We offer a broad range of durable replacement parts for vertical roller mills.

Replacement wear parts such as tires, grinding ring segments, armor rings and spindle shields are cast from our high chromium alloy irons and fully heat treated for optimum mechanical properties. Tires and grinding ring segments are also accurately machined to tight tolerances for precise fit.

Parts requiring drilled or tapped holes such as roller bosses, clamping rings and dam ring segments are made of carbon steel or high strength steel. They are heat treated to provide the best combination of hardness and toughness for long, trouble-free service.

Columbia Steel district managers and product engineers are responsive to customer requests for product improvement. As a vertically integrated plant, we can easily deal with the changes in design, metallurgy, heat treatment and machining.

Controlling every facet of manufacturing at one location helps us minimize lead-times and maximize quality. All Columbia Steel parts are American made and guaranteed for proper fit, performance and customer satisfaction.
