Pump truck mixing blades are core components in the concrete hopper of truck-mounted concrete pumps. Their main function is to continuously agitate the concrete in the hopper during pumping operations, preventing concrete segregation (separation of aggregates and mortar) and ensuring a uniform, consistent concrete mix for smooth delivery through the pipeline. 

Typically made of high-wear-resistant materials (e.g., Q355B steel with hardfacing layers or cemented carbide inserts), these blades withstand the abrasion from concrete aggregates, extending service life. Their optimized curved design enhances mixing efficiency while minimizing resistance, avoiding concrete accumulation in the hopper and reducing the risk of pipeline blockages—critical for maintaining the pump truck’s stable and efficient operation.
