Long-lasting wear parts for horizontal and vertical shaft impactors.
Call Columbia Steel for your standard and heavy duty impeller bars, curtain liners and liner plates. We also offer VSI anvils and shoes designed to put more metal in high abrasion areas for longer life between changeouts. Other parts which are available include feed tubes, feed disks, table liners, outer table liners, upper tub liners, lower tub liners, and pedestal skirt liners.
Columbia produces many blow bar designs for cement and aggregate plants. Primary horizontal shaft impactor blow bars in our L98 premium manganese steel routinely outperform competitive blow bars. Our on-site 65,700 square foot machine shop machines the fit requirements to ensure an accurate fit every time.
Our precise alloy chemistry means consistent and reliable wear parts. Horizontal shaft impactors used for secondary crushing and for concrete and asphalt recycling require hard and tough blow bars. Our high level of quality control ensures the exact alloy chemistry, and every alloy steel and alloy iron blow bar is checked for specified hardness to confirm proper heat treatment.
Hundreds of patterns
We currently have hundreds of blow bar patterns for many makes and models of horizontal shaft impactors. Need a custom design? Our engineers and on-site pattern shop are skilled in producing new and customized blow bar designs to best suit the end user’s requirements.
