equipment with the largest comprehensive parameters, the most complex working conditions and the most technical difficulty independently designed, manufactured and tested by China at present. There are altogether 21 belt conveyors with a total length of 22.331km and an annual conveying capacity of 10.5 million tons, among which the longest single machine distance is 11.75km, the highest belt speed is 4m/s, the maximum transport capacity is 3000t/h, and the highest material temperature is 175℃. It is the largest belt conveyors operating in the world for conveying high-temperature materials at present. Through the cooperation with NHI, Huzhou Southern Logistics Co., Ltd successfully created the first all-electric transportation, all-electric storage, all-electric loading and unloading, all-electric mooring ship "all-electric logistics" mode to achieve the whole "zero emission" transportation system. The longest cement clinker "air transportation walkway" in China can reduce the number of transportation vehicles to 2,400 trips a day and save 2,026 tons of fuel a year, contributing to China's "carbon peak" goal. The complete set of belt conveyor equipment with high temperature resistance and large volume and long distance, which solved the clinker transportation problem for enterprises in the south of Huaikan and Baixian in Changxing, achieved good economic, environmental and social benefits, which was praised by local government departments and surrounding residents. At the same time, the successful application of this product has also brought a leap in energy saving technology for the whole belt conveyor.
