The roller is an important conveyor accessory used to carry the conveyor belt in the belt conveyor, and it is also an important part of the conveyor equipment. Due to the long distance of the conveyor belt, it is in the form of a roller group in the actual use of the roller. In this way, the distance between each roller is considered. A reasonable design of the roller group can not only save costs, but also ensure the reliable operation of the belt conveyor. At the same time, the belt conveyor can be transported. The longevity of the belt is also beneficial. The premise of the conveyor accessories is that the technical parameters of the conveyor accessories must be understood clearly. The large number of belt conveyor roller groups not only consumes a considerable investment, but as the number of rollers increases, the running resistance of the belt conveyor will also increase, resulting in the specification of the belt conveyor belt and the motor capacity. Increase.
Setting a reasonable distance between the rollers of the belt conveyor is conducive to the smooth operation of the conveyor belt. For the belt conveyor of the bulk material of the conveyor belt, the distance between the broken idlers is about 0.8 to 1.5 meters, and the distance between the idlers in the return section is two to three meters, and the load section of the entire belt conveyor This is true except for special parts. For a given belt conveyor, because of the different tensions and loads, the maximum allowable roller spacing is also different everywhere, and the equal spacing of the rollers does not consider the specific conditions of each part of the conveying. Therefore, using different roller spacings on the same belt conveyor is more in line with the actual situation of the belt conveyor. At the same time, this unequal spacing design can reduce the number of rollers of the entire belt conveyor, thereby reducing the operation of the belt conveyor cost. The unequal spacing of the rollers is designed to increase the spacing of the rollers under the front embankment that does not affect the performance of the belt conveyor. Therefore, it is required that when the belt conveyor idler gap is increased, it must be ensured that the belt conveyor idler can still guide the conveyor belt, and no misalignment is allowed. The conveyor belt groove angle must be protected and no material leakage is allowed.
Increasing the distance between the rollers of the belt conveyor will increase the load on each roller group. In order to ensure reliable operation, it is necessary to ensure that the belt conveyor roller set can bear the corresponding load. When redesigning the technology of the production enterprise, the grading arrangement of the roller spacing of the long-distance belt conveyor will be considered. It can also reduce the number of roller groups and equipment investment under the front embankment to ensure the normal operation of the belt conveyor, and reduce energy consumption. For the classification of the distance between the roller groups, considering the process and design, the belt conveyor can be divided into a section of 30 meters to 50 meters. According to the corresponding calculation, it is concluded that the classification is mainly in the low tension area.
