Belt Cleaner Information and Selection Guide
Why Are Belt Cleaners Needed?
• Saves Money
Increases belt wear life.
Extends life of rollers, pulleys and splices.
High cost of accidents.
• Reduces Maintenance Costs
Minimizes manual cleanup.
Protects against belt mistracking.
Reduces conveyor component replacement costs.
Reducing carryback from 3% to 1% means a
67% reduction in maintenance costs.
• Keeps Conveyors Running Efficiently
and Consistently
Reduces unscheduled downtime.
Increases production uptime.
• Improves Safety
Reduces housekeeping problems.
42% of conveyor-related accidents happen while
maintenance tasks are being done.
Types of Belt Cleaners
• Precleaners
Mounted on the head pulley.
Mounted below the material flow.
Blade is always narrower than the belt width.
Ideally, the blade covers just the belt's material path.
Removes the big stuff. Typically cleans off up to 80% of the initial carryback.
• Secondary Cleaners
Located just past where the belt leaves the head pulley and anywhere down the beltline.
Special secondaries may allow for mounting under the head pulley.
Blade width is always the belt width or wider.
Removes sticky fines – the final cleaning job.
Cleaning efficiencies can be 90% +.
May require a hold-down roller for maximum performance.
• Specialty Cleaners
Precleaners or Secondaries designed especially for specific or extreme applications.
Definition of Terms
• Carryback -
Material that sticks to the belt after it leaves the transfer point and continues
falling off along the conveyor's return side.
• Material Path -
The section of the belt where most of the material is conveyed. Typically the
center 2/3 of the belt.
• Hold-Down Roller -
A stabilizing roller or pressure roller located on top of the return side
of the belt to prevent belt flap or to provide a consistent flat surface for the blades on a lighter-
tensioned belt.
