Aggregates Industry
Superior’s Aggregate Processing Equipment
Our roots in aggregates date back to 1917 when a small precast concrete manufacturer – Hancock Concrete – was founded in Western Minnesota. A quarter century later, Schmidgall Sand & Gravel was established and Son was supplying Dad with aggregate for the family’s precast plant.
Later – as the sand and gravel deposits spread – it was Grandson’s role to improve mobility of the processing equipment. Neighboring pits noticed and wondered if Grandson could modernize their mobility too.
Improving portability was our great differentiator, with products like the TeleStacker® Conveyor and Trailblazer® Conveyor. Superior expanded regionally, then nationally and eventually internationally. As he built his brand, our founder taught us integrity, humility, work ethic and personal growth.
Today, those values empower our employees who manage our progress as a proud supplier to the aggregates industry. Our equipment now serves aggregate users with crushing, screening, washing and conveying specialties. We offer expertise from “rock face to load out!”
