External Wear Liner Stops Spillage On Belt Feeders
At a generating plant, 5000 tons per day of PRB coal are metered via belt feeder onto conveyors and into the plant's ten bunkers. With surge of material as railcars unload, combined with the high head pressure from the hoppers, the belt feeders suffered extensive spillage. This spillage was compounded by the worn-out condition of the chutes.

Belt Support Products Solve Fugitive Dust And Spillage Problems
A coal plant had spillage and dust issues at two conveyor transfer points, because material was loaded onto the belts traveling 500 fpm with little control over impact or settling. The result was excessive fugitive dust throughout the facility. Inadequate chute control caused spillage to get caught between the belt and rubber tail pulley, damaging both.

Replacing Inadequate Equipment Improves Productivity
A coal mine was experiencing heavy spillage and system damage along the length of a main conveyor due to inadequate loading zone equipment. Impact idlers allowed excessive belt sag, causing high volumes of spillage. Dust and fines fouled idlers, and rocks got lodged between the belt and the skirt, resulting in unscheduled downtime due to frequent equipment failures and chute liner replacements.
