Reasons for Belt Misalignment in Belt Conveyors

When using belt conveyors, we all know that belt deviation is a common malfunction. If handled properly, it may only temporarily affect production. However, if not addressed correctly, it can lead to belt wear and potentially cause the entire belt to become unusable, halting production. With such significant risks, what are the causes of belt deviation?

1. Uneven tension on both sides of the belt between the drive and tension drums results in inconsistent pressure on the drums by the belt's sides. The belt's passage over the drums exhibits deformation and slipping, the extent of which is related to the pressure exerted on the drums. Due to the differing pressure, the degree of slipping and the elongation deformation of the belt vary.

2. The belt on the side with greater tension experiences more deformation and less slippage, thus moving at a faster pace. Consequently, it undergoes lateral movement in the same direction, which further exacerbates the uneven tension on both sides of the belt, creating a vicious cycle. This intensifies the lateral movement of the belt, leading to misalignment. The misalignment causes the belt to rub violently against the standing roller, significantly reducing its lifespan and consequently increasing production costs.
