Updates to Superior Exterra belt cleaners


Trio of modifications to popular belt cleaner range designed to reduce maintenance time

SUPERIOR Industries Inc. have made modifications to their Exterra conveyor belt cleaners in order to reduce amount of maintenance time required.

First, a new fast-acting click tensioner is available for the primary and secondary models. After installation, operators simply twist the tensioning unit for a prescribed number of times to set the correct force. Click count instructions are conveniently labelled on the aluminium housing that protects the springs.


Secondly, Superior’s SFL scraper models are now manufactured with a special extruded tube designed to house the patented springs and seal them from fugitive material. The abbreviation SFL means ‘Set for Life’. Exterra belt cleaners with this SFL option require tensioning just once at the time of installation. Accurate tension is then maintained automatically for the entire life of the blade with no maintenance needed.

Thirdly, Superior’s conveyor components engineers recently completed lab and field testing on a new proprietary polyurethane mix. According to Superior, this longer-lasting blade material is more flexible, better able to withstand the beating from belt splices, and wears more effectively.

All Exterra belt scraper blades are developed in house by Superior and several models are specially constructed for aggregate applications.
