SUPERIOR Industries Inc., US-based manufacturers and global suppliers of bulk material processing and handling systems, have expanded the blow bar metallurgy options for their Sentry horizontal-shaft impact (HSI) crushers, giving aggregate producers and recyclers more ways to match the wear part to the material they are crushing.
By expanding available combinations of manganese, chrome alloy levels, ceramic enhancements and heat treatments, Superior say they can better match blow bar performance to the crushing circuit, feed material and operating conditions.
‘Wear life is naturally one of the first things operators consider when selecting a blow bar, but the longest-lasting blow bar isn’t necessarily the best blow bar if it isn’t right for the application,’ said Superior’s crushing product manager, Jarrod Adcock. ‘It’s about balancing abrasion resistance, impact resistance and operating conditions to achieve greater uptime at the lowest cost per ton.’
HSI crushers encounter a wide range of materials and operating conditions. A primary crusher may see large feed directly from the rock face, while a secondary machine may process more controlled feed. Recycling applications may involve reclaimed asphalt, concrete and potentially tramp metal. Abrasiveness can also vary significantly from one site to another.
Superior’s approach begins with selecting a blow bar appropriate for the general application, then evaluating actual operating conditions and wear performance before moving to another metallurgy if warranted. That strategy prevents producers from paying for a premium metallurgy they do not need or selecting a bar that is too brittle for their application.
‘You could buy the most premium blow bar available, but if your application doesn’t need it, you’re spending more money than necessary,’ said Mr Adcock. ‘The economics go beyond the purchase price, too. A bar that wears prematurely means more frequent replacement, more labour inside the crusher and more production time lost to maintenance.’
