Problems caused by truck transportation of bulk materials
China’s Zhejiang Changxing and Anhui Guangde are important cement clinker production bases. The two places are rich in mineral resources such as limestone, sand and shale, and have a number of clinker production companies. Due to the constraints of the natural environment and geographical conditions, the export of cement clinker and cement products needs to be transported short-distance by car, and then sent to Huzhou, Jiaxing, Ningbo, Shanghai and other markets by water.
Before the completion of this transportation line, many cement companies relied on short-distance transportation of about 12 million tons of cement clinker each year on local roads all year round. 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 has caused the road to be seriously damaged, there are many hidden road safety hazards, and the dust and mud seriously damage the local environment.
To solve this problem, it is necessary to find a way to fundamentally avoid the damage to the environment caused by the transportation of cement products. In this context, a complete set of high-temperature-resistant, large-capacity and ultra-long-distance belt conveyor equipment has become the best choice for local enterprises. With the reduction of vehicles, the local traffic safety has also been significantly improved. With the official opening of this conveyor belt, the traffic accident rate on this section of the road has dropped significantly, and traffic safety has been effectively guaranteed.
In the process of developing and developing the complete set of high-temperature-resistant and large-capacity ultra-long-distance belt conveyor equipment, the traditional safety monitoring system has been changed, and the whole machine has realized a high degree of intelligence in operation and monitoring, which has improved operating efficiency and reduced 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 for the belt conveyor, and provides successful experience for the development of the belt conveyor in the direction of longer distance, greater capacity, lower energy consumption, and green environmental protection.
This conveying equipment has 21 belt conveyors with a total length of 22.331 km and an annual conveying capacity of 10.5 million tons. The longest single machine distance is 11.75 km, the maximum belt speed is 4 m/s, the maximum transportation volume is 3000t/h, and the maximum material temperature 175 °C. Through the “all-electric logistics” mode of all-electric transportation, all-electric storage, all-electric loading and unloading, and all-electric berthing, the entire “zero emission” transportation system has been realized. This cement clinker conveyor belt can reduce 2,400 round-trips of transport vehicles every day, It can save 2026 tons of fuel throughout the year.
