CONSEQUENCES OF CARRYBACK Carryback is material that sticks to the belt past the discharge point and then drops off along the conveyor™s return run. Without belt cleaners, prevalent carryback causes–Ł through increased expenses for maintenance and cleanup and the loss of material.Ł Material buildup on rolling components leading to seized idlers, wandering belts and increased power consumption.Ł Lower plant morale as employees sense the fiI don™t care if it™s dirtyfl attitude. Ł Unsafe working conditions caused by material Ł Health hazards and environmental concerns created by airborne material.Ł Unfavorable attention from neighbors and regulatory agencies.PROBLEM visit martin-eng.com | call 800-544-2947 | email info@martin-eng.com

CARRYBACK REMOVAL SOLUTION Belt cleaner systems from Martin Engineering make conveyor systems cleaner, safer and more productive. With belt cleaners, minimalized carryback results in–Ł Improved maintenance planning and conveyor availability as emergency outages, unscheduled downtime and fihurry-upfl repairs are reduced.Ł Reduced maintenance expenses by lower labor costs for fewer and faster service procedures. Improved manpower utilization by fewer belt- tracking and material-cleanup chores.Ł Maximized equipment life by fewer replacements of prematurely worn components damaged by fugitive material and buildup.Ł Improved working conditions and plant safety and morale by better housekeeping.Ł Improved community relations and regulatory compliance by reducing environmental pollution.SOLVED 3

Low blade-to-belt pressure allows the primary cleaner to be positioned at a peeling angle against the belt. The use of higher pressure at this angle would endanger the belt, splice or cleaner itself. Primary cleaners are typically installed on the face of the head pulley, just below the material trajectory. The cleaner should be constructed to avoid material buildup and installed so that it is out of the material stream.SELECTION GUIDERequired DataBelt widthHead pulley diameterBelt speedMaterial characteristicsApplication temperatureSelection Process belt width and pulley diameter to select a primary cleaner in the Primary Cleaner Sizing Chart on the opposite page.3.
