Application

Rubber belt conveyors are used for hori-zontal and inclining transport of loose, bulk

materials.

The FLS rubber belt conveyors are nor-mally supplied with EP fabric rubber belt-ing to DIN 22102 specifications and areequipped with the special FLS supportingidlers with sealed- for-life ball bearings andgrease packed labyrinth seals.

The loading and transfer points are de-signed for trouble-free operation of the con-veyors. Dust filters are fitted where required.

The supporting structure is manufacturedof tubular framework. This construction fa-

cilitates the mounting and adjustment of theidlers.

The belt conveyors are equipped with ef-fective scrapers for belt and pulleys andwith special self-cleaning idlers for the re-turn side of the belt when transporting stickymaterials.

Design and operation

Belt conveyors with centre distance >100 m

are equipped with sets of self-adjusting sup-porting idlers on the return part to ensure thecorrect training of the belt.

The FLS rubber belt conveyor is driven ei-ther by separate motor and gear or bymotorised driving pulley.

Belt tension is maintained by screw type take-up (centre distance < 30 m) or by gravitytype take-up (centre distance > 30 m).

The maintenance requirements of the FLSrubber belt conveyors are negligible. Theidlers with sealed-for-life ball bearings aremaintenance free. The labyrinth seals can

be recharged.

The FLS rubber belt conveyor can be sup-plied troughed, flat or flat with raised edges.FLS also manufacture long distance belt con-veyors and have supplied rubber belt con-veyors up to 22.5 km in length divided into2.5 km sections.
