A deep salt mine and barge loading terminal in Avery Island, Louisiana, has battled the effects of corrosion and abrasion, due to salt accumulation in the humid Louisiana marshland, by converting its exposed conveyor drive systems to internally-powered conveyor drive pulleys.
They use only two different belt widths in their plant and could therefore standardise on two Rulmeca motorized pulley models to limit the number of spares protecting the system. Special features incorporated into these pulleys include inorganic zinc rich primer, 12 mils of Carboline Carbomastic CM15FC paint, regreasable labyrinth seals and stainless steel shafts. The paint system protects steel and cast iron surfaces while the labyrinth seals provide a grease barrier to protect all double lip shaft seals. In addition, Class H motors and synthetic oil protect the drive system from the heat of the Louisiana marshland climate.
