Conveyor Belt Inspection Identifies Carryback & Belt Wandering

PROBLEM

QC1+XHDThe plant handles 1,000,000 tons of PRB coal per year and was experiencing carryback and belt wander on the rail unloading belt feeders. The carryback was reducing efficiency and profitability and increasing maintenance and cleanup expenses. The buildup of material on rolling components was also contributing to increased power consumption and the wandering belt. Unsafe working conditions were a concern due to material accumulation on floors and walkways, creating slip/trip hazards along with fire hazards.

SOLUTION

martin-trackerAfter analyzing results from the Martin® Walk the Belt™ , a detailed inspection of the entire conveyor system, Martin recommended upgrading the existing belt cleaners to properly remove carryback and installing lower trackers to resolve the belt tracking issues. Martin provided two primary belt cleaners, the Martin® QC1+™ Cleaner XHD,  and two heavy-duty lower Martin® Trackers™.

RESULTS
