How to prevent the conveyor belt from running off


Belt deviation is a prevalent issue in the operation of belt conveyors, particularly for return roller belt conveyors used in underground ore mining. This type of material conveying equipment is valued for its low investment, easy maintenance, and robust environmental adaptability. Belt runout poses a significant challenge, potentially leading to torn and damaged edges of the belt, scattered coal, and even fire due to excessive friction.

Understanding the root causes of belt runouts is crucial for effective mitigation. Several factors contribute to this issue, including:

Non-perpendicularity between the centerline of the carrier roller and the conveyor belt.
Misalignment of the pulley with the conveyor belt's centerline.
Uneven force distribution on the conveyor belt.
Loading imbalances causing runout on one side.
Accumulation of coal powder and other materials in the pulley part.
Subpar quality of the conveyor belt, such as uneven force on the wire rope core.
To prevent belt runouts, various measures can be implemented:

Adopting conveyor roller compactors.
Using a trough roller set with a forward tilt of 2°-3° on both sides.
Installing a self-adjusting roller set with automatic adjustment capabilities.
Utilizing inclined rollers, especially from reputable suppliers like Wuyun idler suppliers, for mobile and hanging conveyors.
Enhancing the assembly quality of the conveyor system, ensuring even belt vulcanization joints, and ensuring that rollers and pulleys are perpendicular to the conveyor's longitudinal shaft.
By implementing these preventive measures and incorporating runout monitoring devices, the conveyor system's reliability can be significantly improved, reducing the occurrence of belt runouts and enhancing overall operational efficiency.
