Tail Pulley
Return/Tail pulleys are used to redirect a conveyor belt back toward the drive pulley. Conveyor tail pulleys can have internal bearings or can be mounted in external bearings and are usually located at the end of the conveyor bed. Conveyor tail pulleys commonly serve the purpose of a Take-Up pulley to keep tension on the belt. The tail pulley is located at the loading end of the belt. It comes with either a flat face or a slatted profile (wing pulley), which cleans the belt by allowing material to fall between the support members.
Joyroll pulleys using international standard design and manufacturing technology, we can produce Drive/head pulley, tail pulley, snub pulley, bend pulley and take-up pulley.

THE LAGGING OF A RETURN TAIL PULLEY.
Pulley laggings use on a variety of pulleys that provides a cost-effective and most effective solution to correct a belt slippage, increase friction and prevent material build-up, along with additional long term system benefits. Joyroll’s laggings with rubber or ceramic tiles embeddedinto rubber afford excellent grip between belt and pulley lagging in both directions; what’s more, ceramic pulley lagging provides the solution that conventional rubber lagging fails to correct a belt slippage and/or lagging wears prematurely.
