Introduction
Introduction
General
CleanScrape
®
is a Pre-Cleaner which is installed diagonally across the
discharge pulley and forms a three dimensional curve. The cleaner has a
matrix of tungsten carbide scrapers incorporated into the main rubber body
during the vulcanization process. It is tensioned against the belt at an
extremely low contact pressure. On a dual-cleaner system, a Secondary
Cleaner is installed immediately following the Pre-Cleaner to remove
stubborn material left on the conveyor belt. If a Pre-Cleaner cannot be used
because of space limitations, Secondary Cleaners can be installed alone.
Multiple Pre-Cleaners and/or Secondary Cleaners may be required to clean
the belt. If the material-handling process or product could be affected by
contamination from the use of these belt cleaners, the user is responsible for
taking the necessary steps to prevent contamination. Consult Martin
Engineering or a representative for alternate belt cleaners or belt cleaner
locations to use where contamination may be an issue.
Installations
without chutework
These procedures were written for equipment that is being installed on
enclosed pulley chutework. If the pulley is not enclosed, the equipment should
be installed using the best available field resources and methods to ensure that
the critical dimensions are followed for proper installation.
Belt cleaner
inspection access
If the belt cleaner is installed on enclosed pulley chutework, at least one
Martin

Inspection Doors are
available from Martin Engineering or a representative.
