Analysis of the causes of drum rupture in high-inclination belt conveyors

Thread Content

The high-inclination belt conveyor is a new type of continuous conveying equipment. It features a simple structure, easy maintenance, low space requirement, large conveying capacity, high versatility, and wide applicability. For these reasons, it is widely used in industries such as coal, metallurgy, chemicals, transportation, food processing, home appliances, tobacco, and electricity. In the infrastructure construction module, high-inclination belt conveyors play a very important role. As a powerful, user-friendly, and widely used mechanical device, its drums often crack – what is the reason for this? Let’s take a look at it together today. In today’s era of rapid advancement in industrial technology, the system of high-inclination belt conveyors continues to improve and evolve toward greater diversity. As an important component of such conveyors, the drums, if not properly maintained based on actual conditions, can affect the normal operation of the conveyors and thus impact production processes. This requires an analysis of the drum’s structure and its stress-bearing components, as well as active improvements to the methods used to assess the drum’s strength, in order to meet the needs of current engineering projects. During operation, there are numerous factors that can cause the drums of belt conveyors to crack, such as excessive tension in the conveyor components, which in turn leads to changes in its pulling force ； Or excessive load that prevents it from bearing weight, etc., can all cause the drum to crack. During the operation of the conveyor, it is necessary to increase the tension in order to enhance its conveying capacity; this also increases the positive pressure on the drums to a certain extent. However, due to the insufficient strength of the drum itself, poor quality of the selected steel plate, or inadequate thickness of the steel plate, it is inevitable that the drum will crack. Furthermore, there is another important possibility: insufficient strength in the welding quality of the steel plates, as well as poor welding quality, can also lead to cracking. Since welding is an essential part of the drum’s structure, welding stresses are generated during the welding process; if not properly managed, cracks can quickly appear at the welded areas under pressure. If the drum ruptures, the operation of the large-inclination belt conveyor will inevitably be affected as well. Therefore, during daily operations, we must be aware of the various factors that can cause cracking and take proper precautions to avoid roller breakdown.
