Classification of conveyor belt structure for transporting materials
Belt conveyors have been widely used in various sectors of the national economy. In recent years, belt conveyors have become an important part of the combined transportation system of open-pit mines and underground mines. Mainly include: steel cord belt conveyors, steel Rope traction belt conveyors and continuous conveying facilities at the disposal site, etc.
These conveyors are characterized by large conveying capacity (up to 30000t/h), wide application range (can transport ore, coal, rock and various powdery materials, and can also transport people under specific conditions), safe and reliable, and high degree of automation , The equipment is easy to maintain and repair, the climbing ability is large (up to 16°), and the operating cost is low. Due to the shortening of the transportation distance, the infrastructure investment can be saved.
At present, the development trend of belt conveyors is: large transportation capacity, large bandwidth, large inclination, increase the length of the single machine and horizontal turning, rational use of tape tension, reduce material transportation energy consumption, and the best way to clean the tape. my country has been in In 1978, the finalized design of the steel cord belt conveyor was completed. The scope of application of the steel cord belt conveyor:
Applicable to the ambient temperature is generally °C; in cold areas, the drive station should have heating facilities; it can be horizontally transported, inclined upward (16°) and downward, and can also be transported in a turn; the transport distance is long, and the single machine can reach 15km ; It can be laid in the open, and the transportation line can be equipped with a protective cover or a corridor; the elongation of the conveyor belt is about 1/5 of that of the ordinary belt; its service life is longer than that of the ordinary belt; its troughability is good; the transportation distance is large.
