Cleaning Return Rollers with Helical Steel Cage - Where used?

Time after time, conveyed material adheres to the belt surface. If the material is abrasive, it may wear out the roller shell of the normal steel return rollers; if it is viscous, it adheres to the roller itself, promoting dangerous build up of scale and causing vibration.

A large material deposit may also influence the tracking off of the belt in the return section.

Used in the return section to support the belt when the conveyed material is very adhesive,as with for example clay.

They ma be positioned on any art of the conveyor return section, when it is relatively short.

When those rollers are produced with a spiral steel cage, it is attached to the wto end caps with similar characteristics to the HDS rollers series.

The spiral cage, in permanent contact with the diry side of the blet, removes material from the belt using it's natural rotary cleaning action

The rollers hould be installed in a way that the spiral moves the materials toward the edge of the belt.

These rollers must not be employed as belt snub rollers.
