RULMECA Problem-Solving Tips for Bulk Materials Handling: CORROSION
Our new eight page brochure on belt conveyor drives is filled with useful tips on how to reduce costs, increase safety, and improve system reliability. This newsletter extracts information from that brochure and addresses how to mitigate the effects of corrosion on exposed drive components such as the ones illustrated at the salt mine shown above.
Replacing the exposed motor, gearbox, chain, sprockets, coupling, pillow blocks, and personnel guarding with an internally-powered Motorized Pulley has dramtically improved system reliability at this salt mine.
The "before" and "after" photos above compare an exposed and corroded conveyor pulley pillow block bearing on a live shaft with a hermetically-sealed bearing on a Motorized Pulley dead shaft. Protecting mechanical components within the oil-filled pulley shell is what yields a long service life.
