subject: A Comprehensive Introduction To Belt Conveyer [print this page] Belt machine, which is also called belt conveyor, is widely used for transporting machinery in mining, chemical, cement plant.
It is the machinery used to continuously transfer materials on a certain line; it is also known as continuous conveyor. Conveyor can transfer materials in horizontal, inclined and vertical ways, it also can be composed of space transportation line, and the conveyor lines are generally fixed. Conveyor has big transferring capacity and long transferring distance, you can also simultaneously complete a number of processing operations in the transportation process, so it is has very wide application ranges. It consists of two or more pulleys, with a continuous loop of material - the conveyor belt - that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler. There are two main industrial classes of belt conveyors; those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport industrial and agricultural materials, such as grain, coal, ores, etc. generally in outdoor locations. Generally companies providing general material handling type belt conveyors do not provide the conveyors for bulk material handling. In addition there are a number of commercial applications of belt conveyors such as those in grocery stores.
In order to ensure the belt conveyor reliably operates, it is important to timely detect and exclude the possibility of failure, therefore operators must observe the work of transport aircraft at any time, and any abnormal findings shall be processed in a timely manner. Mechanical workers should be inspected regularly and check for anything or parts that need attention, which is very important. For example, a roller, it may be not very important, but high speed conveyor belt may soon wear its crust and expose a blade, the blade could seriously damage an expensive conveyor belt.
Technical advantages of belt machine:
First, belt conveyor operates reliably. In many important production units which need continual operation, such as transportation of coal in power plant, scattered material in iron and steel plant or cement plant, and stevedoring in port, belt conveyors are used widely. Because it would bring sever loss if machines shutdown in these occasions, while belt conveyor can work continuously.
Second, Belt conveyor makes low power consumption. Due to the un-relative movement between material and conveyor, the running resistance is make small (about 1 / 3-1 / 5 of scraper conveyer), and attrition and fragmentation are also small, which is helps for high productivity an beneficial to reduce the production cost.
Third, belt conveyor has adaptable and flexible conveying line. The length of the line is set according to specific circumstance which can be several meters or more than 10km. Equally, belt conveyor can be installed in a small tunnel, also can be mounted on the chaos ground and dangerous area in the sky.
Forth, According to the process requirements, belt conveyor can be fed flexibly from one or more points and unloads to several sections. Belt conveyor would become a major transportation route when it is fed simultaneously from several points (such as the conveyor used in coal bunker) or fed evenly from any point along the belt.
