Is the tail pulley usually larger in diameter than any other pulley in a conveyor system?

In a conveyor system, the tail pulley is generally not larger in diameter than the other pulleys. Typically, the tail pulley is designed to be smaller than the drive or head pulley. This size differential helps maintain the proper tension and alignment of the conveyor belt. The drive pulley is critical for moving the belt and therefore is often larger to facilitate better grip and efficiency.

While there may be variations in specific conveyor designs or configurations, the standard design principle is that the tail pulley serves primarily as a support structure at the end of the conveyor that maintains belt tension rather than actively driving it. As a result, stating that the tail pulley is usually larger than any other pulley does not align with common engineering practices and standards in conveyor system design.
